There are some classics on this list — the ever-present “Password” password, Passw0rd (with a zero, not an “O”) and “123456.”

Thursday, May 2, 2024 14:00

Brute force attacks are one of the most elementary cyber threats out there. Technically, anyone with a keyboard and some free time could launch one of them — just try a bunch of different username and password combinations on the website of your choice until you get blocked.  

Nick Biasini and I discussed some of the ways that organizations can defend against brute force attacks since detection usually doesn’t fall into the usual bucket (ex., there’s nothing an anti-virus program could detect running). But a good place to start just seems to be implementing strong password rules, because people, unsurprisingly, are still using some of the most obvious passwords that anyone, attacker or not, would guess. 

Along with our advisory on a recent increase in brute force attacks targeting SSH and VPN services Cisco Talos published a list of IP addresses associated with this activity, along with a list of usernames and passwords adversaries typically try to use to gain access to a network or service. 

There are some classics on this list — the ever-present “Password” password, Passw0rd (with a zero, not an “O”) and “123456.” This tells me that users still haven’t learned their lesson. It’s somewhat funny to think about some well-funded actor just being like, “Well, let me try to ‘hack’ into this machine by using ‘123456’” as if they’re in a parody movie, but if they already can guess a username based off someone’s real name, it’s not that unlikely that password is being used somewhere. 

A few other example passwords stood out to me: “Mart1x21,” because I can’t tell if this is just someone named “Martin” or a play on the month of March, and things like “Spring2024x21” and “April2024x21” because I appreciate the idea that someone using that weak of a password thinks that adding the extra three characters onto “April2024” is really going to throw an attacker off. 

Looking at this list got me thinking about what some potential solutions are to the internet’s password problem, and our ever-present battle to educate users and warn them about the dangers of using weak or default passwords. 

Going passwordless is certainly one option because if there just are no passwords to log in, there’s nothing text-based an attacker could just start guessing. 

The best solution I’ve seen recently is that the U.K. literally made a law requiring hardware and software manufacturers to implement stronger security standards. The Product Security and Telecommunications Infrastructure (PSTI) that went into effect last month contains a range of security protections companies must follow, but they now include mandatory password rules that will force users to change default passwords when registering for new accounts and stop them from using easy-to-guess passwords like “Admin” and “12345.”  

It would be great if users would just stop using these credentials on their own, but if attackers are still thinking that someone out there is using “Password” as their password, they probably are.  

**The one big thing **

For the first time in several quarters, business email compromise (BEC) was the most common threat in Cisco Talos Incident Response (Talos IR) engagements during the first quarter of 2024. BEC made up 46 percent of all engagements in Q1, a significant spike from Q4 2023, according to the latest Talos IR Quarterly Trends Report. Ransomware, which was the top-observed threat in the last quarter of 2023, decreased by 11 percent. Talos IR also observed a variety of threats in engagements, including data theft extortion, brute-force activity targeting VPNs, and the previously seen commodity loader Gootloader. 

**Why do I care? **

BEC is a tactic adversaries use to disguise themselves as legitimate members of a business and send phishing emails to other employees or third parties, often pointing to a malicious payload or engineering a scheme to steal money. The use of email-hiding inbox rules was the top-observed defense evasion technique, accounting for 21 percent of engagements this quarter, which was likely due to an increase in BEC and phishing within engagements. These are all valuable insights from the field provided in Talos IR’s full report. 

**So now what? **

There are some known indicators of compromise that customers can look for if they suspect The lack of MFA remains one of the biggest impediments for enterprise security. All organizations should implement some form of MFA, such as Cisco Duo. The implementation of MFA and a single sign-on system can ensure only trusted parties are accessing corporate email accounts, to prevent the spread of BEC.

**Top security headlines of the week **

**The chief executive of UnitedHealth Group testified to U.S. Congress on Wednesday regarding the recent cyber attack against Change Healthcare.** Change’s operations went nearly completely dark for weeks earlier this year after a data breach, which likely resulted in millions of patients’ records and personal information being accessed. Lawmakers questioned whether UnitedHealth was too involved in the nation’s medical systems, as Change manages a third of all American patient records and processes more than 15 billion transactions a year at doctor’s offices, hospitals and other medical providers. As a result of the outage, some healthcare practitioners went more than a month without being paid, and many had to tap into their personal funds to keep offices open. UnitedHealth’s CEO told Congress the company was still working to figure out the full extent of the campaign and was talking to U.S. agencies about how to best notify individuals who were affected. The hearing has also generated a conversation around consolidation in the American healthcare industry and whether some groups are controlling too much of the patient base. (The New York Times, CNBC) 

**Vulnerabilities in a popular phone tracking app could allow anyone to view all users’ locations.** A security researcher recently found that iSharing, which allows users to see the exact location of a device, contains a vulnerability that prevented the app's servers from conducting proper checks of user data access. iSharing is advertised as an app for users who want to track friends' and family members’ locations or as an extra layer of security if their device were to be lost or stolen. The flaws also exposed users’ names, profile pictures, email addresses and phone numbers. The researcher who discovered the vulnerability was able to show a proof-of-concept exploitation almost immediately after creating a brand new account on the app. Representatives from the developers of iSharing told TechCrunch that the company’s logs did not show any signs of the vulnerability being exploited prior to the researcher’s disclosure. These types of apps can also be used as “stalkerware,” in which someone who knows a targeted user quietly downloads the app on a target’s phone, and then uses it to remotely track their location. (TechCrunch) 

**Adversaries are hiding malware in GitHub comments, disguising malicious code as URLs associated with Microsoft repositories, and making the files appear trustworthy.** Although some security researchers view this as a vulnerability, Microsoft maintains that it is merely a feature of using GitHub. While adversaries have so far mainly abused this feature to mirror Microsoft URLs, it could theoretically be used to create convincing lures on any GitHub repository. When a user leaves a comment in GitHub, they can attach a file, which is then uploaded to GitHub’s CDN and associated with the related project using a unique URL. GitHub automatically generates the link to download that attachment after adding the file to an unsaved comment, allowing threat actors to attach malware to any repository without the administrators knowing. This method has already been abused to distribute the Readline information-stealing trojan by attaching comments to Microsoft’s GitHub-hosted repositories for “vcpkg” and “STL.” The malicious URL will even still work if the poster deletes the comment, allowing them to reuse the GitHub-generated URL.

PRESS RELEASE

SAN FRANCISCO, April 30, 2024 /PRNewswire-PRWeb/ -- Cobalt, the pioneers of Pentest as a Service (PtaaS) and leading provider of offensive security solutions, today announced its sixth annual State of Pentesting Report. In addition to a deep dive into pentesting trends, this year's report uncovers an industry deeply grappling with how to both use and protect from AI amidst significant resource and staffing constraints.

Pentesting plays a key role in addressing this challenge, equipping organizations with the ability to more frequently security test critical assets, expanded environments, and proliferating cloud applications. As part of the report, Cobalt analyzed 4,068 pentests, revealing a 21% increase in the number of findings per pentest engagement year-over-year (from Cobalt State of Pentesting Report 2022), aligning with increases in Common Vulnerabilities and Exposures (CVE) records. Additionally, findings indicated that the median time to fix vulnerabilities also increased in comparison to previous years.

In addition to its pentesting analysis, the report also includes a survey of more than 900 cybersecurity professionals across the U.S. and U.K. The study digs into how cyber professionals are balancing internal staffing and working with external partners, the push-pull of AI as both a tool and a threat, and the challenges the C-suite faces to lead change. Some of the most critical findings include:

*   Challenges In the Eye of the AI Storm: The study highlights the push-pull relationships cyber security teams have with AI. A huge majority (86%) cite their teams have adopted AI-powered tools on their teams, while on the flip side, seven in ten respondents also cite an increase in threats coming from AI. This aligns with the growth Cobalt experienced in its business. Throughout 2023, Cobalt performed an increasing number of pentests on AI systems, primarily on software products incorporating AI-enabled chatbots to improve user experience. The most common vulnerabilities uncovered included prompt injection (including jailbreak), model denial of service, and prompt leaking (sensitive information disclosure). Despite the increased investment, many teams (59%) worry they are still trailing behind the AI threat.
    
*   Short Staffing Shifts From Concerning to Significant Risk: The report captures the reality of significant industry layoffs and uncertainty that plagued 2023 and the hangover effect layoffs continue to have on threat levels. Thirty-one percent of respondents said their organization conducted layoffs during the past six months, and ⅓ of those agree their organization faces greater cyber risk due to those departures. Most concerning is that there are no signs of a strong staffing recovery. Nearly one-third of respondents report being on a hiring freeze, and 29% expect to do more layoffs still this year. Looking at the data, Cobalt sees an increase in the overall volume of high and critical severity findings of 39% year over year. This is leading many companies to look at how they will utilize partnerships and vendors to improve security measures, with 59% agreeing they will increase pentesting in 2024.
    
*   C-Suite Pressures: As attacks rise, C-suite executives are increasingly finding themselves at the top of the accountability and liability food chains. It's clear that respondents are feeling this pressure; C-suite is 31% more likely than non-C-suite to say the industry environment is impacting their mental health, and 51% more likely to say it's impacting their physical health. Like their staff, they cite challenges balancing talent shortages and budget constraints against both increasing and emerging threats. Among all groups surveyed, they are the most concerned about AI adoption (33% more than non-C-suite respondents). Despite these challenges, C-suite leadership is proven to be critical to cyber security, with 23% noting that C-suite leadership is more critical than budget to preventing attacks.
    

"With cybersecurity teams strained by staffing shortages and concerns rising about AI's potential to enhance cyberattacks, the importance of pentesting as a proactive measure is key," said Caroline Wong, Chief Strategy Officer at Cobalt. "Our data reinforces the actions we as an industry need to take: prioritizing talent acquisition, exercising caution in AI integration to safeguard against evolving threats, and leveraging pentesting."

"Enterprises today not only face digital threats but the personal toll that these challenges take on their executives," said Chris Manton-Jones, CEO at Cobalt." As leaders, it is crucial to understand that cybersecurity is not just about securing our digital assets but also about ensuring the safety of our entire organization, including ourselves. This is where Cobalt can help make a difference. We close the gaps with security expertise and provide scalable offensive security testing across the entire attack surface. It adds a community of trusted security experts to your team and takes your security program to the next level."

Cobalt's 2024 State of Pentesting Report Reveals Cybersecurity Industry Needs

Unmanaged and unknown Web services endpoints are just some of the challenges organizations must address to improve API security.

Source: Wright Studio via Shutterstock

Organizations shoring up their API security need to pay particular attention to unmanaged or shadow application programming interfaces.

Shadow APIs are Web services endpoints that are no longer in use, outdated, or undocumented, and therefore not actively managed. Application and security teams need to find such APIs and ensure each one is either documented or decommissioned to mitigate the significant risk they present, says Rupesh Chokshi, senior vice president, application security at Akamai.

**The Risk From Unmanaged APIs**

Chokshi is scheduled to present a talk on the topic at the upcoming RSA Conference 2024 in San Francisco next week. In a presentation titled "The Secret Life of APIs: Latest Attack Data Shows What Your APIs are Doing," Chokshi identifies shadow APIs as one of several postural — or implementation-related — issues that organizations must prioritize when tackling API security.

One of the biggest surprises for enterprises that increase their visibility into API activity is the sheer number of shadow endpoints in their environment that they were previously unaware of, Chokshi says. The first step to enabling better API security is to discover these shadow endpoint and either eliminate them or incorporate them into the API security program, he notes.

API security has become an increasingly pressing challenge for IT and security leaders. In recent years, many organizations have deployed APIs extensively to integrate disparate systems, applications, and services in a bid to streamline business processes and boost operational efficiencies. APIs have also played a central role in enabling digital transformation initiatives by giving companies a way to modernize legacy applications, adopt cloud services, and engage more efficiently with customers, partners, and other third parties.

**The API Proliferation Challenge**

The resulting proliferation of APIs has significantly expanded the attack surface at many organizations and exposed them to greater risks, Chokshi says. He points to research from Akamai earlier this year that found that 29% of all Web attacks in 2023 targeted APIs. Common attack vectors included SQL injection, cross-site scripting, session hijacking/session manipulation, and data harvesting attacks. Attackers targeted organizations in certain sectors more frequently than others. More than 44% of all Web attacks in the e-commerce sector, for instance, targeted APIs. Similarly, nearly 32% and 19% of the Web application attacks that business services organizations and healthcare organizations, respectively, encountered last year targeted application programming interfaces.

Chokshi says the API security challenges that most organizations encounter fall under two broad categories: postural and runtime related. Postural issues result from implementation weaknesses, such as those related to shadow APIs. An October 2022 research report from Cequence Security identified more than 31% of all malicious requests — or some 5 billion of 16.7 billion — targeted unknown and unmanaged APIs.

Other common postural problems include unauthenticated resource access, sensitive data in the URL, overly permissive cross-origin resource sharing, and excessive client errors, which can include issues like improper authentication.

The most common runtime problems — or active threats — that organizations typically encounter include unauthenticated attempts to access sensitive API resources; API activity with unusual JSON payloads, like unexpected data types; unexpected or malformed data as part of API requests; and data scraping attempts.

Given the rapidly evolving nature of the API threat landscape, organizations need to ensure they have proper visibility over their API environment, Chokshi notes. In addition to detecting and decommissioning shadow APIs, organizations need to maintain an inventory of their APIs. They also need to harden their API posture by, for instance, correcting flaws in API code and addressing misconfiguration issues; bolstering threat detection and response capabilities; and establishing an API threat hunting capability.

Shadow APIs: An Overlooked Cyber-Risk for Orgs

The newly discovered malware, which has so far mainly targeted Turkish telcos and has links to HiatusRat, infects routers and performs DNS and HTTP hijacking attacks on connections to private IP addresses.

Source: David Fleetham via Alamy Stock Photo

A never-before-seen malware strain is targeting enterprise-grade and SOHO routers to steal authentication details and other data from behind the network edge. It also performs DNS and HTTP hijacking attacks on connections to private IP addresses.

The packet-sniffing malware — dubbed "Cuttlefish" by the Black Lotus Labs team at Lumen Technologies who discovered it —features a zero-click approach to capturing data from users and devices, according to a blog post published May 1.

"Any data sent across network equipment infiltrated by this malware is potentially exposed," according to Black Lotus Labs. Attackers designed the modular malware to be triggered by a specific rule set, in particular to acquire authentication data, with an emphasis on public cloud-based services, the researchers said.

"To exfiltrate data, the threat actor first creates either a proxy or VPN tunnel back through a compromised router, then uses stolen credentials to access targeted resources," according to the post. "By sending the request through the router, we suspect the actor can evade anomalous sign-in based analytics by using the stolen authentication credentials."

Cuttlefish also has a secondary function that gives it the capacity to perform both DNS and HTTP hijacking for connections to private IP space that's associated with communications on an internal network. It can also interact with other devices on the LAN and move material or introduce new agents.

**Cuttlefish's Unique Malware Behavior**

Cuttlefish's capability to eavesdrop on edge networking equipment and perform DNS and HTTP hijacking "has seldom been observed;" however, campaigns such as ZuoRat, VPNFilter, Attor, and Plead exhibited similar behavior, according to Black Lotus Labs.

Unique to Cuttlefish, however, is its capability to zero in on private IP address connections for potential hijack, which is the first time the researchers have observed this capability and is likely for the purposes of anti-detection and persistence, they noted.

"We suspect that targeting these cloud services allows the attackers to gain access to many of the same materials hosted internally, without having to contend with security controls like EDR \[extended detection and response\] or network segmentation," according to the blog post.

The malware's combination of targeting networking equipment that's frequently unmonitored, as well as gaining access to cloud environments that often lack logging is intended to grant long-term persistent access to targeted ecosystems, the researchers noted.

**Turkish Telcos & Links to HiatusRAT**

Cuttlefish has been active since at least last July, with its latest campaign running from October through last month. The bulk of the infections occurred within Turkey via two telecommunications providers (a segment that's frequently targeted by cyberespionage malware), accounting for about 93% of infections, or 600 unique IP addresses.

There also have been "a handful" of non-Turkish victims, including IP addresses of clients likely associated with global satellite phone providers, and potentially a US-based data center, according to Black Lotus Labs.   

Researchers found links — specifically, code similarities and embedded build paths — to HiatusRat, thus they believe Cuttlefish also is aligned with the interests of China-based threat actors. However, so far Black Lotus Labs has not found shared victimology, surmising that the two malware clusters are operating concurrently.

**Infection Process and Execution**

While the researchers have not determined the initial infection vector, they did track the path of Cuttlefish once the targeted device was exploited, they said. The threat actor first deploys a bash script that gathers certain host-based data to send to the command-and-control server (C2). It also downloads and executes Cuttlefish in the form of a malicious binary compiled for all major architectures used by SOHO operating systems.

"This agent implements a multi-step process that begins with installing a packet filter for the inspection of all outbound connections and use of specific ports, protocols, and destination IP addresses," according to the post. "Cuttlefish constantly monitors all traffic through the device and only engages when it sees a particular set of activities."

The C2 sends updated and specified rules of engagement through a configuration file after it receives the host-based enumeration from the initial entry. The rule set directs the malware to hijack traffic destined to a private IP address; if heading to a public IP, it will initiate a sniffer function to steal credentials if certain parameters are met.

**Defending Against Router Attacks**

Aside from including a list of indicators of compromise (IoCs) in its post, the researchers also had separate advice for both corporate network defenders and those with SOHO routers to avoid and detect compromise by Cuttlefish.

Enterprise organizations should look for attacks on weak credentials and suspicious login attempts, even when they originate from residential IP addresses which bypass geofencing and ASN-based blocking. They also should encrypt network traffic with TLS/SSL to prevent sniffing when retrieving or sending data located remotely, such as when using cloud-based services or performing any type of authentication, the researchers advised.

Organizations that manage these types of routers should ensure that devices do not rely upon common default passwords, as well as that the management interfaces are properly secured and not accessible via the Internet. Inspection of SOHO devices for abnormal files such as binaries located in the /tmp directory or rogue iptables entries, as well as routinely power-cycling these devices to help remove malware samples in-memory can also help organizations avoid compromise. Enterprises also should implement certificate pinning when remotely connecting to high-value assets, such as cloud assets, to prevent threat actors from being able to hijack connections.

Consumers with SOHO routers should follow best practices of regularly rebooting routers and installing security updates and patches, as well as retiring and replacing routers that reach their end of life and thus support from their respective vendors.

'Cuttlefish' Zero-Click Malware Steals Private Cloud Data

Talos also recently helped to responsibly disclose and patch other vulnerabilities in the Foxit PDF Reader and two open-source libraries that support the processing and handling of DICOM files.

Wednesday, May 1, 2024 12:00

Cisco Talos’ Vulnerability Research team has disclosed more than a dozen vulnerabilities over the past three weeks, five in a device that allows employees to check in and out of their shifts, and another that exists in an open-source library used in medical device imaging files. 

The Peplink Smart Reader contains several vulnerabilities, including one issue that could allow an adversary to obtain the administrator’s login credentials and the MD5-hashed version of their password. 

Talos also recently helped to responsibly disclose and patch other vulnerabilities in the Foxit PDF Reader and two open-source libraries that support the processing and handling of DICOM files. 

For Snort coverage that can detect the exploitation of these vulnerabilities, download the latest rule sets from Snort.org, and our latest Vulnerability Advisories are always posted on Talos Intelligence’s website.  

**Code execution, information disclosure vulnerabilities in Peplink Smart Reader **

_Discovered by Matt Wiseman._ 

The Peplink Smart Reader is an internet-connected device associated with the PepXIM Time-Logging and Security System. Companies’ employees use this device to check in and out of their shifts, allowing administrators to keep track of time cards and pay. It also can control access to certain buildings, and even public transportation. 

There are two information disclosure vulnerabilities, TALOS-2023-1863 (CVE-2023-43491) and TALOS-2023-1865 (CVE-2023-45209), that are triggered if an adversary sends a specially crafted HTTP message to the targeted device.  

If successful, the attacker could eventually view the active administrator’s username and MD5-hased password. And in the case of TALOS-2023-1865, it goes a step further, potentially allowing the adversary to view wireless network credentials, network configuration details and SNMP configuration details. 

With those credentials (or admin credentials obtained by other means), an adversary could exploit TALOS-2023-1868 (CVE-2023-40146), a privilege escalation vulnerability in the Smart Reader. An adversary could execute a specially crafted command line argument to cause a limited-shell escape and execute unblocked, default busybox functionality to eventually gain access to an uninhibited root shell. 

TALOS-2023-1866 (CVE-2023-45744) is also triggered by a specially crafted HTTP request, but in this case, could allow an adversary to manipulate certain configuration settings on the device. 

The most serious of the issues Talos discovered in the Smart Reader is TALOS-2023-1867 (CVE-2023-39367), a command injection vulnerability that could allow an attacker to execute arbitrary commands. This vulnerability has a 9.1 CVSS score out of 10. An authenticated attacker can leverage this vulnerability to execute arbitrary commands on the device with root privileges and elevate their access to the vulnerable system. 

**Silicon Labs Gecko Platform invalid pointer dereference vulnerability **

_Discovered by Kelly Patterson._ 

An invalid pointer dereference vulnerability exists in the HTTP server header parsing functionality of the Silicon Labs Gecko Platform.  

The Gecko Platform SDK is the collection of Silicon Labs’ wireless software development kits and Gecko Platform into an integrated package. It allows users to develop applications inside Silicon Labs’ internet-of-things software ecosystem. 

TALOS-2024-1945 (CVE-2023-51391) is triggered if an adversary sends the target a specially crafted network packet, which could lead to a denial-of-service condition. 

_Discovered by Emmanuel Tacheau._ 

There is an incorrect type conversion vulnerability in OFFIS DCMTK, an open-source library often used to manage, store and convert DICOM files. DICOM is the commonly used file type to transfer, send and store medical imaging files, such as X-rays and ultrasounds.  

Hospitals and companies use DCMTK for various purposes, ranging from product testing to being a building block for research projects, prototypes and commercial products. 

TALOS-2024-1957 (CVE-2024-28130) could allow an adversary to execute arbitrary code on the targeted machine if they trick the user into opening a specially crafted file.  

_Discovered by Emmanuel Tacheau._ 

Another open-source library for handling DICOM files, Grassroots DiCoM, contains three out-of-bounds writer vulnerabilities.  

TALOS-2024-1944 (CVE-2024-25569) and TALOS-2024-1935 (CVE-2024-22373) can be triggered if an adversary tricks the target into opening a specially crafted, malicious DICOM file, eventually allowing them to read out-of-bounds memory. 

TALOS-2024-1924 (CVE-2024-22391) works in the same way, but in this case, causes a heap-based buffer overflow, leading to memory corruption.  

**Three vulnerabilities in Foxit PDF Reader could lead to arbitrary code execution **

_Discovered by KPC._ 

Three vulnerabilities exist in Foxit PDF Reader that could allow an adversary to execute arbitrary code on the targeted machine. 

Foxit PDF Reader is one of the most popular pieces of PDF-reading software currently available and aims to have feature parity with Adobe Acrobat Reader. It also includes a browser plugin to allow users to open files in their web browsers.  

TALOS-2024-1959 (CVE-2024-25648) and TALOS-2024-1958 (CVE-2024-25938) are use-after-free vulnerabilities that can be triggered if an attacker tricks a user into opening a malicious, specially crafted PDF. This could also work if the user has the browser plugin enabled and the adversary tricks them into opening an attacker-controlled webpage. These vulnerabilities could lead to a use-after-free issue, potentially leading to memory corruption and arbitrary code execution. 

There is also a type confusion vulnerability, TALOS-2024-1963 (CVE-2024-25575), that could also lead to memory corruption and arbitrary code execution.

Vulnerabilities in employee management system could lead to remote code execution, login credential theft

China's brain-computer interface technology is catching up to the US. But it envisions a very different use case: cognitive enhancement.

At a tech forum in Beijing last week, a Chinese company unveiled a “homegrown” brain-computer interface that allowed a monkey to seemingly control a robotic arm just by thinking about it.

In a video shown at the event, a monkey with its hands restrained uses the interface to move a robotic arm and grasp a strawberry. The system, developed by NeuCyber NeuroTech and the Chinese Institute for Brain Research, involves soft electrode filaments implanted in the brain, according to state-run news media outlet Xinhua.

Researchers in the US have tested similar systems in paralyzed people to allow them to control robotic arms, but the demonstration underscores China’s progress in developing its own brain-computer interface technology and vying with the West.

Brain-computer interfaces, or BCIs, collect and analyze brain signals, often to allow direct control of an external device, such as a robotic arm, keyboard, or smartphone. In the US, a cadre of startups, including Elon Musk’s Neuralink, are aiming to commercialize the technology.

William Hannas, lead analyst at Georgetown University’s Center for Security and Emerging Technology (CSET), says China is quickly catching up with the US in terms of its BCI technology. “They’re strongly motivated,” he says of the Asian superpower. “They're doing state-of-the-art work, or at least as advanced as anybody else in the world.”

He says China has typically lagged behind the US in invasive BCIs—that is, those that are implanted in the brain or on its surface—choosing instead to focus on noninvasive technology that’s worn on the head. But it’s quickly catching up on implantable interfaces, which are being explored for medical applications.

More concerning, though, is China’s interest in noninvasive BCIs for the general population. Hannas coauthored a report released in March that examines Chinese research on BCIs for nonmedical purposes.

“China is not the least bit shy about this,” he says, referring to ethical guidelines released by the Communist Party in February 2024 that include cognitive enhancement of healthy people as a goal of Chinese BCI research. A translation of the guidelines by CSET says, “Nonmedical purposes such as attention modulation, sleep regulation, memory regulation, and exoskeletons for augmentative BCI technologies should be explored and developed to a certain extent, provided there is strict regulation and clear benefit.”

The translated Chinese guidelines go on to say that BCI technology should avoid replacing or weakening human decisionmaking capabilities “before it is proven to surpass human levels and gains societal consensus, and avoid research that significantly interferes with or blurs human autonomy and self-awareness.”

These nonmedical applications refer to wearable BCIs that rely on electrodes placed on the scalp, also known as electroencephalography or EEG devices. Electrical signals from the scalp are much harder to interpret than those inside the brain, however, and there’s a huge effort in China to use machine learning techniques to improve analysis of brain signals, according to the CSET report.

A handful of US companies are also developing wearable BCIs that arguably fall under the category of cognitive enhancement. For instance, Emotiv of San Francisco and Neurable in Boston are starting to sell EEG headsets intended to improve attention and focus.

The Federal Communications Commission (FCC) has fined the top US wireless carriers a collective $200 million for sharing access to customers' location information without consent, the culmination of an action proposed four years ago as authorities continue to grapple with how to reel in companies' handling of sensitive personal data. For carriers, who note that the fines are based on outdated programs that no longer exist, the action represents unsettled regulatory waters as requirements for handling customer data security and privacy in the modern era continue to shake out.

Specifically, the FCC fined Sprint and T-Mobile USA, which have merged since the investigation began, more than $12 million and $80 million, respectively; AT&T more than $57 million; and Verizon almost $47 million.

The agency proposed the fines in 2020 based on an investigation that started after reports that a Missouri sheriff consistently used a "location-finding service" operated by Securus, a company that provides and monitors telecommunications service in correctional facilities, to access the location information of the wireless carriers' customers without their consent between 2014 and 2017.

The case ultimately revealed that the four telecom providers had programs in place at the time that were selling customer-location data to two data-aggregation firms, who then resold access to this data to other entities.

"This action demonstrated the carriers offloading obligations to obtain customer consent onto downstream recipients of location information," which in many instances meant customers did not actually consent to releasing their data, according to an FCC press release (PDF) on the decision. For their part, the carriers say that the data was shared with the third parties in order to enable location-based safety services such as roadside assistance.

"Our communications providers have access to some of the most sensitive information about us," said FCC Chairwoman Jessica Rosenworcel in a statement on the fines. "These carriers failed to protect the information entrusted to them."

This is likely not the end of the fines: The commission also said that it plans to continue to resolve these types of older privacy cases regarding customer data, holding "all carriers accountable and making sure they fulfill their obligations to their customers as stewards of this most private data," she said.

**Wireless Cos Push Back on FCC Privacy Fines**

All of the carriers confirmed to Dark Reading that they will go to court to appeal the decision, which was based on a provision of the Communications Act of 1934 that requires US wireless carriers to take reasonable steps to safeguard specific customer data, such as location information.

Generally, the companies claim the action by the FCC is based on outdated scenarios at the telecom providers that have since been remedied, and they no longer allow third parties to access sensitive customer location-based data.

Verizon spokesman Rich Young says the order concerns an old program at Verizon that required customers to opt in and was shut down more than five years ago. The program "was intended to support services like roadside assistance and medical alerts," he tells Dark Reading, and Verizon shuttered it when the company discovered it was being used fraudulently.

"Verizon is deeply committed to protecting customer privacy," Young says. "Unfortunately, the  FCC's order gets it wrong on both the facts and the law, and we plan to appeal this decision."

For its part, T-Mobile USA gave Dark Reading a statement to much the same effect: "This industry-wide third-party aggregator location-based services program was discontinued more than five years ago after we took steps to ensure that critical services like roadside assistance, fraud protection, and emergency response would not be disrupted. We take our responsibility to keep customer data secure very seriously and have always supported the FCC's commitment to protecting consumers, but this decision is wrong, and the fine is excessive. We intend to challenge it."

AT&T too plans to appeal the fines, which apply for a service that was discontinued in 2019.

"The FCC order lacks both legal and factual merit," a spokesperson says. "It unfairly holds us responsible for another company's violation of our contractual requirements to obtain consent, ignores the immediate steps we took to address that company's failures, and perversely punishes us for supporting life-saving location services like emergency medical alerts and roadside assistance that the FCC itself previously encouraged. We expect to appeal the order after conducting a legal review."

A spokesman for CTIA, a telecommunications industry trade association representing US carriers and resellers, also criticized the fines, citing a "broken enforcement process" on the part of the FCC that deserves examination by Congress.

"After touting the potential of location-based services to provide benefits like roadside assistance and emergency medical alerts, the FCC refused CTIA's request for guidance on how providers should run those programs, and is now penalizing providers for facilitating them," said CTIA senior vice president and chief communications officer Nick Ludlum, in a media statement.

**Carrier Uncertainly: Customer-Privacy Worries Persist**

Complaints that the FCC is behind the times may indeed be justified, as the commission is not known for moving quickly on clarifying how telecom and VoIP providers handle customer privacy.

For instance, it took the FCC 16 years to update how telecom and VoIP providers report data-breaches, issuing new rules in February of this year that they must notify customers whenever there's personally identifiable information (PII) involved in a cyber incident. The new rules — which also require carriers and service providers to report breaches to the FCC, the FBI, and the Secret Service within seven days of discovery — were the first since 2007 to be issued by the commission regarding data-breach notifications.

Meanwhile, the issue of customer privacy when it comes to carriers continues to be a worry, and the fines appear to demonstrate a heavy hand by the FCC in holding communications providers accountable when private customer data leaks. Abroad, other privacy troubles concerning how carriers handle customer data also are brewing.

For example, a huge swathe of telecom customers in Namibia recently were faced with losing their phone service if they didn't hand over sensitive biometric data to the country's premier telco, Mobile Telecommunications Ltd. The potential privacy threat occurred after a well-intentioned plan to combat mobile fraud and identity theft went astray.

Cisco Talos at RSAC 2024

Nutland says he goes into every engagement or new project with a completely open mind and a blank slate — using his background investigating terror operations to find out as much as he can about a particular adversary’s operation.

Monday, April 29, 2024 08:00

If state-sponsored actors are after one thing, it’s to spread fear and uncertainty across the internet. 

There’s always money to be made targeting individual businesses and organizations, but for James Nutland’s work, it’s always about the bigger picture. And his background in studying counterterrorism and interpersonal social dynamics provides him a unique perspective on APTs’ goals and methods. 

Nutland, an analyst with Cisco Talos’ Threat Intelligence and Interdiction team, didn’t begin his journey into cybersecurity through the traditional pathways. Instead, he went to college to obtain his bachelor’s degree in social psychology, particularly interested in social engineering, eventually obtaining his master’s in counterterrorism from the University of East London. 

That may sound like a degree someone gets to serve on a physical battlefield, but as Nutland puts it, security research and counterterrorism carry some of the same throughlines. 

“It’s providing you a set of skills you can then use in multiple modalities,” he said. “It’s the analysis, the eagerness to delve into the unknown, to assess swathes of noisy information, picking out the pieces to establish different threads to try and establish patterns and hopefully attribution — it’s that kind of analytical investigative thinking that really helps for threat hunting.” 

Nutland (right) speaking at MITRE ATT&CK Con last year.

Nutland’s technical experience comes from his undergraduate days when he started working in tech support for his college. Eventually, he got into system administration work after he moved to the U.S. during the peak of the COVID-19 pandemic.  

After various roles protecting both business and academic environments, Nutland decided to apply to Talos essentially on a whim after seeing a job listing whilst researching IOCs on the Talos intelligence center. In his current role, he conducts regular threat hunting and analysis campaigns to learn more about broader trends in the security landscape and state-sponsored threat actors. His work recently led to the disclosure of a campaign targeting Mexico users with tax-themed lure documents called “TimbreStealer,” and he participates in Cisco Talos Incident Response’s Intel-on-Demand service.  

Nutland says he goes into every engagement or new project with a completely open mind and a blank slate — using his background investigating terror operations to find out as much as he can about a particular adversary’s operation.  

“With my academic background, I’m very inquisitive. That’s proven to be a good asset,” he said. “I have a good understanding of the content and presentation of intelligence sought after in security management and operations. It’s great providing this intelligence, but providing actionable intelligence for security teams, understanding what’s required for that, it’s integral for many of the products we produce.” 

Recently, Nutland says he’s been focusing more on tracking prominent and burgeoning ransomware threat actors, as well as researching dark web activities where threat actors are leveraging obfuscated channels for their communication. Social media sites have gotten better about blocking this type of activity, he said, which has pushed them to decentralized communication platforms. He’s also tracking dark web sites that are used for obtaining ransom payments, spreading propaganda and trying to radicalize other users. 

Nutland’s work has also been crucial in Talos’ support of Ukraine during Russia’s invasion. He worked on several victim notifications for the Ukraine Task Force and discovered the malicious use of a defense evasion tool, which can wipe traces and logs of any USB devices that may have been connected to hardware and certain user activity on the host.  

“I initially saw a suspicious specific set of commands that were being run related to the executable, that I was able to track across multiple potential Ukrainian victims which Ukrainian organizations are now looking to crack down on,” Nutland said. 

In all his roles so far in his career, Nutland said he’s experienced various forms of imposter syndrome throughout his career, as many do. He said he often found himself questioning decisions, or feeling like other teammates were more qualified for his role. But at Talos, his managers have encouraged him to turn over every rock and go into every situation, curious and open. That’s allowed him to overcome that imposter syndrome and become a sponge, learning everything he could about a particular topic and becoming an expert in his own right. 

This culminated in a presentation to more than 300 people at the MITRE ATT&CKcon 4.0 in October, where he and his teammate, Nicole Hoffman, gave a talk about how threat actors can use the ATT&CK framework to track adversary activity. 

“Here are these titans of threat intelligence at a world-renowned convention. And here’s me, recently employed at Talos, and with incredible imposter syndrome,” Nutland said. “But there were about 300 people in the room, and Nicole and I knocked it out of the park. I never thought I’d be doing that.” 

Outside of the office, Nutland enjoys playing rugby, and he even was recently able to play a scrimmage against the Colombian National Team, a particular highlight for his career outside of cybersecurity.
