This is a post from HackRead.com Read the original post: IT and Cybersecurity Jobs in the Age of Emerging AI Technologies

Artificial intelligence (AI) is rapidly transforming industries, and IT and cybersecurity are no exception. While some fear AI replacing human workers, the reality is far more subtle. AI will undoubtedly automate tasks, but it will also create entirely new job opportunities in both the IT and cybersecurity sectors.

According to the cybersecurity and IT certification exam practice platform Examice, the IT sector has become more lucrative than ever before due to the sudden emergence of AI applications. This growth has caused the need for skilled professionals capable of managing and securing AI-driven systems.

ISC2’s AI Cyber 2024 study also reveals a strong sense of optimism among respondents, with 82% expressing belief in AI’s potential to enhance job efficiency. Additionally, 56% anticipate AI streamlining certain job tasks, thereby allowing more time for tasks of higher value. However, there is a general concern among 75% of respondents regarding the potential misuse of AI for cyberattacks and other malicious purposes.

This article explores how AI will impact these fields and the skills that will be most in demand in the coming years.

****AI’s Impact on IT****

AI’s integration into IT optimises operational tasks and promotes innovation, allowing IT professionals to focus on more strategic initiatives. Here are three key impacts of AI on the IT sector:

*   **Automation of Mundane Tasks:** AI will take over repetitive tasks like server management, software configuration, and basic troubleshooting. This will free up IT professionals to focus on more strategic initiatives like cloud migration, data center optimization, and user experience design.
*   **Enhanced Network Management:** AI-powered tools will proactively monitor networks, identify potential issues, and even take corrective actions before problems arise. This will lead to increased network uptime and efficiency.
*   **The Rise of AI-powered Support:** Chatbots and virtual assistants powered by AI will handle routine user inquiries, freeing up IT staff to address more complex issues.

****New Opportunities in IT****

While adding innovation to the Information Technology sector AI is also creating new opportunities for professionals, job seekers and entrepreneurs. Here are three among countless opportunities that professionals are already taking advantage of, thanks to AI:

*   **AI Integration Specialists:** Businesses will need specialists to integrate AI solutions into existing IT infrastructure and ensure seamless operation.
*   **Data Scientists and Analysts:** The vast amount of data generated by AI systems will require skilled data scientists to analyze it and extract valuable insights.
*   **IT Security Specialists for AI:** As AI becomes more prevalent, securing these systems against cyberattacks will be crucial. This will create a demand for IT security professionals with expertise in AI vulnerabilities.

****AI and Cybersecurity****

Cybersecurity is already a lucrative sector. While hackers can earn big bucks, they also protect and serve their countries by protecting their critical infrastructure from devastating cyber attacks.

It is also a fact that as the cybersecurity sector grows the same can be said about cyber attacks and cyber criminals. Here are 6 key things AI can or is already helping organisations with:

*   **AI-powered Threat Detection:** AI can analyze network traffic patterns and identify malicious activity with greater accuracy and speed than traditional methods. This will be crucial in the fight against increasingly sophisticated cyberattacks.
*   **Vulnerability Detection:** AI can continuously scan systems for vulnerabilities and recommend patches before attackers can exploit them.
*   **AI-driven Phishing Detection:** AI can analyze emails and identify subtle language cues that might indicate a phishing attempt.

*   **Expertise in AI Security:** Understanding how AI systems work and the specific security challenges they pose will be essential.
*   **Human-AI Collaboration:** Security professionals will need to be adept at working alongside AI tools to leverage their combined strengths.
*   **Strong Analytical Skills:** The ability to analyze data and identify security threats will remain a critical skill.

****The Future is Bright****

The rise of AI will undoubtedly change the future of the IT and cybersecurity sectors. However, these changes will not lead to widespread job displacement. Instead, AI will create new opportunities for professionals who are willing to adapt and develop the skills needed to thrive in this evolving environment.

However, cybercriminals are also monitoring the rise of AI. Malicious versions of AI chatbots, such as WormGPT and FraudGPT, are prime examples. Therefore, authorities must take necessary measures to prevent the misuse of AI, while simultaneously fostering its beneficial applications in the IT and cybersecurity domains.

COMMENTARY

Foreign adversaries have attempted to disrupt the US elections for years through various methods. This includes espionage and "hack and leak" campaigns that steal sensitive data and later amplify it in public forums. Today, generative AI (GenAI) is altering the battlefield for attacks, and in the modern information ecosystem where misinformation and disinformation can spread rapidly, it has the potential to transform geopolitics.

Throughout my 24-year career with the FBI, I witnessed sophisticated adversaries attempt to sow confusion and cripple networks, as cyber-threat actors developed tools and tactics to disrupt businesses, governments, and more. The malicious use and proliferation of GenAI in 2024 presents one of the toughest challenges we'll face in an election year. 

**Adversaries Continue on Their Path to Disrupt and Dismantle**

Nation-state adversaries affiliated with and tied to the motivations of foreign governments have the resources to scale operations, and pose a constant threat to democracy. As we've seen previously, it's likely that threat actors from China, Russia, and Iran (charged for sending fake, intimidating emails to US voters in 2020) will seek to interfere with the 2024 US election.

Adversaries may seek to target actual election infrastructure itself, including the hardware and software used to tally and transmit votes, as well as political campaign assets. While some actors have leveraged information operations, generative AI is poised to increase the attractiveness of this malicious activity. With GenAI, it is easier than ever for threat actors to create content and influence narratives that support their underlying goals and objectives. This, in turn, can undermine public confidence and perceptions of political issues, parties, and candidates.

In fact, we're already starting to see the impacts. Threat actors from China recently weaponized deepfakes ahead of Taiwan's election, aiming to increase the voting public's confidence in candidates more diplomatic to China. Fabricated information campaigns stemming from state-nexus entities will not be novel in 2024; however, generative AI will make deciphering what is real or not infinitely more difficult. 

The rise of GenAI has also lowered the barrier of entry for virtually anyone to interfere with elections. Less sophisticated hackers or hacktivists with a specific geopolitical goal may be able to create high-quality disinformation campaigns with relative ease. We've already seen a local magician make global headlines this year by using AI to create fake robocalls, and it's only April.

**Countering These Growing Threats**

So, what can be done? When it comes to protecting the disparate election systems, it is critical to apply a risk-informed approach. At the heart of this is hardening environments to protect systems and stop breaches, 24/7 continuous monitoring of systems, and deep visibility into critical areas of risk, including endpoints, cloud, and identity. Employing both threat hunting and threat intelligence is equally as important, as these tools help to proactively protect against adversaries who may attempt to penetrate networks.

State and local elections administration entities have improved their security over the past several election cycles. So too have political parties and campaign entities. But additional attention and investment is warranted.

With respect to information operations, we must continue to raise awareness. Defending against this threat starts with vigilance from everyone. Citizens must be on alert and validate the origin of information they are consuming, consider the source's political stance and objective, and attempt to validate information through trusted sources prior to amplifying it. All Americans have a crucial role to play in critically analyzing the information they are getting and, more importantly, sharing 

Social media companies and GenAI companies should work to detect and prevent threat actors' use of their tools and platform. At a minimum this means cooperating with each other where appropriate and collaborating with cybersecurity companies and IT providers that have experience tracking these groups.

In 2024, voters in all 50 states and across 55 countries will participate in elections, providing numerous opportunities for adversaries with various motivations to disrupt and dismantle confidence in democracy. With proper awareness, preparation, and cybersecurity best practices in place, we can take a big step forward in defending democracy in the digital age. Failure to do so could be catastrophic.

AI Lowers Barrier for Cyber-Adversary Manipulation in 2024 Election

Malformed DOS paths in file-naming nomenclature in Windows could be used to conceal malicious content, files, and processes.

BLACK HAT ASIA – Singapore – A known issue associated with the DOS-to-NT path conversion process in Windows opens up significant risk for businesses by allowing attackers to gain rootkit-like post-exploitation capabilities to conceal and impersonate files, directories, and processes.

That's according to Or Yair, security researcher at SafeBreach, who outlined the issue during a session here this week. He also detailed four different vulnerabilities related to the issue, which he dubbed "MagicDot" - including a dangerous remote code-execution bug that can be triggered simply by extracting an archive.

**Dots & Spaces in DOS-to-NT Path Conversion**

The MagicDot group of problems exist thanks to the way that Windows changes DOS paths to NT paths.

When users open files or folders on their PCs, Windows accomplishes this by referencing the path where the file exists; normally, that's a DOS path that follows the "C:\\Users\\User\\Documents\\example.txt" format. However, a different underlying function called NtCreateFile is used to actually perform the operation of opening the file, and NtCreateFile asks for an NT path and not a DOS path. Thus, Windows converts the familiar DOS path visible to users into an NT path, prior to calling NtCreateFile to enable the operation.

The exploitable problem exists because, during the conversion process, Windows automatically removes any periods from the DOS path, along with any extra spaces at the end. Thus, DOS paths like these:

*   C:\\example\\example<space>    
    

are all converted to "\\??\\C:\\example\\example" as an NT path.

Yair discovered that this automatic stripping out of erroneous characters could allow attackers to create specially crafted DOS paths that would be converted to NT paths of their choice, which could then be used to either render files unusable or to conceal malicious content and activities.

**Simulating an Unprivileged Rootkit**

The MagicDot issues first and foremost create the opportunity for a number of post-exploitation techniques that help attackers on a machine maintain stealth.

For instance, it's possible to lock up malicious content and prevent users, even admins, from examining it. "By placing a simple trailing dot at the end of a malicious file name or by naming a file or a directory with dots and/or spaces only, I could make all user-space programs that use the normal API inaccessible to them ... users would not be able to read, write, delete, or do anything else with them," Yair explained in the session.

Then, in a related attack, Yair found that the technique could be used to hide files or directories within archive files.

"I simply ended a file name in an archive with a dot to prevent Explorer from listing or extracting it," Yair said. "As a result, I was able to place a malicious file inside an innocent zip — whoever used Explorer to view and extract the archive contents was unable to see that file existed inside."

A third attack method involves masking malicious content by impersonating legitimate file paths.

"If there was a harmless file called 'benign,' I was able to \[use DOS-to-NT path conversion\] to create a malicious file in the same directory \[also named\] benign," he explained, adding that the same approach could be used to impersonate folders and even broader Windows processes. "As a result, when a user reads the malicious file, the content of the original harmless file would be returned instead," leaving the victim none the wiser that they were actually opening malicious content.

Taken together, manipulating MagicDot paths can grant adversaries rootkit-like abilities without admin privileges, explained Yair, who published detailed technical notes on the attack methods in tandem with the session.

"I found I could hide files and processes, hide files in archives, affect prefetch file analysis, make Task Manager and Process Explorer users think a malware file was a verified executable published by Microsoft, disable Process Explorer with a denial of service (DoS) vulnerability, and more," he said — all without admin privileges or the ability to run code in the kernel, and without intervention in the chain of API calls that retrieve information.

"It's important that the cybersecurity community recognize this risk and consider developing unprivileged rootkit detection techniques and rules," he warned.

**A Series of "MagicDot" Vulnerabilities**

During his research into the MagicDot paths, Yair also managed to uncover four different vulnerabilities related to the underlying issue, three of them since patched by Microsoft.

One remote code execution (RCE) vulnerability (CVE-2023-36396, CVSS 7.8) in Windows's new extraction logic for all newly supported archive types allows attackers to craft a malicious archive that would write anywhere they choose on a remote computer once extracted, leading to code execution.

"Basically, let's say you upload an archive to your GitHub repository advertising it as a cool tool available for download," Yair tells Dark Reading. "And when the user downloads it, it's not an executable, you just extract the archive, which is considered a completely safe action with no security risks. But now, the extraction itself is able to run code on your computer, and that is seriously wrong and very dangerous."

A second bug is an elevation of privilege (EoP) vulnerability (CVE-2023-32054, CVSS 7.3) that allows attackers to write into files without privileges by manipulating the restoration process of a previous version from a shadow copy.

The third bug is Process Explorer unprivileged DOS for anti-analysis bug, for which CVE-2023-42757 has been reserved, with details to follow. And the fourth bug, also an EoP issue, allows unprivileged attackers to delete files. Microsoft confirmed that the flaw led to "unexpected behavior" but hasn't yet issued a CVE or a fix for it.

"I create a folder inside the demo folder called …<space> and inside, I write a file named c.txt," Yair explained. "Then when an administrator attempts to delete the …<space> folder, the entire demo folder is deleted instead."

**Potentially Wider "MagicDot" Ramifications**

While Microsoft addressed Yair's specific vulnerabilities, the DOS-to-NT path conversion auto-stripping of periods and spaces persists, even though that's the root cause of the vulnerabilities.

"That means there might be many more potential vulnerabilities and post-exploitation techniques to find using this issue," the researcher tells Dark Reading. "This issue is still exists and can lead to many more issues and vulnerabilities, which can be much more dangerous than the ones we know about."

He adds that the problem has ramifications beyond Microsoft.

"We believe the implications are relevant not only to Microsoft Windows, which is the world's most widely used desktop OS, but also to all software vendors, most of whom also allow known issues to persist from version to version of their software," he warned in his presentation.

Meanwhile, software developers can make their code safer against these types of vulnerabilities by utilizing NT paths rather than DOS paths, he noted.

"Most high-level API calls in Windows support NT paths," Yair said in his presentation. "Using NT paths avoids the conversion process and ensures the provided path is the same path that is being actually operated on."

For businesses, security teams should create detections that look for rogue periods and spaces within file paths.

"There are pretty easy detections that you can develop for these, to look for files or directories, that have trailing dots or spaces in them, because if you find those, on your computer, it means that someone did it on purpose because it's not that easy to do," Yair tells Dark Reading. "Normal users can't just create a file with ends with a dot or space, Microsoft will prevent that. Attackers will need to use a lower API that is closer to the kernel, and will need some expertise to accomplish this."

'MagicDot' Windows Weakness Allows Unprivileged Rootkit Activity

The local phone and business communications company said that attackers accessed unspecified PII, after infiltrating its internal networks.

Texas-based Frontier Communications, which provides local residential and business telecom services in 25 states, has shut down its operations in the wake of a cyberattack that resulted in the theft of personally identifiable information (PII).

The breach occurred four days ago on April 14, when it detected a breach by an unauthorized third party who had gained access to "portions of its information technology environment," according to an incident filing with the US Securities & Exchange Commission (SEC).

As part of its containment efforts, Frontier took "certain of the company's systems \[offline, which\] resulted in an operational disruption that could be considered material." It reported that while its core IT environment is up and running, normal business operations have yet to resume; and as of this writing, the telco's website was still offline.

Frontier didn't disclose what PII the cyberattacker accessed or who's affected, nor the suspected nature of the adversary. Telecom companies are a popular target for both financially motivated attackers as well as advanced persistent threats (APT), given the rich data repositories they hold. For instance, the Sandman APT was behind a prolific string of attacks last fall bent on stealing call-data records, mobile subscriber identity data, and metadata from carrier networks.

"The company continues to investigate the incident, has engaged cybersecurity experts, and has notified law enforcement authorities," according to the SEC filing. "The company does not believe the incident is reasonably likely to materially impact the company's financial condition or results of operations."

Cyberattack Takes Frontier Communications Offline

It turns out that a powerful security solution can double as even more powerful malware, capable of granting comprehensive access over a targeted machine.

A creative exploit of Palo Alto Networks' extended detection and response (XDR) software could have allowed attackers to puppet it like a malicious multitool.

In a briefing at Black Hat Asia this week, Shmuel Cohen, security researcher at SafeBreach, described how he not only reverse-engineered and cracked into the company's signature Cortex product but also weaponized it to deploy a reverse shell and ransomware.

All but one of the weaknesses associated with his exploit have since been mended by Palo Alto. Whether other, similar XDR solutions are vulnerable to a similar attack is as yet unclear.

**A Devil's Bargain in Cybersecurity**

There is an inescapable devil's bargain when it comes to using certain kinds of far-reaching security tools. In order for these platforms to do their jobs, they must be granted highly privileged carte blanche access over every nook and cranny in a system.

For instance, to perform real-time monitoring and threat detection across IT ecosystems, XDR demands the highest possible permissions, and access to very sensitive information. And, to boot, it can't be easily removed. It was this immense power wielded by these programs that inspired in Cohen a twisted idea.

"I thought to myself: Would it be possible to turn an EDR solution itself into malware?" Cohen tells Dark Reading. "I'd take all these things that the XDR has and use them against the user."

After picking a laboratory subject — Cortex — he began reverse-engineering its various components, trying to figure out how it defined what is and isn't malicious.

A lightbulb switched on when he discovered a series of plaintext files the program relied on more than most.

**How to Turn XDR Evil**

"But those rules are inside my computer," Cohen thought. "What would happen if I manually removed them?"

It turned out that Palo Alto had thought of this already. An anti-tampering mechanism prevented any user from touching those precious Lua files — except the mechanism had an Achilles' heel. It worked by protecting not each individual Lua file by name, but the folder that encapsulated them all. To reach the files he wanted, then, he wouldn't have to undo the anti-tampering mechanism, if he could just reorient the path used to reach them and bypass the mechanism altogether.

A simple shortcut probably wouldn't have sufficed, so he used a hard link: the computer's way of connecting a filename with the actual data stored on a hard drive. This allowed him to point his own new file to the same location on the drive as the Lua files.

"The program was not aware that this file was pointing to the same location in the hard disk as the original Lua file, and this allowed me to edit the original content file," he explains. "So I created a hard link to the files, edited and removed some rules. And I saw that as I removed them — and did another little thing that caused the app to load new rules—I could load a vulnerable driver. And from there, the whole computer was mine."

After taking complete control in his proof of concept attack, Cohen recalls, "What I did first was change the protection password on the XDR so it cannot be removed. I also blocked any communication to its servers."

Meanwhile, "Everything seems like it's working. I can hide the malicious activities from the user. Even for an action which would've been prevented, the XDR won't provide a notification. The endpoint user will see the green marks that indicate everything is OK, while underneath I'm running my malware."

The malware he decided to run was, first, a reverse shell, enabling full control over the targeted machine. Then he successfully deployed ransomware, right under the program's nose.

**The Fix Palo Alto Didn't Make**

Palo Alto Networks was receptive to Cohen's research, working closely with him to understand the exploit and develop fixes.

There was one vulnerability in his attack chain, however, that they chose to leave as is: the fact that Cortex's Lua files are stored entirely in plaintext, with no encryption whatsoever, despite their highly sensitive nature.

That seems alarming, but the reality is that encryption wouldn't be much of a deterrent for attackers, so after discussing the matter, he and the security company agreed that they didn't need to change that. As he notes, "The XDR eventually needs to understand what to do. So even if it's encrypted, at some point in its operation it will need to decrypt those files in order to read them. So attackers could just catch the content of the files then. It would be one more step for me in order to read those files, but I can still read them."

He also says that other XDR platforms are likely susceptible to the same kind of attack.

"Other XDRs will implement this differently, maybe," he says. "Maybe the files will be encrypted. But no matter what they will do, I can always bypass it."

Evil XDR: Researcher Turns Palo Alto Software Into Perfect Malware

The cybersecurity industry has no shortage of problems: Attackers are using automation to shorten their time to exploit, patching software is burdensome, establishing defenses such as segmentation remains difficult, and a shortage of cybersecurity-skilled workers holds back efforts in all of these areas.

No wonder, then, that Cisco has decided to launch an AI-powered, distributed security platform for protecting cloud workloads and artificial intelligence (AI) systems from cybersecurity threats. Dubbed Hypershield, the platform will push security out to the edge, using AI-augmented agents to maintain security controls around every workload in the data center and even distributed, connected devices. Cisco says the platform will be able to patch environments automatically, test software updates within the environment using simulated systems known as digital twins, and block attacks by detecting anomalous behavior.

Hyperbole was not in short supply, and "reimagined" seemed to be the word of the day.

Jeetu Patel, executive vice president and general manager of Cisco's security and collaboration division, called it "one of the largest platform shifts that we've experienced during our lifetimes."

"For the past gazillion years, when we've looked at security, the advantage has always been on the side of the adversary," Patel said during a press conference announcing Hypershield. "We are now approaching an era ... where ... because \[of this platform\], you might have a world where you might have an advantage as a defender, and wouldn't that be a wonderful world to live in."

Cybersecurity is certainly a field that could benefit from using AI for augmentation or as an assistant, and pushing security to the distributed edge — closer to the devices to be secured — can help simplify some aspects of vast networks that need to be secured.

The company's choice of technologies makes sense, says David Holmes, a principal analyst with Forrester Research. By using eBPF, a technology that allows sandboxed programs to run in a privileged context, pieces of the workload can be instrumented, and data processing units (DPUs) allow efficient processing of data using high-bandwidth network interfaces.

"They are describing a more modern approach to building a private cloud data center architecture, and that’s good," Holmes says. "eBPF for automation \[and\] security, container-like workloads — their DPUs — overall, this is good for the industry if they pull it off."

**Digital Twins Allow Automated Patching**

Craig Connors, chief technology officer of Cisco's security business group, demonstrated how a workload or application could be automatically patched and run in parallel using digital-twin technology to test the stability and correctness of the updated software. Digital twins are simulations — originally used in product development and manufacturing — that allow software engineers to test and observe a version of a device or application.

If patched code passes all tests and satisfies policies, then it can be promoted to production, Connors said during the demonstration.

"What we've done is we've essentially introduced the digital twin into every enforcement point that we deploy," Connors stated. "So we're actually bringing CI/CD \[continuous integration and continuous delivery\] to the embedded world by running the end-of-the-promotion pipeline as a digital twin on every single enforcement point for every single customer in the world in a transparent way. That allows us to test every possible combination that could happen in your real environment everywhere."

While the company will start with Linux environments, Cisco hinted at future plans to support other operating systems.

The same digital-twin approach can be applied to developing segmentation policies for networks of devices and workloads, according to Connors. The AI assistant built into the Hypershield platform could recommend microsegmentation policies and give a confidence score that each policy would behave well inside a given environment.

"Imagine if AI wasn't just recommending microsegmentation policies, but it was modeling them in a digital twin of your environment, and telling you exactly how it tested those policies to make sure they were correct before it recommended them to you," Connors said. "So we're really trying to bring that trust aspect in and not just 'AI bomb' you with recommendations."

**Distributed Exploit Protection**

Cisco says the platform will also protect against exploits in real time by using threat intelligence to inform anomaly detection and response. Because companies never know which vulnerabilities will be picked up by an attacker, the system allows all high-impact vulnerabilities to be treated the same.

This approach benefits companies with legacy hardware and software that has reached end of life and is no longer receiving updates, according to Connors.

"There are cases where we can never patch. ... Let's say the software's end of life, but my business still relies on it and a critical vulnerability exists," Connors said. "So while these are intended to be short-lived patches to bridge that gap between that availability and patch deployment and then we'll automatically pull back these distributed shields, it is potentially feasible that you may want to run this for the life of the application to continue protecting you against \[exploitation\]."

Having the vision and individual technologies is a good first step, but like the platform managing driver-assist features in cars, the trick is how it all comes together, says Jon Oltsik, analyst emeritus at Enterprise Strategy Group. Coordinating the pieces across multiple systems, rather than looking at each one in isolation — as well as figuring out "normal" activity — and then responding will be tricky.

"It's a good goal, but a lot of things need to come together to make it happen, including user buy-in," he says. "AI-based security must go through rigorous testing and be proven in the field before security professionals will trust it."

Cisco has promised the platform will be generally available by August.

Cisco's Complex Road to Deliver on Its Hypershield Promise

Attackers are indiscriminately targeting VPNs from Cisco and several other vendors in what may be a reconnaissance effort, the vendor says.

Source: Wright Studio via Shutterstock

Cisco Talos this week warned of a massive increase in brute-force attacks targeting VPN services, SSH services, and Web application authentication interfaces.

In its advisory, the company described the attacks as involving the use of generic and valid usernames to try and gain initial access to victim environments. The targets of these attacks appear to be random and indiscriminate and not restricted to any industry sector or geography, Cisco said.

The company identified the attacks as impacting organizations using Cisco Secure Firewall VPN devices and technologies from several other vendors, including Checkpoint VPN, Fortinet VPN, SonicWall VPN, Mikrotik, and Draytek.

**Attack Volumes Might Increase**

"Depending on the target environment, successful attacks of this type may lead to unauthorized network access, account lockouts, or denial-of-service conditions," a Cisco Talos statement explained. The vendor noted the surge in attacks began around March 28 and warned of a likely increase in attack volumes in the coming days.

Cisco did not immediately respond to a Dark Reading inquiry regarding the sudden explosion in attack volumes and whether they're the work of a single threat actor or multiple threat actors. Its advisory identified the source IP addresses for the attack traffic as proxy services associated with Tor, Nexus Proxy, Space Proxies, and BigMama Proxy.

Cisco's advisory linked to indicators of compromise — including IP addresses and credentials associated with the attacks — while also noting the potential for these IP addresses to change over time.

The new wave of attacks is consistent with the surging interest among threat actors in the VPNs and other technologies that organizations have deployed in recent years to support remote access requirements for employees. Attackers — including nation-state actors — have ferociously targeted vulnerabilities in these products to try and break into enterprise networks, prompting multiple advisories from the likes of the US Cybersecurity and Infrastructure Security Agency (CISA), the FBI, the National Security Agency (NSA), and others.

**VPN Vulnerabilities Explode in Number**

A study by Securin showed the number of vulnerabilities that researchers, threat actors, and vendors themselves have discovered in VPN products increased 875% between 2020 and 2024. They noted how 147 flaws across eight different vendors' products grew to nearly 1,800 flaws across 78 products. Securin also found that attackers weaponized 204 of the total disclosed vulnerabilities so far. Of this, advanced persistent threat (APT) groups such as Sandworm, APT32, APT33, and Fox Kitten had exploited 26 flaws, while ransomware groups like REvil and Sodinokibi had exploits for another 16.

Cisco's latest advisory appears to have stemmed from multiple reports the company received about password-spraying attacks targeting remote access VPN services involving Cisco's products and those from multiple other vendors. In a password-spraying attack, an adversary basically attempts to gain brute-force access to multiple accounts by trying default and common passwords across all of them.

**Reconnaissance Effort?**

"This activity appears to be related to reconnaissance efforts," Cisco said in a separate April 15 advisory that offered recommendations for organizations against password-spraying attacks. The advisory highlighted three symptoms of an attack that users of Cisco VPNs might observe: VPN connection failures, HostScan token failures, and an unusual number of authentication requests.

The company recommended that organizations enable logging on their devices, secure default remote access VPN profiles, and block connection attempts from malicious sources via access control lists and other mechanisms.

"What is important here is that this attack is not against a software or hardware vulnerability, which usually requires patches," Jason Soroko, senior vice president of product at Sectigo, said in an emailed statement. The attackers in this instance are attempting to take advantage of weak password management practices, he said, so the focus should be on implementing strong passwords or implementing passwordless mechanisms to protect access.

A security advisory issued this week by the Cybersecurity and Infrastructure Security Agency (CISA) alerts administrators of vulnerabilities in two industrial control systems devices — Unitronics Vision Series PLCs and Mitsubishi Electric MELSEC iQ-R Series.

CISA warned that the Unitronics Vision Series PLC controller is open to remote exploit due to its storage of passwords in a recoverable format. This vulnerability (CVE-2024-1480) was assigned a CVSS score of 8.7.

Unitronics has not responded to, or worked with, the agency to mitigate the issue, leaving networks with these devices open to cyberattack, according to CISA. The advisory recommends ensuring the controllers are not connected to the Internet, isolating them from business networks, protecting the devices behind firewalls, and using secure methods, like virtual private networks (VPNs), for remote access.

The remaining ICS vulnerabilities impact the Mitsubishi Electric Corporation MELSEC iQ-R CPU Module. A design flaw in the CPU, tracked under CVE-2021-20599, has been assigned a CVSS score of 9.1. The unit transmits passwords in cleartext, which are easily intercepted by adversaries.

The Mitsubishi MELSEC CPUs also harbor a trio of reported flaws that could allow a threat actor to compromise usernames, access the device, and deny access to legitimate users. These include: exposure of sensitive information (CVE-2021-20594, CVSS 5.9); insufficiently protected credentials (CVE-2021-20597, CVSS 7.4); and a restrictive account lockout mechanism (CVE-2021-20598, CVSS 3.7).

Mitsubishi is working to provide mitigations and workarounds for the issues. However, systems with these devices are unable to be updated with a fix, according to CISA. The agency advises administrators with these devices in their networks to shore up defenses with firewalls, remote access limitations, and IP address restrictions.

"Mitsubishi Electric has released the fixed version ... but updating the product to the fixed version is not available," the advisory said. "CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability."

ICS Network Controllers Open to Remote Exploit, No Patches Available

Existing AI technology can allow hackers to automate exploits for public vulnerabilities in minutes flat. Very soon, diligent patching will no longer be optional.

AI agents equipped with GPT-4 can exploit most public vulnerabilities affecting real-world systems today, simply by reading about them online.

New findings out of the University of Illinois Urbana-Champaign (UIUC) threaten to radically enliven what's been a somewhat slow 18 months in artificial intelligence (AI)-enabled cyber threats. Threat actors have thus far used large language models (LLMs) to produce phishing emails, along with some basic malware, and to aid in the more ancillary aspects of their campaigns. Now, though, with only GPT-4 and an open source framework to package it, they can automate the exploitation of vulnerabilities as soon as they hit the presses.

"I'm not sure if our case studies will help inform how to stop threats," admits Daniel Kang, one of the researchers. "I do think that cyber threats will only increase, so organizations should strongly consider applying security best practices."

**GPT-4 vs. CVEs**

To gauge whether LLMs could exploit real-world systems, the team of four UIUC researchers first needed a test subject.

Their LLM agent consisted of four components: a prompt, a base LLM, a framework — in this case ReAct, as implemented in LangChain — and tools such as a terminal and code interpreter.

The agent was tested on 15 known vulnerabilities in open source software (OSS). Among them: bugs affecting websites, containers, and Python packages. Eight were given "high" or "critical" CVE severity scores. There were 11 that were disclosed past the date at which GPT-4 was trained, meaning this would be the first time the model was exposed to them.

With only their security advisories to go on, the AI agent was tasked with exploiting each bug in turn. The results of this experiment painted a stark picture.

Of the 10 models evaluated — including GPT-3.5, Meta's Llama 2 Chat, and more — nine could not hack even a single vulnerability.

GPT-4, however, successfully exploited 13, or 87% of the total.

It only failed twice for utterly mundane reasons. CVE-2024-25640, a 4.6 CVSS-rated issue in the Iris incident response platform, survived unscathed because of a quirk in the process of navigating Iris' app, which the model couldn't handle. Meanwhile, the researchers speculated that GPT-4 missed with CVE-2023-51653 — a 9.8 "critical" bug in the Hertzbeat monitoring tool because its description is written in Chinese.

As Kang explains, "GPT-4 outperforms a wide range of other models on many tasks. This includes standard benchmarks (MMLU, etc.). It also seems that GPT-4 is much better at planning. Unfortunately, since OpenAI hasn't released the training details, we aren't sure why."

**GPT-4 Good**

As threatening as malicious LLMs might be, Kang says, "At the moment, this doesn't unlock new capabilities an expert human couldn't do. As such, I think it's important for organizations to apply security best practices to avoid getting hacked, as these AI agents start to be used in more malicious ways."

If hackers start utilizing LLM agents to automatically exploit public vulnerabilities, companies will no longer be able to sit back and wait to patch new bugs (if ever they were). And they might have to start using the same LLM technologies as well as their adversaries will.

But even GPT-4 still has some ways to go before it's a perfect security assistant, warns Henrik Plate, security researcher for Endor Labs. In recent experiments, Plate tasked ChatGPT and Google's Vertex AI with identifying samples of OSS as malicious or benign, and assigning them risk scores. GPT-4 outperformed all other models when it came to explaining source code and providing assessments for legible code, but all models yielded a number of false positives and false negatives.

Obfuscation, for example, was a big sticking point. "It looked to the LLM very often as if \[the code\] was deliberately obfuscated to make a manual review hard. But often it was just reduced in size for legitimate purposes," Plate explains.

"Even though LLM-based assessment should not be used instead of manual reviews," Plate wrote in one of his reports, "they can certainly be used as one additional signal and input for manual reviews. In particular, they can be useful to automatically review larger numbers of malware signals produced by noisy detectors (which otherwise risk being ignored entirely in case of limited review capabilities)."

GPT-4 Can Exploit Most Vulns Just by Reading Threat Advisories

The group gained access to the victim network by duping IT employees with high administrative-access privileges.

Researchers this week shared details of an attack campaign by the infamous FIN7 threat group that targeted a large US-based global automotive manufacturer.

FIN7, a Russian advanced persistent threat (APT) group, also known as Carbon Spider, ELBRUS, and Sangria Tempest, conducted a spear-phishing campaign in late 2023 that was spotted and ultimately halted by BlackBerry's threat and research team. The attackers identified IT employees with high admin-level rights and lured them in by impersonating an IP scanning tool with a malicious URL. Once the employees opened the link, the threat actor ran its Anunak backdoor, allowing them to "gain an initial foothold utilizing living off the land binaries, scripts, and libraries (lolbas)," BlackBerry researchers said in blog post detailing the attack.

BlackBerry said its threat and research team detected and disrupted the attack before FIN7 was able to launch the ransomware portion of the attack.

In the past, FIN7 has targeted US retail, hospitality, and restaurant sectors, though it is now branching out to defense, insurance, and transportation sectors. BlackBerry researchers believe that the threat group is now likely targeting larger entities, with the assumption that they will pay a higher ransom.

BlackBerry did not disclose the name of the targeted automotive manufacturer.
