This week on the Lock and Code podcast, we speak with Mallory Knodel about whether AI assistants are compatible with encrypted messaging apps.

_This week on the Lock and Code podcast…_

The era of artificial intelligence everything is here, and with it, come everyday surprises into exactly where the next AI tools might pop up.

There are major corporations pushing customer support functions onto AI chatbots, Big Tech platforms offering AI image generation for social media posts, and even Google has defaulted to include AI-powered overviews into everyday searches.

The next gold rush, it seems, is in AI, and for a group of technical and legal researchers at New York University and Cornell University, that could be a major problem.

But to understand their concerns, there’s some explanation needed first, and it starts with Apple’s own plans for AI.

Last October, Apple unveiled a service it is calling Apple Intelligence (“AI,” get it?), which provides the latest iPhones, iPads, and Mac computers with AI-powered writing tools, image generators, proof-reading, and more.

One notable feature in Apple Intelligence is Apple’s “notification summaries.” With Apple Intelligence, users can receive summarized versions of a day’s worth of notifications from their apps. That could be useful for an onslaught of breaking news notifications, or for an old college group thread that won’t shut up.

The summaries themselves are hit-or-miss with users—one iPhone customer learned of his own breakup from an Apple Intelligence summary that said: “No longer in a relationship; wants belongings from the apartment.”

What’s more interesting about the summaries, though, is how they interact with Apple’s messaging and text app, Messages.

Messages is what is called an “end-to-end encrypted” messaging app. That means that only a message’s sender and its recipient can read the message itself. Even Apple, which moves the message along from one iPhone to another, cannot read the message.

But if Apple cannot read the messages sent on its own Messages app, then how is Apple Intelligence able to summarize them for users?

That’s one of the questions that Mallory Knodel and her team at New York University and Cornell University tried to answer with a new paper on the compatibility between AI tools and end-to-end encrypted messaging apps.

Make no mistake, this research isn’t into whether AI is “breaking” encryption by doing impressive computations at never-before-observed speeds. Instead, it’s about whether or not the promise of end-to-end encryption—of confidentiality—can be upheld when the messages sent through that promise can be analyzed by separate AI tools.

And while the question may sound abstract, it’s far from being so. Already, AI bots can enter digital Zoom meetings to take notes. What happens if Zoom permits those same AI chatbots to enter meetings that users have chosen to be end-to-end encrypted? Is the chatbot another party to that conversation, and if so, what is the impact?

Today, on the Lock and Code podcast with host David Ruiz, we speak with lead author and encryption expert Mallory Knodel on whether AI assistants can be compatible with end-to-end encrypted messaging apps, what motivations could sway current privacy champions into chasing AI development instead, and why these two technologies cannot co-exist in certain implementations.

> “An encrypted messaging app, at its essence is encryption, and you can’t trade that away—the privacy or the confidentiality guarantees—for something else like AI if it’s fundamentally incompatible with those features.”

Tune in today to listen to the full conversation.

 The new rules for AI and encrypted messaging, with Mallory Knodel (Lock and Code S06E01) 

Smishing messages that come with instructions to bypass iMessage's protection against links are on the rise

A smishing (SMS phishing) campaign is targeting iMessage users, attempting to socially engineer them into bypassing Apple’s built in phishing protection.

For months, iMessage users have been posting examples online of how phishers are trying to get around this protection. And, now, the campign is gaining traction, according to our friends at BleepingComputer.

It works like this: Under normal circumstances, iMessage will disable all links in messages from unknown senders to protect the user against clicking them by accident. However, if a user replies to a message or adds the sender to their contact list, the links are enabled, allowing the person to click on the link.

The text of the messages comes in all the variations that phishers love to use:

*   Undeliverable packages from USPS, EVRI, Royal Mail, DHL, Fedex, etc.
*   Unpaid road toll.
*   Owed shipping fees.
*   Other outstanding payments that you are unaware of.

But they all end in a similar way to this:

> “(Please reply Y, then exit the SMS, re-open the SMS activation link, or copy the link to open in Safari)”

Replying with Y (or actually anything) will enable the links and turn off iMessage’s built-in phishing protection. Clicking the link will then lead the recipient to whatever malicious website the phisher had in mind. Even if the user just replies with “Y” and then decides not to follow the link—because it looks slightly off—the phishers will know that they have found a likely target for more attacks.

It’s also important to know that there are similar instructions for the Chrome browser:

> “Reply with 1, exit the SMS message, and reopen the SMS activation link, or copy the link to Google Chrome to open it.)”

**How to avoid smishing scams**

*   Never reply to suspicious messages, even if it’s only a “Y” or “1.” It will tell the phishers they have a live number and they will bombard you with more attempts.
*   Never add a number you don’t know to your Contacts as that will disable the iMessage protection as well.
*   Don’t assume any message is the real deal. If you’re being asked to do something, contact the company directly via a known method you trust. If it turns out to be a fake, you should be able to report it to them, there and then.
*   If you live somewhere with a Do Not Call list or spam reporting service, make full use of it. Report bogus messages and numbers.
*   Your mobile device may already have some form of “safe” message ID enabled without you knowing. It’s tricky to give specific advice here because of the sheer difference of options available on models of phone, but the Options / Safety / Security / Privacy menus are a good place to start.
*   Check the link before you click it or copy it in your browser. Is it exactly what you would expect it to be? Scammers often use typosquatting techniques (for example evri\[.\]top instead of the legitimate evri\[.\]com, or they fabricate a link that uses the subdomain to make it look legitimate (for example usps.com-track.infoam\[.\]xyz). If it doesn’t look real then don’t click on it.
*   If a message sounds too good (or bad) to be true, it probably is.

 A week in security (January 6 &#8211; January 12) 

With the advent of virtual reality, everyone got scared that the life we ​​know will disappear, and only…

With the advent of **virtual reality**, everyone got scared that the life we ​​know will disappear, and only those who understand new technologies will be able to find work. Remember what they said about newspapers. And about television. Radio. It seems likely that the same will play out in real life. Just consider what’s already unfolding in virtual reality, within metaverses like Fortnite, Roblox, Holiverse, and Decentraland.

****What does the “reality disappearance” mean?****

The disappearance of reality in the context of the popularity of the **metaverse** does not mean the disappearance of the physical world. It is rather a transformation of our perception and the usage of the real world. Here is how such transformation can happen. 

****Psychological disappearancе****

Let’s start with a simple example. Remember how, as children, we used to play the console for hours, forgetting about lunch? Or look at your children. How many times do you have to say it before they finally sit at the table? Now imagine this feeling, but taken to a new level, where the virtual world feels more interesting and important than the real one.

But haven’t you noticed that we’ve been living this way for the past ten years? Tinder, Facebook, Instagram, and TikTok are gradually consuming several hours of our time every day.

Here’s an example of how a man psychologically disappears in a game. There is a character in World of Warcraft. In virtual reality, this person is a hero, an idol who is looked up to. And what about real life?

There is an ordinary office worker in glasses in a cool unit, whom sometimes even the cleaning lady does not notice. Where would this person be more comfortable? Of course, where he or she is a role model. It’s like choosing what to have for tea: a sweet cake with thick whipping cream or sauerkraut. Well, obviously, in terms of psychology, the man will choose the virtual world in the given situation.

Now imagine that all your communication, work, and even cultural events have shifted to the digital world, the metaverse. Without leaving home, you arrange business meetings, go to concerts, and have fun with friends. It seems like science fiction but it is already a reality.

Travis Scott has collected 12 million viewers in Fortnite. Why go to a real stadium if you can go to a popular rapper’s concert without leaving your home? And without being afraid of a crowd of fans or risking being trampled. Convenient, right?

More and more people understand that there is no point in wasting time in traffic jams if you can solve everything online. And this is just the beginning.

****Economic disappearancе****

Now imagine that money also goes into the virtual world. No, it’s not just about cryptocurrency. People buy virtual land for millions of dollars, sew clothes for avatars, and collect NFTs, like previous stamps or coins.

Here’s an example. Someone bought a Gucci bag in Roblox for $4,000. Although it cost more than in real life, it was still bought. For some, this bag is a way to show status, even in the game.

****Land in Decentraland, avatars in Holiverse and turning tеxt into vidео** **

If you look closely, the “disappearance of reality” has already begun. The only thing is that it’s not as bright as in science fiction movies. We do not connect wires to our heads to get into the virtual world, but, it looks like, we are gradually disappearing there. 

****People buy plots of virtual land for millions of dollars and hope****

For example, in 2021, someone bought a plot of land in Decentraland for $2 million. This is virtual land, you can’t even touch it! Tomorrow the server will burn out, the Internet will be turned off, and no one will remember it. However, for such people, this is not a game, but an investment. They believe that tomorrow virtual real estate will become even more valuable.

The same thing with clothes, which we love to buy in reality. Now imagine that you are buying not a jacket or sneakers, but a skin for your avatar. You do not understand why, but thousands of people around the world do this. In games like Fortnite or Holiverse, this is completely normal because people pursue their own goals there.

For the buyer, this is a matter of status. Because this bag makes his avatar authentic. And that’s cool.

Why is this cool? Here’s an example. A virtual character under the nickname Lil Мiquelа lives only on the Internet. In reality, no one fully understands how she appeared.

Although Miquela does not exist in real life, millions of subscribers follow her on Instagram. She advertises brands, stars in campaigns, and even releases music. Her creators earn millions, and for subscribers, she is “more than real.”

**Holiverse: аvatar as a digital twin**

Just imagine: you take a sample of your DNA at home, and within a couple of days, you receive a digital copy of yourself, an avatar that lives in a virtual world, mimics your behaviour, and adapts to reflect any changes. This avatar does not just copy your body, it knows exactly how your body will react to different physical loads, food products and even cosmetics. This concept is being developed by the **Holiverse** startup, led by Lado Okhotnikov.

The idea looks fresh. Instead of wasting time and money on trying different medicines, you can use your virtual double. For example, you can:

*   find out how your physical condition will change if you add new workouts;
*   try which products will improve your life and which ones you better exclude;
*   test supplements or medicine that you are planning to take.

Lado Okhotnikov and his team emphasize user accessibility. To create a digital copy, you just need to take a DNA test at home, using a test kit that can be purchased at a pharmacy near your home or on a marketplace. Then you will need to send this sample to the lab, and after a short period, you will receive an exact copy of yourself: an avatar that can predict your body’s reactions with incredible accuracy.

The main advantage of Holiverse is the cost of the service. Lado Okhotnikov aims to make this technology available to everyone, turning personalized medicine from luxury into a necessity.

**Luma: turns text into video**

**Luma AI** presented Dream Machine; a service that “brings the text to life.” In terms of quality, the neural network is almost as good as Sora, one of the most powerful generative models. But this startup has a big advantage; Dream Machine is available to everyone. The neural network works on a new architecture and is already bypassing competitors like Runway Gen-2 or Pika. The video is realistic: without jerks, and the characters look natural and are not distorted.

Although the videos are short, a year ago this was considered science fiction. In a year or two, the service may be able to offer something truly significant. For example, tools for generating full-fledged virtual worlds.

Who knows, maybe in a few years we will be able to design entire virtual cities at home in a couple of minutes, simply by describing them in words. Or turn our ideas into animated films available to a million audience in metaverses.

****And what’s next?****

Being scared of technology is the same as trying to stop progress. However, even with the advent of that very virtual reality which everyone is talking about, real life will not go anywhere. You will still go to stores, equipment will still break down, and someone will still come to fix it. The virtual world can captivate, but it will not replace everything. It will not be possible to give up reality quickly and painlessly.

****SUMMARY****

*   **Phishing Scam Targets Job Seekers: Cybercriminals impersonate CrowdStrike recruiters to distribute cryptominer malware via fake job offers.**

*   **Malware Delivery: Victims are tricked into downloading a malicious app from a fake CrowdStrike website, and installing XMRig to mine Monero cryptocurrency.**

*   **Evasion Tactics: The malware limits CPU usage, scans for security tools, and uses startup scripts to remain undetected and persistent.**

*   **Rising Fake Job Scams: Similar tactics are increasingly common, with groups like Lazarus using fake job offers to deploy malware.**

*   **Safety Tips: Verify job offers through official channels, avoid unsolicited software downloads, and use endpoint protection to detect threats.**

Cybercriminals are deploying a tricky new phishing campaign impersonating the cybersecurity firm CrowdStrike‘s recruiters to distribute a cryptominer on unsuspecting job seekers’ devices. This malicious scheme leverages the allure of employment at a reputable cybersecurity firm to trick victims into downloading malware.

According to CrowdStrike’s blog post, the attack was detected on 7 January 2025 and began with a phishing email that appears to be part of CrowdStrike’s recruitment process. The email entices the target with the prospect of a junior developer interview and provides a link to schedule the meeting. Clicking the link directs the victim to a cleverly designed imposter website that mimics CrowdStrike’s branding.

This deceptive website offers downloadable “employee CRM applications” for both Windows and macOS users. Regardless of the chosen platform, downloading the application triggers the installation of a malicious Windows executable written in Rust. This executable acts as a downloader for XMRig, a well-known cryptominer, which starts mining Monero cryptocurrency. This privacy coin is a popular choice for cybercriminals because it is hard to trace.

The screenshot shows the malicious phishing site containing download links for the fake CRM application (Via CrowdStrike)

The executable is designed to evade detection by scanning the system’s processes for malware analysis tools or virtualization software, verifying the presence of at least two CPU cores, and checking for debuggers. If successful, it displays a fake error message to lull the victim into a false sense of security, while downloading additional payloads to establish persistence on the infected device and initiate the XMRig cryptomining process.

However, in this attack, XMRig’s power consumption has been limited to 10% to avoid detection. Moreover, attackers added a batch script in the Start Menu Startup directory to ensure it runs on boot. 

For your information, cryptominers are a type of malware that surreptitiously hijack a computer’s processing power to mine cryptocurrency for the attacker’s benefit. This unauthorized use of resources can cause the device to overheat, potentially leading to hardware damage and a shortened lifespan.

This isn’t a new trend, as fake job scams are becoming more prevalent online, with North Korean group Lazarus persistently using this method to trick unsuspecting users. Hackread recently reported Lazarus group deploying a new macOS trojan called “RustyAttr” since May 2024 to carry out its operations undetected.

Remember, legitimate recruiters rarely request candidates to download software or conduct interviews through unconventional channels. Always verify the authenticity of any job offer before proceeding and rely on official company websites for career opportunities and application processes.

CrowdStrike advises job seekers to be cautious of unsolicited interview offers, including those conducted via instant messaging or group chat, requests for product purchases or payment processing, and software download requirements. 

> _“Organizations can reduce the risk of such attacks by educating employees on phishing tactics, monitoring for suspicious network traffic and employing endpoint protection solutions to detect and block malicious activity.”_

**SUMMARY**

*   **Banshee Stealer targets macOS users, distributed via fake GitHub repositories and phishing sites.**

*   **The malware steals browser credentials, cryptocurrency wallets, 2FA codes, and system details.**

*   **It evades detection using Apple’s XProtect algorithm and deceptive system pop-ups.**

*   **Threat actors expanded targets by removing regional restrictions in the malware.**

*   **Source code leaked in November 2024, but risks remain with evolving cyber threats.**

Cybersecurity researchers at Check Point detected a new version of Banshee Stealer in late September 2024, distributed via phishing websites and fake GitHub repositories. According to their investigation, shared exclusively with Hackread.com this infostealer resembles popular software like Google Chrome, Telegram, and TradingView.

For your information, Banshee macOS Stealer targets macOS users and steals browser credentials, cryptocurrency wallets, and other sensitive data. It was first detected by Elastic Security Labs in August 2024 and was advertised on underground forums like XSS, Exploit, and Telegram, as a “stealer-as-a-service”. 

This newly discovered version includes a string encryption algorithm “stolen” from Apple’s own XProtect antivirus engine, which allowed it to evade detection for over two months. In addition, it doesn’t include its Russian language check, which was previously used to prevent the malware from targeting specific regions, indicating an expansion in its potential targets.

Check Point has identified multiple campaigns distributing the malware through phishing websites, although it’s unclear if they are carried out by previous customers. Threat actors utilized GitHub repositories for Banshee distribution, targeting macOS users with Banshee and Windows users with Lumma Stealer. Malicious repositories were created over three waves, appearing legitimate with stars and reviews, and luring users into downloading malware

Banshee Stealer can harvest data from web browsers, cryptocurrency wallets, and files with specific extensions, including stealing login credentials from web browsers like Chrome, Brave, Edge, and Vivaldi. It also targets browser extensions, specifically those for cryptocurrency wallets, potentially compromising your digital assets.

Additionally, it can capture your Two-Factor Authentication (2FA) credentials, bypassing an extra layer of security for your accounts. Furthermore, it drains off software and hardware details from your device, along with your external IP address and macOS passwords, giving attackers a complete picture of your system.

Also, Banshee Stealer utilizes deceptive pop-ups that mimic legitimate system prompts. These pop-ups can trick you into unknowingly revealing your macOS password, granting the malware administrative access to your system. The malware employs anti-analysis techniques to avoid detection by security tools.

This makes it difficult to identify its presence on your device using traditional methods. Once stolen, your data is sent to the attacker’s command-and-control servers through encrypted and encoded channels, making it challenging to track or intercept. Its source code leaked online in November 2024, leading to its shutdown. Still, it highlights how cyber threats are evolving continually. 

“Businesses must recognize the broader risks posed by modern malware, including costly data breaches that compromise sensitive information and damage reputations, targeted attacks on cryptocurrency wallets that threaten digital assets, and operational disruptions caused by stealthy malware that evades detection and inflicts long-term harm before being identified,” CPR researchers noted in the blog post.

Ms. Ngoc Bui, Cybersecurity Expert at Menlo Security, a Mountain View, Calif.-based provider of browser security commented on the latatest development stating, _“_This new Banshee Stealer variant exposes a critical gap in Mac security. While companies are increasingly adopting Apple ecosystems, the security tools haven’t kept pace. Even leading EDR solutions have limitations on Macs, leaving organizations with significant blind spots. We need a multi-layered approach to security, including more trained hunters on Mac environments._“_

The most recent iteration of the open source infostealer skates by antivirus programs on Macs, using an encryption mechanism stolen from Apple's own antivirus product.

The macOS infostealer "Banshee" has been spotted skating by antivirus programs using a string encryption algorithm it stole from Apple.

Banshee has been spreading since July, primarily via Russian cybercrime marketplaces, where it was sold as a $1,500 "stealer-as-a-service" for Macs. It's designed to steal credentials from browsers — Google Chrome, Brave, Microsoft Edge, Vivaldi, Yandex, and Opera — and browser extensions associated with cryptocurrency wallets — Ledger, Atomic, Wasabi, Guarda, Coinomi, Electrum, and Exodus. Plus, it lifts additional information about targeted systems, including software and hardware specifications, and the password needed to unlock the system.

It was far from a perfect tool, widely detected by antivirus programs, thanks in part to its being packaged entirely in plaintext. But on Sept. 26, researchers from Check Point observed a more potent variant. This more successful variant remained otherwise undetected for months, primarily because it was encrypted with the same algorithm used by Apple's Xprotect antivirus tool for macOS.

**Banshee Malware Steals From XProtect**

XProtect is Apple's decade-and-a-half-old anti-malware engine for macOS. To detect and block malware, it uses "Remediator" binaries, which combine various methods and tools for antivirus-ing, including YARA rules, which contain patterns and signatures associated with known threats.

Check Point found that the same encryption algorithm that protects XProtect's YARA rules also concealed the September variant of Banshee.

It's not clear how the malware author — nom de guerre "0xe1" or "kolosain" — gained access to that algorithm.

"It could be that they performed a reverse engineering of the XProtect binaries, or even read relevant publications, but we can't confirm it," Antonis Terefos, reverse engineer at Check Point Research, speculates. "Once the string encryption of macOS XProtect becomes known — meaning the way the antivirus is storing the YARA rules is reverse-engineered — threat actors can easily 'reimplement' the string encryption for malicious purposes," he says.

Either way, the effect was significant. "The majority of the antivirus solutions in VirusTotal detected the initial Banshee samples using plaintext, but once the developer introduced this novel string encryption algorithm, none of the approximately 65 antivirus engines in VirusTotal detected it," he says.

That remained the case for around two months. Then, on Nov. 23, Banshee's source code was leaked on the Russian language cybercrime forum "XSS." 0xe1 shuttered his malware-as-a-service (MaaS) operation, and antivirus vendors incorporated associated YARA rules in due course. But even after that point, Terefos reports, the encrypted Banshee remained undetected by most engines on VirusTotal.

**How Banshee Stealer Is Spreading in Cyberattacks**

Since late September, Check Point has identified more than 26 campaigns spreading Banshee. Broadly speaking, they can be grouped into two clusters.

In three waves of campaigns lasting from mid-October to early November, threat actors spread the infostealer via GitHub repositories. The repositories promised users cracked versions of popular software, like Adobe programs and various image and video editing tools. The malware was concealed behind generic file names such as "Setup," "Installer," and "Update." This same cluster of activity also targeted Windows users with the popular Lumma Stealer.

The remaining campaigns spread Banshee via phishing sites, of one form or another. In these cases, the attackers disguised the malware as various popular software programs, including Google Chrome, TradingView, Zegent, Parallels, Solara, CryptoNews, MediaKIT, and Telegram. If a visitor was using macOS, they'd get a download link.

More, varying campaigns could be on the way, now that Banshee has been leaked. Thus, Terefos says, "Despite macOS traditionally being regarded as more secure, Banshee’s success demonstrates the importance for macOS users to remain vigilant and aware of the threats."

Banshee 2.0 Malware Steals Apple's Encryption to Hide on Macs

A hack of location data company Gravy Analytics has revealed which apps are—knowingly or not—being used to collect your information behind the scenes.

Some of the world’s most popular apps are likely being co-opted by rogue members of the advertising industry to harvest sensitive location data on a massive scale, with that data ending up with a location data company whose subsidiary has previously sold global location data to US law enforcement.

The thousands of apps, included in hacked files from location data company Gravy Analytics, include everything from games like _Candy Crush_ and dating apps like Tinder to pregnancy tracking and religious prayer apps across both Android and iOS. Because much of the collection is occurring through the advertising ecosystem—not code developed by the app creators themselves—this data collection is likely happening without users’ or even app developers’ knowledge.

“For the first time publicly, we seem to have proof that one of the largest data brokers selling to both commercial and government clients appears to be acquiring their data from the online advertising ‘bid stream,’” rather than code embedded into the apps themselves, Zach Edwards, senior threat analyst at cybersecurity firm Silent Push and who has followed the location data industry closely, tells 404 Media after reviewing some of the data.

The data provides a rare glimpse inside the world of real-time bidding (RTB). Historically, location data firms paid app developers to include bundles of code that collected the location data of their users. Many companies have turned instead to sourcing location information through the advertising ecosystem, where companies bid to place ads inside apps. But a side effect is that data brokers can listen in on that process and harvest the location of peoples’ mobile phones.

“This is a nightmare scenario for privacy, because not only does this data breach contain data scraped from the RTB systems, but there's some company out there acting like a global honey badger, doing whatever it pleases with every piece of data that comes its way,” Edwards says.

Included in the hacked Gravy data are tens of millions of mobile phone coordinates of devices inside the US, Russia, and Europe. Some of those files also reference an app next to each piece of location data. 404 Media extracted the app names and built a list of mentioned apps.

The list includes dating sites Tinder and Grindr; massive games such as _Candy Crush_, _Temple Run_, _Subway Surfers_, and _Harry Potter: Puzzles & Spells_; transit app Moovit; My Period Calendar & Tracker, a period-tracking app with more than 10 million downloads; popular fitness app MyFitnessPal; social network Tumblr; Yahoo’s email client; Microsoft’s 365 office app; and flight tracker Flightradar24. The list also mentions multiple religious-focused apps such as Muslim prayer and Christian Bible apps, various pregnancy trackers, and many VPN apps, which some users may download, ironically, in an attempt to protect their privacy.

The full list can be found here. Multiple security researchers have published other lists of apps included in the data, of varying sizes. Our version is relatively larger because it includes both Android and iOS apps, and we decided to keep duplicate instances of the same app that had slight name variations to make it easier for readers to search for apps they have installed.

Although this dataset came from an apparent hack of Gravy, it is not clear whether Gravy collected this location data itself or sourced it from another company, or which location company ultimately owns it or is licensed to use it.

Much of the location data attached to these app names does not have a time stamp. But there are indications it dates from 2024. One of the apps listed is _Call of Duty: Mobile_, and specifically its Season 5 iteration, which launched in May 2024.

Gravy is a company that powers much of the rest of the location data industry. It collates mobile phone location data from various sources, then sells that to commercial companies or, through its subsidiary Venntel, to US government agencies. Norwegian outlet NRK and I previously revealed the flow of location data from a handful of ordinary apps to Gravy and then to Venntel. Venntel’s clients have included Immigration and Customs Enforcement, Customs and Border Protection, the IRS, the FBI, and the Drug Enforcement Administration.

Venntel has also provided the underlying data for another government-bought surveillance tool called Locate X. 404 Media and a group of other outlets showed last year how that tool, made by a company called Babel Street, could be used to monitor visitors to out-of-state abortion clinics.

But the newly hacked data shows for the first time just how many apps could be part of a location data supply chain, even if their developers are not aware of it. Most app developers and companies included in the list did not respond to a request for comment. Flightradar24 said in an email that it had never heard of Gravy, but that it does display ads, which “help keep Flightradar24 free.”

Tinder said in an email that “Tinder takes safety and security very seriously. We have no relationship with Gravy Analytics and have no evidence that this data was obtained from the Tinder app” but did not answer questions about ads inside the app.

Muslim Pro, one of the Muslim prayer apps included in the list, said in an email that it was not aware of Gravy. “Yes, we display ads through several ad networks to support the free version of the app. However, as mentioned above, we do not authorize these networks to collect location data of our users,” the email said. That does not necessarily mean that a member of the advertising ecosystem can’t extract such data, though. (In 2020 I revealed Muslim Pro was selling its users’ location data to a company called X-Mode, whose clients included US military contractors; Muslim Pro stopped the practice after my reporting.)

A Grindr spokesperson told 404 Media in an email that “Grindr has never worked with or provided data to Gravy Analytics. We do not share data with data aggregators or brokers and have not shared geolocation with ad partners for many years. Transparency is at the core of our privacy program, therefore the third parties and service providers we work with are listed here on our website.” Grindr was previously found to have allowed data brokers to obtain its users’ location data.

It’s important that the data appears to be sourced through real-time bidding, because that dictates who is responsible (rogue members of the advertising industry and the tech giants that facilitate that industry), how users can protect themselves (attempting to block ads), and the fact that massive app publishers may not even be aware their users’ data is being harvested and therefore might not know how to stop it. An app developer will know if it implemented location-data-gathering code itself. It might not know that some company, somewhere, is silently listening in on the advertising process and siphoning data from their app.

Surveillance firms can obtain RTB data by acquiring ad tech companies and posing as prospective advertisers. The spy-run location data company doesn’t need to successfully place an ad; instead, it is able to gather data on devices by simply being plugged into that industry. Location data in this case can also include a users’ IP address, which is then geolocated to give their coarse location.

Last January, 404 Media reported on an Israeli surveillance company called Patternz, which was sourcing masses of location data through the RTB process.

In an exposed training video, Patternz showed some of the popular apps it got location data from: 9GAG, Kik, sports app FUTBIN, caller ID apps such as CallApp and Truecaller; and various word, sudoku, and solitaire puzzle games. Every one of these apps are also in the Gravy data. This suggests that Gravy, or wherever Gravy got that data from, also sourced it from interacting with the advertising system rather than location-tracking code baked into the apps.

404 Media shared some of the location data with another security researcher with knowledge of the advertising and location data industries. “It appears that at least some of this data would likely have been sourced from advertising related, real-time bidding,” Krzysztof Franaszek, founder of Adalytics, a digital forensics firm, told 404 Media after reviewing the data. He pointed out some of the user-agents in the file, which show how a user’s device connected to a service, referenced “afma-sdk.” That is a string used by Google’s Mobile Ads SDK (software development kit). In other words, in some cases, it is Google’s advertising platform that is delivering the ads that are eventually leading to this tracking by outside companies and potentially government contractors.

Google did not respond to multiple requests for comment for this article. Neither did Apple.

Franaszek also says that “a significant amount of this geolocation dataset appears to be inferred by IP address to geolocation lookups, meaning the vendor or their source is deriving the user's geolocation by checking their IP address rather than by using GNSS \[Global Navigation Satellite System\]/GPS data. That would suggest that the data is not being sourced entirely from a location data SDK.”

“What we’re seeing here in this data appears to me to be a huge diversity of apps,” Edwards says. “That’s not what you see from an SDK ingestion; that’s what you see from bulk RTB ingestions.”

In December the Federal Trade Commission banned another location data company called Mobilewalla from collecting consumer data “from online advertising auctions for purposes other than participating in those auctions.” In other words, the agency banned Mobilewalla from participating in the RTB process for building datasets on peoples’ devices. The FTC also said Venntel and Gravy collected data without obtaining user consent, ordered the company to delete historical location data, and banned it from selling data related to sensitive areas like health clinics and places of worship, except in “limited circumstances” involving national security or law enforcement.

404 Media has verified the hacked Gravy data in various ways. Some files include credentials for Gravy’s Snowflake instances, a data warehousing tool. 404 Media checked that the URLs in the hacked files do correspond to real Snowflake instances. One file called “users” contains a long list of companies. Some of these firms denied having any relationship with Gravy; Cuebiq, another location data firm mentioned in the file, told 404 Media it “routinely evaluates available data in the market to determine if they are an appropriate fit for our business. Most do not make it past the evaluation stage to production, as was the case here. Cuebiq tested a limited data sample, which was never made available to our customers, and the data was deleted at the end of the limited trial.”

404 Media also sent a section of the data to another data broker called Datonics. “We investigated the matter described in your email, and the segment IDs in those files are those of Gravy, not Datonics,” the company said in an email.

Unacast, which merged with Gravy in 2023, did not respond to multiple requests for comment, both on the hack and whether it or any of its suppliers have derived location data from the real-time bidding process.

Texas has become a leading enforcer of internet rules. Its latest probe includes some platforms that privacy experts describe as unusual suspects.

Over the past decade, Texas attorney general Ken Paxton has wielded his office’s significant resources to investigate well-known tech giants including Google and Meta over how they moderate content and treat rivals. He helped win settlements against Apple for allegedly misleading users and is suing TikTok for allegedly endangering children's privacy. Now, Paxton’s latest tech investigation includes an expansive number of targets, WIRED has learned.

Rumble, Quora, and WeChat are among the 15 companies from which Texas has demanded answers by next week about their collection and use of data of people under 18 years old. Paxton announced the investigation in a press release last month but named only four of the companies being probed—Character.AI, Red­dit, Insta­gram, and Dis­cord. WIRED obtained the names of additional targeted companies through a public records request. They also include Kick, Kik, Pinterest, Telegram, Twitch, Tumblr, WhatsApp, and Whisper.

Paxton’s office did not respond to requests for comment, including about how it chose which businesses to investigate. But the variety of companies questioned highlights the sprawling reach of a new Texas law aimed at increasing oversight of minors’ use of social media and chat services.

Three experts in youth privacy regulations who have been following Paxton’s enforcement efforts say the new investigation should be treated credibly, and they believe it could result in companies agreeing to improve their practices. The alternative could be up to hundreds of millions of dollars in penalties per company. “When you bring all the statutes together, Texas has a pretty significant hammer,” says Paul Singer, a partner and section chair at the law firm Kelley Drye & Warren.

Spokespeople for Character.AI and Tumblr say they take safety issues seriously. Meta and WeChat declined to comment. Other companies under investigation did not respond to requests for comment.

Paxton launched his probe three days after the families of an 11-year-old girl and 17-year-old boy in Texas sued chatbot startup Character.AI, claiming the company designed its product in an unsafe way that exposed the kids to sexualized and violent responses. In October, a similar case was filed in Florida by the family of a 14-year-old who shot himself to death allegedly following conversations with a Character.AI chatbot. Character.AI later introduced an experience aimed at kids and plans to roll out parental controls.

Other services under investigation including Kik, Instagram, and Discord have faced public scrutiny over their use by children. But less so WeChat, a messaging app popular among Chinese Americans, and Quora, a forum for crowdsourcing information that’s recently expanded into AI chatbots.

Paxton’s interest in Rumble, a YouTube-like website popular among US conservative political commentators, is also perhaps unexpected given his track record of partisan views about social media companies. Rumble has touted itself as a haven for free expression, unlike platforms that engage in allegedly heavier content moderation. Paxton is a Republican and has criticized platforms that unfairly silence Texans.

The privacy experts who spoke with WIRED described Rumble, Quora, and WeChat as unusual suspects but declined to speculate on the rationale behind their inclusion in the investigation. Josh Golin, executive director of the nonprofit Fairplay, which advocates for digital safety for kids, says concerns aren’t always obvious. Few advocacy groups worried about Pinterest, for example, until the case of a British teen who died from self-harm following exposure to sensitive content on the platform, he says.

Paxton’s press release last month called his new investigation “a critical step toward ensuring that social media and AI companies comply with our laws designed to protect children from exploitation and harm.”

The United States Congress has never passed a comprehensive privacy law, and it hasn’t significantly updated child online safety rules in a quarter century. That has left state lawmakers and regulators to play a big role.

Paxton’s investigation centers on compliance with Texas’ Securing Children Online through Parental Empowerment Act, or SCOPE, which went into effect in September. It applies to any website or app with social media or chat functions and that registers users under the age of 18, making it more expansive than the federal law, which covers only services catering to under-13 users.

SCOPE requires services to ask for users’ age and provide parents or guardians power over kids’ account settings and user data. Companies also are barred from selling information gathered about minors without parental permission. In October, Paxton sued TikTok for allegedly violating the law by providing inadequate parental controls and disclosing data without consent. TikTok has denied the allegations.

The investigation announced last month also referenced the Texas Data Privacy and Security Act, or TDPSA, which became effective in July and requires parental consent before processing data about users younger than 13. Paxton’s office has asked the companies being investigated to detail their compliance with both the SCOPE Act and the TDPSA, according to legal demands obtained through the public records request.

In total, companies must answer eight questions by next week, including the number of Texas minors they count as users and have barred for registering an inaccurate birthdate. Lists of whom minors’ data is sold or shared with have to be turned over. Whether any companies have already responded to the demand couldn’t be learned.

Tech company lobbying groups are challenging the constitutionality of SCOPE Act in court. In August, they secured an initial and partial victory when a federal judge in Austin, Texas, ruled that a provision requiring companies to take steps to prevent minors from seeing self-harm and abusive content was too vague.

But even a complete win might not be a salve for tech companies. States including Maryland and New York are expected to enforce similar laws starting later this year, says Ariel Fox Johnson, an attorney and principal of the consultancy Digital Smarts Law & Policy. And state attorneys general could resort to pursuing narrower cases under their tried-and-true laws barring deceptive business practices. “What we see is often information gets shared or sold or disclosed in ways families didn’t expect or understand,” Johnson says. “As more laws are enacted that create firm requirements, it seems to be becoming more clear that not everybody is in compliance.”
