The Lazarus Group has successfully exploited a zero-day vulnerability in Google Chrome to gain control of infected devices, highlighting the group's continued sophistication and adaptability as a threat actor. With its use of advanced tactics such as generative AI and social engineering, the group is evolving its attacks and remains a force to be reckoned with in the cybersecurity landscape.
The Lazarus Group has exploited a zero-day vulnerability in Google Chrome to gain control of infected devices. The attack vector involves tricking individuals into downloading a malicious game from a fake website that resembles a legitimate online platform. The vulnerability, CVE-2024-4947, was patched by Google in mid-May 2024, but the Lazarus Group has managed to weaponize it as a zero-day exploit. The attack campaign is believed to have commenced in February 2024 and involves gathering system information before determining if the machine is valuable enough to conduct further post-exploitation actions. The Lazarus Group's tactics are evolving, with the use of generative AI to promote malicious websites and phishing-style attacks.
In a recent development that sheds light on the tactics employed by North Korean threat actors, Kaspersky has revealed that the Lazarus Group has successfully exploited a zero-day vulnerability in Google Chrome to gain control of infected devices. This sophisticated social engineering campaign is part of a broader pattern of attacks attributed to the Lazarus Group, which has been active in the cybersecurity landscape for several years.
The attack vector used by the Lazarus Group involves tricking individuals into downloading a malicious game from a fake website that resembles a legitimate online platform. The website, dubbed "detankzone[.]com," appears to be a professionally designed product page for a decentralized finance (DeFi) NFT-based multiplayer online battle arena (MOBA) tank game. However, upon closer inspection, the website contains a hidden script that runs in the user's Google Chrome browser, launching a zero-day exploit and giving the attackers complete control over the victim's PC.
The vulnerability in question is CVE-2024-4947, a type confusion bug in the V8 JavaScript and WebAssembly engine that was patched by Google in mid-May 2024. Despite this, the Lazarus Group has managed to weaponize the vulnerability as a zero-day exploit, allowing them to bypass security controls and gain unauthorized access to infected devices.
The attack campaign is believed to have commenced in February 2024, with successful exploitation resulting in the threat actor running a validator that takes the form of shellcode responsible for gathering system information. This information is then used to determine if the machine is valuable enough to conduct further post-exploitation actions. However, the exact payload delivered after this stage remains unknown.
It is worth noting that the Lazarus Group has been linked to other sophisticated attacks attributed to North Korean threat actors, including the Moonstone Sleet cluster. These attacks typically involve approaching prospective targets through email or messaging platforms, tricking them into installing a game by posing as a blockchain company or a game developer seeking investment opportunities.
The use of malicious tank games as a conduit to deliver malware is a tactic that has been observed in other North Korean threat actor campaigns. Microsoft has previously attributed similar attacks to the Moonstone Sleet cluster, highlighting the evolving tactics employed by these actors.
In this case, Kaspersky researchers have pointed out that the Lazarus Group's tactics are evolving and that they are constantly coming up with new, complex social engineering schemes. The use of generative AI is a notable example of this evolution, as the attackers have been observed using AI-generated content to promote their malicious websites.
The threat actor's activity has been observed across X (formerly Twitter) and LinkedIn, not to mention the specially-crafted websites and email messages sent to targets of interest. The website is also designed to lure visitors into downloading a ZIP archive ("detankzone.zip") that, once launched, is a fully functional downloadable game that requires player registration.
However, beneath the surface, this game harbors code to launch a custom loader codenamed YouieLoad, which was previously detailed by Microsoft. This indicates that the Lazarus Group has managed to steal the source code for the game from a legitimate blockchain play-to-earn (P2E) game named DeFiTankLand (DFTL), which suffered a hack of its own in March 2024.
The Lazarus Group's motivations appear to be centered around financial gain, with Kaspersky researchers noting that this group is "one of the most active and sophisticated APT actors" in the cybersecurity landscape. The attackers' tactics are indeed evolving, and their use of generative AI and other advanced technologies suggests a continued commitment to innovation.
In light of these findings, it is essential for individuals and organizations to remain vigilant and take steps to protect themselves against such attacks. This may involve staying up-to-date with the latest security patches and updates, as well as being cautious when interacting with unfamiliar websites or email attachments.
As the threat landscape continues to evolve, it will be crucial to monitor developments in this area and to stay informed about the tactics employed by actors like the Lazarus Group. By doing so, we can better prepare ourselves for potential threats and protect our digital assets from falling prey to sophisticated social engineering campaigns.
