Lazarus APT Hackers Exploit Chrome Zero-Day through Cryptocurrency Sport
The infamous Lazarus Superior Persistent Risk (APT) group has exploited a zero-day vulnerability within the Google Chrome browser, utilizing a cryptocurrency-themed sport as a lure.
The assault highlights the evolving ways of this North Korean-linked group, recognized for its monetary motivations and superior social engineering methods.
On Might 13, 2024, Kaspersky’s safety methods detected a brand new an infection on a private laptop in Russia, revealing the exploitation of a zero-day vulnerability in Google Chrome.
The assault was traced again to an internet site, detankzone[.]com, which masqueraded as a official product web page for a decentralized finance (DeFi) NFT-based multiplayer on-line battle enviornment (MOBA) tank sport.

Exploitation of Vulnerabilities
Nonetheless, beneath its seemingly innocuous facade lay a malicious script designed to use customers’ browsers and acquire management over their methods.
The exploit leveraged two vulnerabilities. The primary allowed attackers to learn and write reminiscence inside the Chrome course of, whereas the second bypassed the V8 sandbox, a safety characteristic designed to isolate reminiscence and forestall unauthorized code execution.
This refined assault enabled the hackers to execute arbitrary code on victims’ machines.
Upon discovering the exploit, Kaspersky promptly reported it to Google. Inside two days, Google launched an replace addressing the vulnerability (CVE-2024-4947) in Chrome model 125.0.6422.60.
Moreover, Google blocked entry to detankzone[.]com and associated malicious websites to guard customers from additional assaults.
Lazarus APT’s marketing campaign prolonged past technical exploits to incorporate elaborate social engineering efforts. The group constructed a social media presence to advertise their pretend sport, even reaching out to cryptocurrency influencers to amplify their attain.
This multifaceted strategy underscores Lazarus’s dedication to crafting convincing narratives round their assaults.
The attackers developed a seemingly official sport as a part of their deception technique. The sport, initially showing as a real product developed in Unity, was primarily based on stolen supply code from an present sport referred to as DeFiTankLand (DFTL).
This added layer of authenticity made the malicious marketing campaign extra credible and engaging to potential victims.
The Lazarus group’s use of zero-day vulnerabilities and superior social engineering ways poses vital threats to people and organizations. Their capability to adapt and innovate of their assault strategies means that such threats will persist and evolve.
Staying vigilant is essential for end-users. Frequently updating software program and exercising warning when interacting with unsolicited hyperlinks or downloads can mitigate dangers.
As browser builders proceed enhancing safety features like JIT compilers and sandboxes, customers are inspired to maintain their methods up to date to guard towards rising threats.
Risk actors proceed refining their strategies and leveraging new applied sciences, resembling generative AI for social engineering; cybersecurity measures should evolve accordingly to safeguard towards these refined assaults.
