Red Hat Security Advisory 2024-10275-03

LifeLabs managed to hold up a report about a ransomware incident in court for four years. It's now been published.

In 2019, a ransomware attack hit LifeLabs, a Canadian medical testing company. The ransomware encrypted the lab results of 15 million Canadians, and personally identifiable information (PII) of 8.6 million people was stolen.

After noticing the attack, LifeLabs informed its customers and the Canadian privacy regulators, which immediately announced an investigation.

The privacy commissioners of both British Columbia and Ontario finished writing a report about the incident in 2020 but LifeLabs managed to hold that up in court for four years. Now the report is publicly available and some of the findings are both shocking and unsurprising.

According to the report, LifeLabs had several shortcomings before the breach:

*   LifeLabs failed to take reasonable steps to protect personal information and personal health information in its custody and control from theft, loss, and unauthorized access, collection, use, disclosure, copying, modification or disposal.
*   LifeLabs failed to have in place and follow policies and information practices that comply with PIPA and PHIPA
*   LifeLabs collected more personal information and personal health information than is reasonably necessary to meet the purpose for which it was collected.

Additionally, the investigation found that LifeLabs didn’t comply with its obligation to notify affected people at the first reasonable opportunity. This was because it didn’t implement a process to notify people about the details of what personal health information was compromised without requiring them to make a formal access request.

Patricia Kosseim, Information and Privacy Commissioner of Ontario commented:

> “Personal health information is particularly sensitive and privacy breaches can have devastating impacts for individuals.”

The regulator said it was important for the report to be made public after four years of resistance by LifeLabs. We agree that it is important that we know how companies are protecting our data, especially the medical kind. But at the same time we also know that many organizations in the healthcare industry do not have the staff to handle this, not do they have the funding to hire those staff. It’s catch 22.

At the time, LifeLabs wrote in an open letter that the cybersecurity firm it hired to investigate the incident advised it that the risk to its customers in connection with this cyberattack was low. LifeLabs said it hadn’t seen any public disclosure of customer data as part of its investigations, including monitoring of the dark web and other online locations.

Malwarebytes checked up whether that claim still held through and could indeed not find any LifeLabs customer data that came from that breach.

The reason is not a big mystery. Reportedly, LifeLabs paid the ransomware group, which is why it’s still unknown which group was behind the attack. The specific amount of the ransom paid has not been disclosed by the company.

But as ransomware groups are just a gang of criminals, it might be hard to take their word for it that they won’t release the data at some point. We will keep an eye on it.

Researchers reveal major vulnerabilities in popular corporate VPN clients, allowing remote attacks. Discover the NachoVPN tool and expert advisories to mitigate these critical security risks.

In a recent presentation at SANS HackFest Hollywood 2024, cybersecurity researchers at London, England-based firm AmberWolf have revealed critical security vulnerabilities in widely used corporate Virtual Private Network (VPN) clients allowing attackers to target macOS and Windows systems.

These vulnerabilities, found in both traditional SSL-VPN clients and modern Zero Trust solutions, could be exploited by attackers to gain remote code execution and elevated privileges on end-user devices.

The researchers found that VPN clients, while essential for secure remote access, often have deep system access. This makes them attractive and possibly a lucrative target for hackers.

The main problem lies in how these clients trust VPN servers. Attackers can create malicious VPN servers that exploit this trust, allowing them to run commands and gain administrator-level access to a user’s computer with little to no user interaction.

****NachoVPN****

To help the security community understand and mitigate these risks, the researchers have released NachoVPN, an open-source tool that simulates the attack scenarios discussed in their presentation. This tool acts as a malicious VPN server and shows how it can exploit weaknesses in different VPN clients. NachoVPN is designed to be easy to use and can be adapted to test for new vulnerabilities as they are discovered.

_“_NachoVPN serves as a proof-of-concept tool to simulate rogue VPN servers capable of exploiting these vulnerabilities, AmberWolf researchers wrote in their blog post. _“_It showcases how insecure behaviours in VPN clients can be leveraged to gain privileged code execution._“_

Alongside NachoVPN, the researchers have published detailed advisories documenting the specific vulnerabilities disclosed during their presentation. These advisories provide technical descriptions, attack vectors, and mitigation recommendations to help organizations protect themselves against these threats.

****Vulnerabilities****

The vulnerabilities affect popular corporate VPN clients, including Palo Alto GlobalProtect and SonicWall NetExtender for Windows. The advisories, identified as CVE-2024-5921 and CVE-2024-29014, highlight the risks of remote code execution and privilege escalation via malicious VPN servers.

****NachoVPN on GitHub****

For more information about NachoVPN and the disclosed vulnerabilities, interested parties can visit the project’s **GitHub** repository and review the detailed advisories. The researchers’ presentation from SANS HackFest Hollywood 2024 is also available on the SANS YouTube channel, providing further insights into their findings and recommendations.

AmberWolf Launches NachoVPN Tool to Tackle VPN Security Risks

Over the past year, "Matrix" has used publicly available malware tools and exploit scripts to target weakly secured IoT devices — and enterprise servers.

A Russian script kiddie using little more than publicly available malware tools and exploits targeting weak credentials and configurations has assembled a distributed denial-of-service (DDoS) botnet capable of disruption on a global scale.

In assembling the botnet, the attacker has targeted not just vulnerable Internet-of-Things (IoT) devices, as is the common practice these days, but also enterprise development and production servers, significantly increasing its potential for widespread disruption.

**Matrix Unleashed**

The attacker, whom researchers at Aqua Nautilus are tracking as "Matrix" after spotting the campaign recently, has established a store of sorts on Telegram, where customers can buy different DDoS plans and services. These include plans ranging from "Basic" to "Enterprise" that allow purchasers to unleash DDoS attacks of different durations at the transport and applications layers of targets of their choice.

"Although this campaign does not use advanced techniques, it capitalizes on widespread security gaps across a range of devices and software," said Assaf Morag, lead data analyst at Aqua in a blog post this week. "The simplicity of these methods highlights the importance of addressing fundamental security practices, such as changing default credentials, securing administrative protocols, and applying timely firmware updates, to protect against broad, opportunistic attacks like this one."

DDoS attacks have been a standard item in attacker playbooks for a long time. Though organizations have generally gotten better at dealing with them over the years, DDoS attacks remain hard to protect against entirely. Threat actors have continuously increased the volume and duration of DDoS attacks while developing techniques to target different layers of the network to maximize their disruptive impact. A Gcore study released earlier this year showed a 46% increase in DDoS attacks in the first half of 2024 compared with the same period last year. Some attacks peaked in excess of multiple terabits of attack traffic per second.

Matrix's campaign appears to have launched in November 2023 with the creation of a GitHub account. The attacker has been using the account primarily as a repository for various publicly available malware tools downloaded from different sources and which, in some cases, Matrix then modified for use in the DDoS campaign.

**Off-the-Shelf Attack Tools**

Aqua's analysis of Matrix's GitHub account showed a collection of commonly available DDoS botnet tools, including perennial favorite Mirai, DDoS agent, Pybot, Pynet, SSH Scan Hacktool, and Discord Go. Most of these tools are publicly available and open source; what distinguishes Matrix is how it's been able to integrate and use these tools effectively in assembling a DDoS botnet. "Instead of forking repositories, the tools are downloaded and modified locally, suggesting a level of customization and adaptability," Morag said.

Matrix has been using the tools to scan the Internet for IoT devices with known vulnerabilities in them that the owners have left unpatched. Many of the vulnerabilities that the threat actor's attack scripts scan for are older flaws, including one from 2014 (CVE-2014-8361) a remote code execution (RCE) vulnerability in Realtek Software Development Kit.

Aqua listed vulnerabilities the attacker is targeting, including three from 2017 (CVE-2017-17215, CVE-2017-18368, and CVE-2017-17106); another three targeted vulnerabilities are from 2018 (CVE-2018-10561, CVE-2018-10562, and CVE-2018-9995). The vulnerabilities affect a range of Internet-connected devices including network routers, DVRs, cameras, and telecom equipment.

And in something of a departure from typical DDoS campaigns, the threat actor is scanning the IP ranges of several cloud service providers for vulnerabilities and misconfigurations in telnet, SSH, Hadoop YARN, and other enterprise servers. One of the vulnerabilities that Matrix has targeted is CVE-2024-27348, a critical RCE vulnerability in Apache HugeGraph servers. Nearly half (48%) the scanning activity that Aqua observed targeted servers in AWS environments, 34% were in Microsoft Azure, and 16% on Google's cloud platform. For the moment at least, Matrix's primary focus appears to be China and Japan, likely due to the high density of IoT devices in those countries, Morag said.

**Brute-Force Attacks**

As is common in most such campaigns, Matrix has also been taking advantage of default and weak passwords and misconfigurations to compromise IoT devices and enterprise servers and making them part of the DDoS botnet. Aqua found Matrix using a brute-force script against 167 username and password pairs that organizations had used to secure access to their IoT and server environments. A startling 134 of the pairs granted root or admin level access on affected devices.

Aqua's analysis showed there are 35 million systems running the software that the attacker appears to be targeting. Not all of them are vulnerable. But if even if just 1% are exploitable, that would give the attacker a botnet of around 350,000 devices.

In comments to Dark Reading, Morag says only content delivery networks and organizations with visibility into Internet traffic logs can really say what the actual size of the botnet that Matrix has assembled. But indications are that it is large. "We have hundreds of honeypots, and we usually see an attack/campaign on one or two types of honeypots. But in this case, we saw attacks on our SSH, Telnet, Jupytar Lab, Jupytar Notebook, Hadoop, HugeGraph, and a few simulators of IoT devices," which is unusual, he says. "In addition, the attacker utilized some of our honeypots to attack Telnet and SSH, with a 95% success rate."

Russian Script Kiddie Assembles Massive DDoS Botnet

Enterprise cybersecurity teams tell Omdia's Maxine Holt that they want to dig out from underneath mounting tech and pivot to a simpler platform model — but they are finding that tricky to pull off.

Omdia's survey of cybersecurity leaders demonstrated that they're currently in a conundrum — drowning in security products they want to pare down but instead having to add layers to cope with the exploding threat landscape.

It's a challenge they are looking at cybersecurity platforms to solve, but it's going to take time.

Maxine Holt, who leads the Omdia cybersecurity research group, joined the Dark Reading News Desk at Black Hat USA 2024 fresh off the Omdia Summit, where her team of analysts presented the detailed results of their 2024 survey of cybersecurity decision-makers. They found the typical organization is running somewhere between 21 to 50 separate cybersecurity tools. And while three-quarters of organizations indicated they were interested in cutting that number down to a more manageable number, 87% of respondents had nonetheless added tools to their systems over the past year.

"They're struggling with the threat landscape," Holt said. "It's not as easy as unplugging one thing and plugging in something else."

These organizations will have the opportunity to migrate over to a cybersecurity platform over the next three to five years, as their contracts sunset, according to the survey.

Major players in the cybersecurity platform space, including CrowdStrike, Palo Alto Networks, Fortinet, and Check Point, stand to gain market share in the next few years as the shift occurs, but Holt stressed the need for a healthy ecosystem of vendors.

"We have to support the thousands of vendors in the space so they can innovate," Holt said.

News Desk 2024: The Rise of Cybersecurity Platforms

GenAI's 30%-50% coding productivity boost comes with a downside — it's also generating vulnerabilities. Veracode's Chris Wysopal talks about what he finds out in this News Desk interview during Black Hat USA.

It's faster, for sure, but generative artificial intelligence (GenAI) is learning how to code just like a human developer would — and that means picking up mistakes along the way.

GenAI and large language models (LLMs) learn how to code based off of open source models, which themselves are flawed, explained Chris Wysopal, CTO and co-founder of Veracode, at this year's Dark Reading News Desk at Black Hat USA 2024.

"\[GenAI\] can write a lot more code a lot faster," he said. "So what you end up with is more code and more vulnerabilities per unit of time."

The trick then becomes finding and fixing vulnerabilities at the same pace.

In his research presented at the conference, "From HAL to HALT: Thwarting Skynet's Siblings in the GenAI Coding Era" (a titled itself written by an LLM), Wysopal proposes the best way forward is using AI to find and fix the vulnerabilities in AI-generated software code. But we're not there yet.

According to research, the current model that can write code the best is an LLM called StarCoder. That's not to say it writes code completely free of vulnerabilities, but it's the best thing going. ChatGPT 4.0 and ChatGPT 2.5 were also found to be fairy adept at writing secure code.

"A general purpose LLM can fix some security bugs, but it turns out it's not great at it," Wysopal says. "And so we're seeing specialized LLMs that are trained just to secure code."

Wysopal and his team at Veracode are working on that, as well as other companies, he adds.
