In a sophisticated cyberattack, the North Korean threat actor group Lazarus has exploited a zero-day vulnerability in Google Chrome to steal cryptocurrency wallet credentials. The attack, uncovered by cybersecurity giant Kaspersky, involved a fake blockchain-based game designed to lure unsuspecting users.
Exploiting a Zero-Day Vulnerability
The attack was first identified by Kaspersky’s Global Research and Analysis Team in May 2024 and presented at the Security Analyst Summit 2024 in Bali. The Lazarus Group used a previously unknown bug in the V8 JavaScript engine of Google Chrome, which allowed them to execute arbitrary code, bypass security features, and conduct various malicious activities. Google has since patched the vulnerability following Kaspersky’s report.
Sophisticated Social Engineering
The attackers employed advanced social engineering techniques and generative AI to enhance the credibility of their fake game. The game, which invited users to compete globally with NFT tanks, was promoted through social media and LinkedIn, appearing genuine to potential victims. The hackers even created AI-generated images and engaged crypto influencers to further legitimize their scheme.
Significant Impact on Cryptocurrency Investors
The actual impact of the campaign could be extensive, affecting users and businesses worldwide. Shortly after the game’s launch on social media, the real game developers reported that $20,000 in cryptocurrency had been transferred from their wallets. The fake game mirrored the logo and visual quality of the original, making it difficult for users to distinguish between the two.
A Warning for the Crypto Community
Boris Larin, Principal Security Expert at Kaspersky, emphasized the dangers posed by such sophisticated attacks.
“With notorious actors like Lazarus, even seemingly innocuous actions—such as clicking a link on a social network or in an email—can result in the complete compromise of a personal computer or an entire corporate network,” Larin noted.
This incident serves as a stark reminder for the cryptocurrency community to remain vigilant and cautious of potential threats. Users are advised to keep their software updated, be wary of unsolicited links, and verify the authenticity of online promotions and games.
