In a concerning development, security researchers have uncovered a concerning trend of North Korean hackers exploiting a previously unknown zero day vulnerability in Google’s Chrome browser to target cryptocurrency firms and exchanges. This sophisticated zero day attack campaign, attributed to the notorious hacking group Citrine Sleet (also known as Hidden Cobra, UNC4736, and Diamond Sleet), highlights the ongoing cybersecurity threats posed by state-sponsored cybercriminals seeking financial gain to fund their regime through illicit means.
The Chrome Zero-Day Vulnerability: CVE-2024-7971
The Chrome zero-day vulnerability, identified as CVE-2024-7971, was discovered in Chrome’s V8 JavaScript and WebAssembly engine, allowing remote code execution by malicious actors. This zero day vulnerability enabled the North Korean hackers to bypass the browser’s security measures and gain SYSTEM privileges on targeted systems.
Advice from Microsoft
Keep operating systems and applications up to date. Apply security patches as soon as possible. Ensure that Google Chrome web browser is updated at version 128.0.6613.84 or later, and Microsoft Edge web browser is updated at version 128.0.2739.42 or later to address the CVE-2024-7971 vulnerability.

Citrine Sleet: A Prolific North Korean APT Actor
Citrine Sleet, also known as AppleJeus, Labyrinth Chollima, BlueNoroff, and Sapphire Sleet, is a well-known hacking collective with strong ties to North Korea’s Reconnaissance General Bureau (Bureau 121). This group has a long history of targeting the cryptocurrency industry, employing a range of tactics to infiltrate and steal digital assets.
The Exploit Chain
The cryptocurrency hackers’ modus operandi involved luring victims to malicious websites like the fake hacker site voyagorclub[.]space, where the Chrome exploit was delivered. Once the initial foothold was established, the attackers leveraged a Windows Kernel exploit, CVE-2024-38106, to escape the Windows sandbox and install a sophisticated FudModule rootkit using direct kernel object manipulation and kernel tampering.
Targeting Cryptocurrency Firms
Citrine Sleet’s primary focus has been on crypto industry attacks, as the group seeks to generate and launder funds to support the North Korean regime. Through the use of fake websites, bogus job offers on sites like LinkedIn crypto scams, and trojanized cryptocurrency wallets and trading apps, the hackers have successfully infiltrated numerous financial institutions managing cryptocurrency assets.
The Scope of the Attacks
According to Microsoft’s Threat Intelligence team, the exploited zero day vulnerability was discovered on August 19, 2024, and Google promptly released a fix on August 21 of the same year. However, the damage had already been done, with the North Korean ransomware managing to compromise an undisclosed number of cryptocurrency organizations during the window of opportunity.
Mitigating the Threat
To protect against such attacks, users are urged to update their Google Chrome browsers to the latest version, 128.0.6613.84 or higher, to avoid having google chrome hacked. Ensure Windows systems are equipped with the latest security patches. Additionally, enabling advanced security features in Microsoft Defender and other endpoint protection solutions can significantly enhance the defense against such sophisticated threats.
