A new study found that code generated by AI is more likely to contain made-up information that can be used to trick software into interacting with malicious code.

AI-generated computer code is rife with references to nonexistent third-party libraries, creating a golden opportunity for supply-chain attacks that poison legitimate programs with malicious packages that can steal data, plant backdoors, and carry out other nefarious actions, newly published research shows.

The study, which used 16 of the most widely used large language models to generate 576,000 code samples, found that 440,000 of the package dependencies they contained were “hallucinated,” meaning they were nonexistent. Open source models hallucinated the most, with 21 percent of the dependencies linking to nonexistent libraries. A dependency is an essential code component that a separate piece of code requires to work properly. Dependencies save developers the hassle of rewriting code and are an essential part of the modern software supply chain.

****Package Hallucination Flashbacks****

These nonexistent dependencies represent a threat to the software supply chain by exacerbating so-called dependency confusion attacks. These attacks work by causing a software package to access the wrong component dependency, for instance by publishing a malicious package and giving it the same name as the legitimate one but with a later version stamp. Software that depends on the package will, in some cases, choose the malicious version rather than the legitimate one because the former appears to be more recent.

Also known as package confusion, this form of attack was first demonstrated in 2021 in a proof-of-concept exploit that executed counterfeit code on networks belonging to some of the biggest companies on the planet, Apple, Microsoft, and Tesla included. It's one type of technique used in software supply-chain attacks, which aim to poison software at its very source in an attempt to infect all users downstream.

“Once the attacker publishes a package under the hallucinated name, containing some malicious code, they rely on the model suggesting that name to unsuspecting users,” Joseph Spracklen, a University of Texas at San Antonio PhD student and lead researcher, told Ars via email. “If a user trusts the LLM's output and installs the package without carefully verifying it, the attacker’s payload, hidden in the malicious package, would be executed on the user's system.”

In AI, hallucinations occur when an LLM produces outputs that are factually incorrect, nonsensical, or completely unrelated to the task it was assigned. Hallucinations have long dogged LLMs because they degrade their usefulness and trustworthiness and have proven vexingly difficult to predict and remedy. In a paper scheduled to be presented at the 2025 USENIX Security Symposium, they have dubbed the phenomenon “package hallucination.”

For the study, the researchers ran 30 tests, 16 in the Python programming language and 14 in JavaScript, that generated 19,200 code samples per test, for a total of 576,000 code samples. Of the 2.23 million package references contained in those samples, 440,445, or 19.7 percent, pointed to packages that didn’t exist. Among these 440,445 package hallucinations, 205,474 had unique package names.

One of the things that makes package hallucinations potentially useful in supply-chain attacks is that 43 percent of package hallucinations were repeated over 10 queries. “In addition,” the researchers wrote, “58 percent of the time, a hallucinated package is repeated more than once in 10 iterations, which shows that the majority of hallucinations are not simply random errors but a repeatable phenomenon that persists across multiple iterations. This is significant, because a persistent hallucination is more valuable for malicious actors looking to exploit this vulnerability and makes the hallucination attack vector a more viable threat.”

In other words, many package hallucinations aren’t random, one-off errors. Rather, specific names of nonexistent packages are repeated over and over. Attackers could seize on the pattern by identifying nonexistent packages that are repeatedly hallucinated. The attackers would then publish malware using those names and wait for them to be accessed by large numbers of developers.

The study uncovered disparities in the LLMs and programming languages that produced the most package hallucinations. The average percentage of package hallucinations produced by open source LLMs such as CodeLlama and DeepSeek was nearly 22 percent, compared with a little more than 5 percent by commercial models. Code written in Python resulted in fewer hallucinations than JavaScript code, with an average of almost 16 percent compared with a little over 21 percent for JavaScript. Asked what caused the differences, Spracklen wrote:

_“This is a difficult question because large language models are extraordinarily complex systems, making it hard to directly trace causality. That said, we observed a significant disparity between commercial models (such as the ChatGPT series) and open-source models, which is almost certainly attributable to the much larger parameter counts of the commercial variants. Most estimates suggest that ChatGPT models have at least 10 times more parameters than the open-source models we tested, though the exact architecture and training details remain proprietary. Interestingly, among open-source models, we did not find a clear link between model size and hallucination rate, likely because they all operate within a relatively smaller parameter range._

_“Beyond model size, differences in training data, fine-tuning, instruction training, and safety tuning all likely play a role in package hallucination rate. These processes are intended to improve model usability and reduce certain types of errors, but they may have unforeseen downstream effects on phenomena like package hallucination._

_“Similarly, the higher hallucination rate for JavaScript packages compared to Python is also difficult to attribute definitively. We speculate that it stems from the fact that JavaScript has roughly 10 times more packages in its ecosystem than Python, combined with a more complicated namespace. With a much larger and more complex package landscape, it becomes harder for models to accurately recall specific package names, leading to greater uncertainty in their internal predictions and, ultimately, a higher rate of hallucinated packages.”_

The findings are the latest to demonstrate the inherent untrustworthiness of LLM output. With Microsoft CTO Kevin Scott predicting that 95 percent of code will be AI-generated within five years, here’s hoping developers heed the message.

AI Code Hallucinations Increase the Risk of ‘Package Confusion’ Attacks

WhatsApp's AI tools will use a new “Private Processing” system designed to allow cloud access without letting Meta or anyone else see end-to-end encrypted chats. But experts still see risks.

The end-to-end encrypted communication app WhatsApp, used by roughly 3 billion people around the world, will roll out cloud-based AI capabilities in the coming weeks that are designed to preserve WhatsApp’s defining security and privacy guarantees while offering users access to message summarization and composition tools.

Meta has been incorporating generative AI features across its services that are built on its open source large language model, Llama. And WhatsApp already incorporates a light blue circle that gives users access to the Meta AI assistant. But many users have balked at this addition, given that interactions with the AI assistant aren’t shielded from Meta the way end-to-end encrypted WhatsApp chats are. The new feature, dubbed Private Processing, is meant to address these concerns with what the company says is a carefully architected and purpose-built platform devoted to processing data for AI tasks without the information being accessible to Meta, WhatsApp, or any other party. While initial reviews by researchers of the scheme’s integrity have been positive, some note that the move toward AI features could ultimately put WhatsApp on a slippery slope.

“WhatsApp is targeted and looked at by lots of different researchers and threat actors. That means internally it has a well understood threat model,” says Meta security engineering director Chris Rohlf. “There's also an existing set of privacy expectations from users, so this wasn’t just about managing the expansion of that threat model and making sure the expectations for privacy and security were met—it was about careful consideration of the user experience and making this opt-in.”

End-to-end encrypted communications are only accessible to the sender and receiver, or the people in a group chat. The service provider, in this case WhatsApp and its parent company Meta, is boxed out by design and can’t access users’ messages or calls. This setup is incompatible with typical generative AI platforms that run large language models on cloud servers and need access to users’ requests and data for processing. The goal of Private Processing is to create an alternate framework through which the privacy and security guarantees of end-to-end encrypted communication can be upheld while incorporating AI.

Users opt into using WhatsApp’s AI features, and they can also prevent people they’re chatting with from using the AI features in shared communications by turning on a new WhatsApp control known as “Advanced Chat Privacy.”

“When the setting is on, you can block others from exporting chats, auto-downloading media to their phone, and using messages for AI features,” WhatsApp wrote in a blog post last week. Like disappearing messages, anyone in a chat can turn Advanced Chat Privacy on and off—which is recorded for all to see—so participants just need to be mindful of any adjustments.

Private Processing is built with special hardware that isolates sensitive data in a “Trusted Execution Environment,” a siloed, locked-down region of a processor. The system is built to process and retain data for the minimum amount of time possible and is designed grind to a halt and send alerts if it detects any tampering or adjustments. WhatsApp is already inviting third-party audits of different components of the system and will make it part of the Meta bug bounty program to encourage the security community to submit information about flaws and potential vulnerabilities. Meta also says that, ultimately, it plans to make the components of Private Processing open source, both for expanded verification of its security and privacy guarantees and to make it easier for others to build similar services.

Last year, Apple debuted a similar scheme, known as Private Cloud Compute, for its Apple Intelligence AI platform. And users can turn the service on in Apple’s end-to-end encrypted communication app, Messages, to generate message summaries and compose “Smart Reply” messages on both iPhones and Macs.

Looking at Private Cloud Compute and Private Processing side by side is like comparing, well, Apple(s) and oranges, though. Apple’s Private Cloud Compute underpins all of Apple Intelligence everywhere it can be applied. Private Processing, on the other hand, was purpose-built for WhatsApp and doesn’t underpin Meta’s AI features more broadly. Apple Intelligence is also designed to do as much AI processing as possible on-device and only send requests to the Private Cloud Compute infrastructure when necessary. Since such “on device” or “local” processing requires powerful hardware, Apple only designed Apple Intelligence to run at all on its recent generations of mobile hardware. Old iPhones and iPads will never support Apple Intelligence.

Apple is a manufacturer of high-end smartphones and other hardware, while Meta is a software company, and has about 3 billion users who have all types of smartphones, including old and low-end devices. Rohlf and Colin Clemmons, one of the Private Processing lead engineers, say that it wasn’t feasible to design AI features for WhatsApp that could run locally on the spectrum of devices WhatsApp serves. Instead, WhatsApp focused on designing Private Processing to be as unhelpful as possible to attackers if it were to be breached.

“The design is one of risk minimization,” Clemmons says. “We want to minimize the value of compromising the system.”

The whole effort raises a more basic question, though, about why a secure communication platform like WhatsApp needs to offer AI features at all. Meta is adamant, though, that users expect the features at this point and will go wherever they have to to get them.

“Many people want to use AI tools to help them when they are messaging,” WhatsApp head Will Cathcart told WIRED in an email. “We think building a private way to do that is important, because people shouldn’t have to switch to a less-private platform to have the functionality they need.”

“Any end-to-end encrypted system that uses off-device AI inference is going to be riskier than a pure end to end system. You’re sending data to a computer in a data center, and that machine sees your private texts,” says Matt Green, a Johns Hopkins cryptographer who previewed some of the privacy guarantees of Private Processing, but hasn’t audited the complete system. “I believe WhatsApp when they say that they’ve designed this to be as secure as possible, and I believe them when they say that they can’t read your texts. But I also think there are risks here. More private data will go off device, and the machines that process this data will be a target for hackers and nation state adversaries.”

WhatsApp says, too, that beyond basic AI features like text summarization and writing suggestions, Private Processing will hopefully create a foundation for expanding into more complicated and involved AI features in the future that involve processing, and potentially storing, more data.

As Green puts it, “Given all the crazy things people use secure messengers for, any and all of this will make the Private Processing computers into a very big target.”

WhatsApp Is Walking a Tightrope Between AI Features and Privacy

Researchers reveal a collection of bugs known as AirBorne that would allow any hacker on the same Wi-Fi network as a third-party AirPlay-enabled device to surreptitiously run their own code on it.

Apple’s AirPlay feature enables iPhones and Macbooks to seamlessly play music or show photos and videos on other Apple devices or third-party speakers and TVs that integrate the protocol. Now newly uncovered security flaws in AirPlay mean that those same wireless connections could allow hackers to move within a network just as easily, spreading malicious code from one infected device to another. Apple products are known for regularly receiving fixes, but given how rarely some smart-home devices are patched, it’s likely that these wirelessly enabled footholds for malware, across many of the hundreds of models of AirPlay-enabled devices, will persist for years to come.

On Tuesday, researchers from the cybersecurity firm Oligo revealed what they’re calling AirBorne, a collection of vulnerabilities affecting AirPlay, Apple’s proprietary radio-based protocol for local wireless communication. Bugs in Apple’s AirPlay software development kit (SDK) for third-party devices would allow hackers to hijack gadgets like speakers, receivers, set-top boxes, or smart TVs if they’re on the same Wi-Fi network as the hacker’s machine. Another set of AirBorne vulnerabilities would have allowed hackers to exploit AirPlay-enabled Apple devices too, Apple told Oligo, though these bugs have been patched in updates over the last several months, and Apple tells WIRED that those bugs could have only been exploited when users changed default AirPlay settings.

Those Apple devices aside, Oligo’s chief technology officer and cofounder, Gal Elbaz, estimates that potentially vulnerable third-party AirPlay-enabled devices number in the tens of millions. “Because AirPlay is supported in such a wide variety of devices, there are a lot that will take years to patch—or they will never be patched,” Elbaz says. “And it's all because of vulnerabilities in one piece of software that affects everything.”

Despite Oligo working with Apple for months to patch the AirBorne bugs in all affected devices, the Tel-Aviv-based security firm warns that the AirBorne vulnerabilities in many third-party gadgets are likely to remain hackable unless users act to update them. If a hacker can get onto the same Wi-Fi network as those vulnerable devices—whether by hacking into another computer on a home or corporate network or by simply connecting to the same coffeeshop or airport Wi-Fi—they can surreptitiously take over these gadgets. From there, they could use this control to maintain a stealthy point of access, hack other targets on the network, or add the machines to a botnet of infected, coordinated machines under the hacker’s control.

Oligo also notes that many of the vulnerable devices have microphones and could be turned into listening devices for espionage. The researchers did not go so far as to create proof-of-concept malware for any particular target that would demonstrate that trick.

Oligo says it warned Apple about its AirBorne findings in the late fall and winter of last year, and Apple responded in the months since then by pushing out security updates. The researchers collaborated with Apple to test and validate the fixes for Macs and other Apple products.

Apple tells WIRED that it has also created patches that are available for impacted third-party devices. The company emphasizes, though, that there are limitations to the attacks that would be possible on AirPlay-enabled devices as a result of the bugs, because an attacker must be on the same Wi-Fi network as a target to exploit them. Apple adds that while there is potentially some user data on devices like TVs and speakers, it is typically very limited.

Below is a video of the Oligo researchers demonstrating their AirBorne hacking technique to take over an AirPlay-enabled Bose speaker to show their company’s logo for AirBorne. (The researchers say they didn’t intend to single out Bose, but just happened to have one of the company’s speakers on hand for testing.) Bose did not immediately respond to WIRED’s request for comment.

The AirBorne vulnerabilities Oligo found also affect CarPlay, the radio protocol used to connect to vehicles’ dashboard interfaces. Oligo warns that this means hackers could hijack a car’s automotive computer, known as its head unit, in any of more than 800 CarPlay-enabled car and truck models. In those car-specific cases, though, the AirBorne vulnerabilities could only be exploited if the hacker is able to pair their own device with the head unit via Bluetooth or a USB connection, which drastically restricts the threat of CarPlay-based vehicle hacking.

The AirPlay SDK flaws in home media devices, by contrast, may present a more practical vulnerability for hackers seeking to hide on a network, whether to install ransomware or carry out stealthy espionage, all while hiding on devices that are often forgotten by both consumers and corporate or government network defenders. “The amount of devices that were vulnerable to these issues, that's what alarms me,” says Oligo researcher Uri Katz. “When was the last time you updated your speaker?”

The researchers originally started thinking about this property of AirPlay, and ultimately discovered the AirBorne vulnerabilities, while working on a different project analyzing vulnerabilities that could allow an attacker to access internal services running on a target’s local network from a malicious website. In that earlier research, Oligo’s hackers found they could defeat the fundamental protections baked into every web browser that are meant to prevent websites from having this type of invasive access on other people’s internal networks.

While playing around with their discovery, the researchers realized that one of the services they could access by exploiting the bugs without authorization on a target’s systems was AirPlay. The crop of AirBorne vulnerabilities revealed today is unconnected to the previous work, but was inspired by AirPlay’s properties as a service built to sit open and at the ready for new connections.

And the fact that the researchers found flaws in the AirPlay SDK means that vulnerabilities are lurking in hundreds of models of devices—and possibly more, given that some manufacturers incorporate the AirPlay SDK without notifying Apple and becoming “certified” AirPlay devices.

“When third-party manufacturers integrate Apple technologies like AirPlay via an SDK, obviously Apple no longer has direct control over the hardware or the patching process,” says Patrick Wardle, CEO of the Apple device-focused security firm DoubleYou. “As a result, when vulnerabilities arise and third-party vendors fail to update their products promptly—or at all—it not only puts users at risk but could also erode trust in the broader Apple ecosystem."

Millions of Apple Airplay-Enabled Devices Can Be Hacked via Wi-Fi

Records reviewed by WIRED show law enforcement agencies are eager to take advantage of the data trails generated by a flood of new internet-connected vehicle features.

Automakers are increasingly pushing consumers to accept monthly and annual fees to unlock preinstalled safety and performance features, from hands-free driving systems and heated seats to cameras that can automatically record accident situations. But the additional levels of internet connectivity this subscription model requires can increase drivers’ exposure to government surveillance and the likelihood of being caught up in police investigations.

A cache of more than two dozen police records recently reviewed by WIRED show US law enforcement agencies regularly trained on how to take advantage of “connected cars,” with subscription-based features drastically increasing the amount of data that can be accessed during investigations. The records make clear that law enforcement’s knowledge of the surveillance far exceeds that of the public and reveal how corporate policies and technologies—not the law—determine driver privacy.

“Each manufacturer has their whole protocol on how the operating system in the vehicle utilizes telematics, mobile Wi-Fi, et cetera,” one law enforcement officer noted in a presentation prepared by the California State Highway Patrol (CHP) and reviewed by WIRED. The presentation, while undated, contains statistics on connected cars for the year 2024. “If the vehicle has an active subscription,” they add, “it does create more data.”

The CHP presentation, obtained by government transparency nonprofit Property of the People via a public records request, trains police on how to acquire data based on a variety of hypothetical scenarios, each describing how vehicle data can be acquired based on the year, make, and model of a vehicle. The presentation acknowledges that access to data can ultimately be limited due to choices made by not only vehicle manufacturers but the internet service providers on which connected devices rely.

One document notes, for instance, that when a General Motors vehicle is equipped with an active OnStar subscription, it will transmit data—revealing its location—roughly twice as often as a Ford vehicle. Different ISPs appear to have not only different capabilities but policies when it comes to responding to government requests for information. Police may be able to rely on AT&T to help identify certain vehicles based on connected devices active in the car but lack the ability to do so when the device relies on a T-Mobile or Verizon network instead.

Charlotte McCoy, a GM spokesperson, tells WIRED the company now requires a court order before handing over location data to law enforcement. “We review each request individually to assess the circumstances and the nature of the request before providing any information,” they say. “Connectivity offers many benefits—including navigation, communication, safety, and maintenance—and customers can mask their location or turn off connectivity at any time.”

Other car manufacturers listed in the CHP presentation, including Ford, did not respond to a request for comment.

“There's definitely a role being played by the companies in deciding what kind of standard they're going to insist on,” says Andrew Crocker, the surveillance litigation director at the Electronic Frontier Foundation. “And this is a dynamic we've seen in other areas of tech. Google and Facebook and Apple all played a role in saying, ‘We'll only provide this data in response to a warrant; other data we'll provide in response to a subpoena.’”

When police are investigating a specific suspect, they will often use a technique known as a “ping” to geographically locate a specific device known to belong to that individual. But when canvassing near a crime scene for an unknown perpetrator, authorities commonly rely on a procedure known as a “tower dump,” requesting that ISPs cast a wider net and identify virtually any devices that have connected to a specific cell tower during a certain window of time. Police analysts can then comb through this data and attempt to identify a culprit, often using surveillance footage or witness testimony about a vehicle’s color, make, or model.

Nearly all subscription-based car features rely on devices that come preinstalled in a vehicle, with a cellular connection necessary only to enable the automaker's recurring-revenue scheme. The ability of car companies to charge users to activate some features is effectively the only reason the car’s systems need to communicate with cell towers. The police documents note that companies often hook customers into adopting the services through free trial offers, and in some cases the devices are communicating with cell towers even when users decline to subscribe.

In an August 2022 email, one detective noted: “In some vehicles, again \[it\] depends on manufacturer, the vehicle is still doing this despite the lack of an active subscription, and just sending the data back to the mother ship. This could be due to collecting user data for what the manufacturer sells it for, to providing this data to try to sell you on renewing your \[subscription\] package that lapsed.”

The “tower dump” technique is becoming increasingly unpopular in US courts following the US Supreme Court’s acknowledgement in 2018 that location data raises significant Fourth Amendment concerns. While the Supreme Court specifically avoided addressing tower dumps in its landmark _US v. Carpenter_ decision, a Fifth Circuit ruling last year placed the capability in great jeopardy, concluding that a warrant to “geofence” an area and collect evidence from a wide variety of individuals is inherently unconstitutional.

On the back of that decision, a federal magistrate in Mississippi ruled two months ago that tower dumps are likewise unconstitutional. While a “tower dump” and a “geofence” are not precisely the same—the latter relying on GPS coordinates obtained from internet companies such as Google, as opposed to a cell tower—the results are more or less identical: offering police a dragnet with which to accumulate vast amounts of location data on individuals, many if not most of whom are not suspected of committing a crime.

In response to the rapid changes in case law surrounding location data, Google—historically a frequent target of geofence warrants—announced technical changes to its software last year, making it effectively impossible to respond to these types of warrants.

“Location data is some of the most sensitive, revealing information that is generated by our devices, including our cars,” the EFF’s Crocker says. “It's extremely revealing of obviously where you go and where you've been, but also all the people you associate with and all the things you're doing. You can paint a very clear picture of someone's life with just a list of all the places they've been in their car. The Supreme Court has made that very clear.”

The police documents reviewed by WIRED alone demonstrate the arbitrary nature of vehicle surveillance upon this shifting legal landscape, with police noting, for instance, that while Verizon will refuse to allow police to define their own radius when requesting cell tower data, its competitors impose no such limitations. Another document notes that while AT&T will conduct “pings,” locating a device in real time, it will only do so for “voice devices.”

What is also clear from the documents is that US police are aware of the control corporations have over their ability to acquire vehicle location data, expressing fears that they could abruptly decide to kill off certain capabilities at any time.

In a letter sent in April 2024 to the Federal Trade Commission, US senators Ron Wyden and Edward Markey—Democrats from Oregon and Massachusetts, respectively—noted that a range of automakers, from Toyota, Nissan, and Subaru, among others, are willing to disclose location data to the government in response to a subpoena without a court order. Volkswagen, meanwhile, had its own arbitrary rules, limiting subpoenas to fewer than seven days’ worth of data. The senators noted that these policies stood in contrast to public pledges previously made by some automakers to require a warrant or court order before surrendering a customer’s location data.

Automakers “differ significantly on the important issue of whether customers are ever told they were spied on,” the senators wrote. At the time of the letter, only Tesla had a policy, they said, of informing customers about legal demands. “The other car companies do not tell their customers about government demands for their data, even if they are allowed to do so.”

“We respect our customers’ privacy and take our responsibility to protect their personal information seriously,” Bennet Ladyman, a T-Mobile spokesperson, says.

AT&T spokesperson Jim Kimberly says: “Like all companies, we are required by law to provide information to law enforcement and other government entities by complying with court orders, subpoenas, and other lawful discovery requests. In all cases, we review requests to determine whether they are valid. We require a search warrant based on the probable-cause standard for all government demands for real-time or historical location information, except in emergency situations. For government demands for cell tower searches, we require a probable-cause search warrant or a court order, except in emergency situations.”

Verizon did not respond to a request for comment.

“Especially now, with American civil liberties eroding rapidly, people should exercise great caution in granting new surveillance powers to law enforcement,” says Ryan Shapiro, executive director of Property of the People.

Jay Stanley, a senior policy analyst at the American Civil Liberties Union, notes that the police documents reviewed by WIRED contained substantial detail about car surveillance that appear to be publicly unavailable, suggesting that corporations are being far more open with law enforcement than they are with their own customers.

“It's an ongoing scandal that this kind of surveillance is taking place without people being aware of it, let alone giving permission for it,” Stanley says. “If they're carrying out surveillance on the public, the public should know. They should have meaningful knowledge and give meaningful consent before any kind of surveillance is activated, which clearly is not the case.”

Car Subscription Features Raise Your Risk of Government Surveillance, Police Records Show

Plus: Cybercriminals stole a record-breaking fortune from US residents and businesses in 2024, and Google performs its final flip-flop in its yearslong quest to kill tracking cookies.

As the Trump administration’s aggressive immigration policy ramps up, people have started to seriously consider their privacy and security when crossing into the United States. That’s especially true when it comes to searches of travelers’ phones and other devices, which US Customs and Border Protection agents have broad authority to search. Fortunately, there are some steps you can take, such as deleting certain apps from your personal phone or using an alternative phone that’s set up just for traveling internationally.

Operatives with Elon Musk’s so-called Department of Government Efficiency (DOGE) have spent the first months of the Trump administration clawing their way into US government systems. It’s now starting to become clear exactly what those systems are and what kind of data on US residents they hold. WIRED this week detailed the 19 systems DOGE operatives have access to just at the Department of Health and Human Services.

Pope Francis died on Monday at age 88. The passing of the supreme pontiff sets in motion a conclave, the secretive process used to select the new pope. To protect the conclave’s integrity and try to prevent leaks, a wide range of security measures will be put in place, from privacy film on windows at the Vatican to signal jammers and sweeps for hidden microphones.

Google recently announced the initial rollout of end-to-end encrypted email for Google Workspace accounts, which is good news for the privacy of enterprise-level users. When a Workspace user emails a non-Workspace account, the recipient gets an invitation to create a guest account so they can read the email. Unfortunately, security experts say, this will likely create new opportunities for phishing attacks, as scammers try to bait people with fake invitations.

But that’s not all. Each week, we round up the security and privacy news we didn’t cover in depth ourselves. Click the headlines to read the full stories. And stay safe out there.

SignalGate is the scandal that just won’t die—at least not if you’re US secretary of defense Pete Hegseth. On Wednesday, The Washington Post reported that Hegseth had installed Signal on a “second computer in his office” so that he could “use Signal in a classified space, where his cellphone and other personal electronics are not permitted, and communicate with ease with anyone.”

The Associated Press on Thursday added to the picture of Hegseth’s reported Signal use, revealing that Hegseth got a second internet line installed that connected directly to the public internet rather than through the Pentagon’s secured connection, according to sources who spoke with the AP. Hegseth allegedly did this so he could use that second computer with Signal installed. Then on Friday, The New York Times found that the phone number associated with Hegseth’s Signal account—the one he used in that infamous group chat—is easily discoverable online, potentially opening him up to targeted cyberattacks by hostile nations.

**Cybercriminals Stole a Record-Breaking $16.6 Billion From US Entities in 2024**

Despite a steady flow of arrests and takedowns of online scammers, cybercriminals are operating at unprecedented levels and making more money than ever. Two reports released this week reveal the stark scale of online criminality. Last year in the United States, businesses and individuals lost $16.6 billion to online crimes, according to the FBI’s Internet Crime Complaint Center—that’s the highest figure ever reported and a leap of 33 percent compared to 2023. In 2024, there were 859,532 complaints about potential online crimes, with the FBI saying phishing and spoofing complaints account for 193,000 of them, followed by extortion with 86,000 complaints. Investment scams, which often involve cryptocurrency, made up more than $6 billion of the total losses, with business email compromise scams leading to losses of $2.7 billion.

Around the same time, the United Nations Office on Drugs and Crime highlighted that giant scam compounds in Southeast Asia—where human trafficking victims are forced to work scamming people—are generating $40 billion in profits per year and keep on growing. These industrial-scale scam organizations, which are often linked to Chinese criminals, heavily use investment scams (sometimes called pig-butchering) to con people out of their life savings and are expanding outside of the region. “It spreads like a cancer,” Benedikt Hofmann of the UNODC said in a statement.

**Google Chrome Won’t Ditch Creepy Tracking Cookies After All**

Back in 2020, Google announced its Chrome browser would stop using third-party cookies, which track people around the web, and would move to a less creepy way of powering its advertising businesses. Web browsers such as Safari, Firefox, and Brave ditched cookies years before Google made the announcement. But this week, after countless U-turns, failed efforts to develop alternatives, and criticism that proposals to replace cookies would favor Google, the company announced it will, in fact, keep the trackers in Chrome.

“We’ve made the decision to maintain our current approach to offering users third-party cookie choice in Chrome,” wrote Anthony Chavez, the Google VP in charge of its Privacy Sandbox efforts, in a blog post. “As we’ve engaged with the ecosystem, including publishers, developers, regulators, and the ads industry, it remains clear that there are divergent perspectives on making changes that could impact the availability of third-party cookies,” Chavez wrote. While the US government is proposing that Google sell off Chrome as part of its antitrust case against the company, it’s still possible to turn off third-party cookies or use a privacy-friendly browser instead.

Protecting Your Phone—and Your Privacy—at the US Border

Google is rolling out an end-to-end encrypted email feature for business customers, but it could spawn phishing attacks, particularly in non-Gmail inboxes.

Google announced at the beginning of April that it is launching a streamlined tool that will allow business users to easily send “end-to-end encrypted” emails—an effort to address the longstanding challenge of adding additional security protections to email messages. The feature is currently in beta for enterprise users to try out within their own organization. It will then expand to allow Google Workspace users to send end-to-end encrypted emails to any Gmail user. By the end of the year, the feature will allow Workspace users to send the more secure emails to any inbox. Email spam and digital fraud researchers warn, though, that while the feature will provide a new option for email privacy and security, it will also inevitably spawn new phishing attacks.

End-to-end encryption is a protection that keeps data scrambled at all times except on the sender and recipient's devices, and it is difficult to add to the historic email protocol. Mechanisms to do it are typically very complicated and costly to implement and only make sense for large organizations trying to meet specific compliance requirements. In contrast, Google's end-to-end encrypted email tool is simple to use and doesn't require significant IT overhead. The scenario that digital fraud researchers are most concerned about, though, relates to the case where a Workspace user sends an end-to-end encrypted email to a non-Gmail user.

“When the recipient is not a Gmail user, Gmail sends them an invitation to view the E2EE email in a restricted version of Gmail,” Google wrote in a blog post. “The recipient can then use a guest Google Workspace account to securely view and reply to the email.”

The fear is that scammers will take advantage of this new and more secure communication mechanism by creating fake copies of these invitations that contain malicious links, and prompt targets to enter their login credentials for their email, single sign-on services, or other accounts.

“Looking at Google's implementation, we can see it introduces a new workflow for non-Gmail users—receiving a link to view an email,” says Jérôme Segura, senior director of threat intelligence at Malwarebytes. “Users might not yet be familiar with exactly what a legitimate invitation looks like, making them more susceptible to clicking on a fake one.”

Given email's technical limitations, Google created a way for an organization's Workspace to automatically manage keys—used to descramble encrypted messages. Key management is what makes end-to-end encrypting email so difficult, so offering a solution that is easy for customers is a departure from what's currently available. The fact that the organization's Workspace controls the keys rather than storing them locally on a sender and recipient's devices does mean that the feature doesn't quite qualify as end-to-end encryption in the strictest sense of the term. But researchers say that for use cases like business compliance, the tool could still be extremely useful. And individuals who want end-to-end encrypted communications should just use a purpose-built app like Signal.

When Gmail users receive one of the new encrypted emails from a Google Workspace user, Google's extensive array of dynamic spam filters and fraud detection mechanisms will be in play to protect against spam, phishing, and rogue imposters broadly. But email users outside the Google ecosystem will also be able to receive encrypted email invitations, which makes the service available to anyone, but also will leave non-Google users to their own devices.

Scammers will prey on anything topical to generate new scams, and this threat certainly isn't unique to Google's new encrypted email feature. The invitations to view end-to-end encrypted emails will come with a warning that says, “Be careful when signing in to view this encrypted message. This message is from an external sender and is encrypted. Make sure you trust the sender and their identity provider before entering your username and password.”

“While it’s absolutely true that scammers are always looking for new ways to abuse any product, we built this particular technology with this risk in mind,” Google spokesperson Ross Richendrfer said in a statement. “The notifications users will receive in this case are very similar to Drive file sharing notifications that go out whenever someone shares a doc or file. All the protections we employ to keep scammers from capitalizing on these messages will help us protect this new class of notifications as well.”

Generations of Google Drive and Google Docs scams show, though, that it is particularly difficult to combat imposter invitations outside of Google's ecosystem. But when it comes to the new end-to-end encrypted email feature, “it was either adding a warning or not allowing this feature for non-Gmail users,” Malwarebytes's Segura says.

In fact, the new tool may offer particularly good fodder for scammers, given that Google is such a trusted organization, and targets may have heard about how end-to-end encryption is a special, gold-standard security feature.

“It's almost as if someone at Google knew this was a bad idea and asked for a warning to be added,” Malwarebytes’ Segura says. “It's quite likely fraudsters will jump on the opportunity to craft phishing emails using this exact same template, even including the original warning that will be overlooked.”

Gmail’s New Encrypted Messages Feature Opens a Door for Scams

Following the death of Pope Francis, the Vatican is preparing to organize a new conclave in less than 20 days. This is how they’ll tamp down on leaks.

In 2005, cell phones were banned for the first time during the conclave, the process by which the Catholic Church elects its new pope. Twenty years later, after the death of Pope Francis, the election process is underway again. Authorities have two priorities: to protect the integrity of those attending the meeting, and to ensure that it proceeds in strict secrecy (under penalty of excommunication and imprisonment) until the final decision is made.

By 2025, the Gendarmerie corps guarding Vatican City faces unprecedented technological challenges compared to other conclaves. Among them are artificial intelligence systems, drones, military satellites, microscopic microphones, a misinformation epidemic, and a world permanently connected and informed through social media.

The conclave is scheduled to take place approximately 20 days after the pope's death. The Vatican and the Holy See are preparing for the arrival of the cardinals who will vote for the next leader of the Catholic faith. Emergency and control bodies are also working on it with state-of-the-art technology. So far, they have not shared details about their security arrangements, but they are not inexperienced in the task of safeguarding the integrity of high-profile figures in the face of today's technological risks.

In fact, the election in 2013 of Jorge Mario Bergoglio—the real name of Pope Francis—as supreme pontiff gives some indications of the rigorous security strategies that will be presented in the next conclave.

**Signal Jammers and Device Checks**

The Vatican has internet access, but within the areas where the cardinals will reside and vote for the new pope, there will be signal jammers. The technology prevents two devices from communicating with each other through radio frequency interference. The headquarters becomes an electronic bunker. Thus, if someone were to manage to introduce a microphone, telephone, or computer, they would be unable to transmit information.

However, the possibility of administrative staff or the cardinals themselves introducing technology is remote. Authorities inspect the building for days in search of unauthorized microphones or cameras, check every permitted attendee, and double-check participants.

**Privacy Film in the Windows**

Contemporary satellites are capable of taking pictures of people's faces from space, while AI can interpret lip movements. However, since there's currently no technology to see through walls with such high resolution, the best strategy against espionage in the conclave is to close doors and windows.

During meetings and in the sleeping quarters, voters are not allowed to look outside. In addition, before the cardinals arrive, Vatican staff place opaque film over windows so that no journalist, satellite, or drone can take pictures of the interior.

**Locked-Down Vatican**

The Vatican covers only 0.44 square kilometer in area. It is the smallest nation in the world. Until 2018, it had 650 cameras monitoring its streets from an underground command center. In addition, the Vatican City Gendarmerie, which functions as a conventional police force, and the Pontifical Swiss Guard, which acts as an army, are located within the territory. While in photographs they appear to be wearing antique costumes and carrying halberds, the latter group has highly trained personnel with heavy weapons, such as machine guns, rifles, and explosives.

An estimated 200,000 people are expected to be present in the small city-state once the conclave has determined the name of Pope Francis' successor.

The Tech That Safeguards the Conclave’s Secrecy

Customs and Border Protection has broad authority to search travelers’ devices when they cross into the United States. Here’s what you can do to protect your digital life while at the US border.

Entering the United States has become more precarious since the start of the second Trump administration in January. There has been an apparent surge in both foreign visitors and US visa holders being detained, questioned, and even deported at the border. As the situation evolves, demand for flights from Canada and Europe has plummeted as people reevaluate their travel plans.

Many people, though, can’t avoid border crossings, whether they are returning home after traveling for work or visiting friends and family abroad. Regardless of the reason for travel, US Customs and Border Protection (CBP) officials have the authority to search people’s phones and other devices as they determine who is allowed to enter the country. Multiple travelers have reported being questioned or turned away at the US border in recent weeks in relation to content on their phones.

While not unique to the US border—other nations also have powers to inspect phones—the increasingly volatile nature of the Trump administration’s border policies is causing people to rethink the risks of carrying devices packed with personal information to and from the US. Canadian authorities have updated travel guidance to warn of phone searches and seizures, some corporate executives are reconsidering the devices they carry, some officials in Europe continue to receive burner phones for certain trips to the US, and the Committee to Protect Journalists has warned foreign reporters about device searches at the US border.

With this in mind, here’s the WIRED guide to planning for bringing a smartphone across the border. You should also use WIRED’s guide to entering the US with your digital privacy intact to get a broader view of how to minimize data and take precautions. But start here for everything smartphone.

**What Can CBP Access?**

Do CBP officials have the authority to search your phone at the border? The short answer is yes. Searches are either manual, with a border official looking through the device, or more advanced, involving forensic tools to extract data en masse. To get into your phone, border officials can ask for your PIN or biometric to unlock the phone. However, your legal status and right to enter the US will make a difference in what a search might look like at the border.

Generally, border zones—which includes US international airports—fall outside of Fourth Amendment protections that require a warrant for a device to be searched (though one federal court has ruled otherwise). As such, CBP has the power to search any traveler’s phone or other electronic devices, such as computers and cameras, when they’re entering the country. US citizens and green card holders can refuse a device search without being denied entry, but they may face additional questioning or temporary device seizure. And as the Trump administration pushes the norms of acceptable government conduct, it is possible that, in practice, green card holders could face new repercussions for declining a device search. US visa holders and foreign visitors can face detention and deportation for refusing a device search.

“Not everybody has the same risk profile,” says Molly Rose Freeman Cyr, a member of Amnesty International’s Security Lab. “A person’s legal status, the social media accounts that they use, the messaging apps that they use, and the contents of their chats” should all factor into their risk calculus and the decisions they make about border crossings, Cyr says.

If you feel safe refusing a search, make sure to disable biometrics used to unlock your device, like face or fingerprint scanners, which CBP officers can use to access your device. Instead, use only a PIN or an alphanumeric code (if available on your device). Make sure to keep your phone’s operating system up to date, which can make it hard to crack with forensic tools.

You should also consider factors like nationality, citizenship, profession, and geopolitical views in assessing whether you or someone you’re traveling with could be at higher risk of scrutiny during border crossings.

In short, you need to make some decisions before you travel about whether you would be prepared to refuse a device search and whether you want to make changes to your devices before your trips.

Keep in mind that there are simple steps anyone can take to keep your devices out of sight and, hopefully, out of mind during border crossings. It’s always a good idea to obtain a printed boarding pass or prepare other paper documents for review and then turn your phone off and store it in your bag before you approach a CBP agent.

**Traveling With an Alternate Phone**

There are two ways to approach device privacy for border crossings. One is to start with a clean slate, purchasing a phone for the purpose of traveling or wiping and repurposing your old phone—if it still receives software updates.

The device doesn’t need to be a true “burner” phone, in the sense that you will be carrying it with you as if nothing is out of the ordinary, so you don’t need to purchase it with cash or take other steps to ensure that it can’t be connected to you. The idea, though, is to build a sanitized version of your digital life on the travel phone, ideally with separate communication and social media accounts created specifically for travel. This way, if your device is searched, it won’t have the back catalog of data—old text messages, years of photos, forgotten apps, and access to many or all of your digital accounts—that exists on your primary phone and could reveal details of your political views, your associations, or your movements over time.

Starting with a clean slate makes it easy to practice “data minimization,” or reducing the data available to another person: Simply put the things you’ll need for a trip on the phone without anything you won’t need. You might make a travel email address, some alternate social media accounts, and a separate account for end-to-end encrypted communications using an app like Signal or WhatsApp. Ideally you would totally silo your real digital life from this travel life. But you can also include some of your regular personal apps, building back from the ground up while determining on a selective basis whether you have existing accounts that you feel comfortable potentially exposing. Perhaps, for example, you think that showing a connection to your employer or a community organization could be advantageous in a fraught situation.

Privacy and digital rights advocates largely prefer the approach of building a travel device from scratch, but they caution that a phone that is too squeaky clean, too much like a burner phone, can arouse suspicion.

“You have to ‘seed’ the device. Use the phone for a day or even for a few hours. It just can't be _clean_ clean. That’s weird,” says Matt Mitchell, founder of CryptoHarlem, a security and privacy training and advocacy nonprofit. “My recommendation is to make a finsta for travel, because if they ask you what your profile is, how are you gonna say ‘I don't use any social media’? Many people have a few accounts anyway. One ratchet, one wholesome—add one travel.”

Cyr, from Amnesty International, also points out that a true burner phone would be a “dumb” phone, which wouldn’t be able to run apps for encrypted communications. “The advantage that we all have with smartphones is that you can communicate in an encrypted way,” Cyr says. “People should be conscious that any nonencrypted communication is less secure than a phone call or a message on an application like Signal.”

While a travel device doesn’t need to use a prepaid SIM card bought with cash, it should not share your normal phone number, since this number is likely linked to most if not all of your key digital accounts. Buy a SIM card for your trip or only use the device on Wi-Fi.

**Traveling With Your Primary Phone**

The other approach you can take to protecting your device during border crossings is to modify your primary smartphone before travel. This involves removing old photos and messages and storing them somewhere else, cleaning out nonessential apps, and either removing some apps altogether or logging out of them with your main accounts and logging back in with travel accounts.

Mohammed Al-Maskati, digital security helpline director at the rights group Access Now, says that people should consider this type of clean-out before they travel. “I will look at my device and see what apps I need,” he says. “If I don't need the app, I just remove it.”

Al-Maskati adds that he suggests people particularly remember to remove dating apps and anything related to LGBTQI communities, especially if they consider themselves to be at higher risk of facing a device search. And generally, this approach is only safe if you are particularly diligent about removing every app that might expose you to risk.

You could use your own phone as a travel phone by backing it up, wiping it, building a travel device with only the apps you really need while traveling, going on your trip, and then restoring from the backup when you get home. This approach is doable but time consuming, and it creates more opportunities for operational security mistakes or what are known as “opsec fails.” If you try to delete all of your old, unwanted apps, but miss one, you could end up exposing an old social media account or other historic service that has forgotten data in it. Messaging apps can have easily searchable archives going back years and can automatically save photos and files without you realizing it. And if you back up all of your data to the cloud and take it off your device, but are still logged into the cloud account underpinning other services (like your main Google or Apple account), you could be asked to produce the data from the cloud for inspection.

Still, if you assess that you are at low risk of facing scrutiny during a border crossing or you don’t have access to an additional device for travel, modifying your main smartphone is a good option. Just be careful.

**What To Do, If Nothing Else**

Given all of this, you may be hyped up and ready to throw your phone in the ocean. Or you may be thinking there’s no way in hell that you’re ever going to take the time to deal with any of this. For those in the latter camp, you’ve come this far, so don’t click away just yet. If you don’t want to take the time to make a bunch of changes, and you don’t think you’re at particular risk during border crossings (though keep in mind that it’s possible your risk is higher than you realize), there are still a few easy things you can do to protect your digital privacy that are better than nothing.

First, as mentioned above, print a paper boarding pass and any other documents you might need. Even if you don’t turn your phone off and stow it in a bag for your entire entry or exit process, you can put it in your pocket and have your paper ticket and other documents ready while actually interacting with agents. And taking basic digital hygiene steps, like updating your phone and removing apps and data you no longer need, can go a long way.

“We all need to be recognizing that authorities may scrutinize your online presence, including social media activity and posts you’ve published,” says Danacea Vo, founder of Cyberlixir, a cybersecurity provider for nonprofits and vulnerable communities. “Since people have gotten more vocal on social media, they’re very worried about this. Some have even decided not to risk traveling to or from the US this year.”

Just three months into the Trump administration's promised crackdown on immigration to the United States, Immigrations and Customs Enforcement now has a $30 million contract with Palantir to build a “near-real time” surveillance platform called ImmigrationOS that would track information about people self-deporting (electing to leave the US). Meanwhile, the Department of Homeland Security has been sending aggressive emails telling people with temporary legal status to leave the US. It is unclear who has actually been sent the messages, though, given that a number of people who are US-born citizens have reported receiving them.

The US Cybersecurity and Infrastructure Security Agency briefly seemed poised this week to cancel funding for the critical software vulnerability tracking project known as the CVE Program. CISA eventually came through with the funding, but some members of the CVE Program's governing board are planning to make the project into an independent nonprofit.

A lawsuit over the Trump administration’s Houthi Signal group chat is revealing details on steps that federal departments did—and did not—take to preserve the messages per records laws.

**Draft Legislation in Florida Explicitly Demands Encryption Backdoors**

A draft bill in the state of Florida would require social media companies to provide law enforcement with encryption backdoors so cops could access users’ accounts. The bill advanced unanimously from committee this week and will now go to the state Senate for a vote. If passed, the Social Media Use by Minors bill, which is sponsored by state senator Blaise Ingoglia, would require “social media platforms to provide a mechanism to decrypt end-to-end encryption when law enforcement obtains a subpoena.” The bill would also ban disappearing messages in accounts designed for children and would require social media companies to create a mechanism for parents or guardians to access children's accounts. Experts have long warned that encryption backdoors make everyone less secure, including those they are intended to help. Yet waves of attacks on encryption have repeatedly emerged over the years, including a recent trend in the European Union and United Kingdom.

**Judge Finds Broad Searches of Cell Tower Data Are Unconstitutional**

A Nevada district judge said this week that the practice of “tower dumps,” in which law enforcement pulls vast quantities of personal caller data from cell towers, violates the Fourth Amendment and is, thus, unconstitutional. Cell towers collect large quantities of information about users, including phone numbers and phone locations, so when cops request data from a tower during a specific time period, they often receive information on thousands of devices or more. In spite of the decision this week, though, Judge Miranda M. Du said that law enforcement could still use the evidence they had collected through a tower dump in their case.

**China Hits US With Accusations of Cyberattacks, Naming Alleged NSA Agents**

China claimed this week that the US National Security Agency perpetrated “advanced” cyberattacks against critical industries in February during the Asian Winter Games. Law enforcement from the northeastern city of Harbin put three alleged NSA agents—Katheryn A. Wilson, Robert J. Snelling, and Stephen W. Johnson—on a wanted list and claimed that the University of California and Virginia Tech were involved in the attacks. “We urge the US to take a responsible attitude on the issue of cyber security and … stop unprovoked smears and attacks on China,” ministry spokesperson Lin Jian said during a news briefing about multiple topics, according to Reuters. The US government frequently calls out Chinese state-backed hacking and names individual alleged perpetrators, but China has been less consistent about such statements. The move this week comes amid escalating tensions between the two countries, including the Trump's administration's trade war.

**US Customs and Border Protection Is Using a Number of AI Tools to Monitor Social Media**

CBP is using multiple artificial intelligence tools to scan social media and identify people of interest online, according to information from the agency and marketing materials reviewed by 404 Media from the contractors. CBP released information about the platforms this week in parallel to the US Department of Homeland Security’s announcement that it will “begin screening aliens’ social media activity for Antisemitism.” That statement also says that US Citizenship and Immigration Services is conducting “antisemitism” social media searches. CBP told 404 Media in an email that “neither tool is used for vetting or travel application processing,” referring to Dataminr and Onyx, but did not elaborate beyond that. The platforms use AI to parse large troves of data and can be used to develop leads on people who may be in violation of US immigration laws.
