Citrine Slate: Prolific North Korean Actor
Citrine Sleet, also known as AppleJeus, Labyrinth Chollima, BlueNoroff, and Sapphire Sleet, is a well-known hacking group with strong ties to North Korea’s Reconnaissance General Bureau (Bureau 121). The group has a long history of targeting the cryptocurrency industry, employing a range of tactics to infiltrate and steal digital assets.
chain of exploitation
The crypto hackers’ modus operandi involved luring victims to malicious websites such as the fake hacker site voyagorclub(.)space, where Chrome was exploited. Once an initial foothold was established, the attackers exploited a vulnerability in the Windows Kernel, CVE-2024-38106, to escape the Windows sandbox and install a sophisticated rootkit FudModule using direct manipulation of kernel objects and kernel manipulation.
Targeting cryptocurrency companies
The Citrine Sleet group’s primary focus has been attacks on the crypto industry, with the group seeking to generate and launder funds to support the North Korean regime. Using fake websites, fake job offers on sites like LinkedIn crypto scams, hacked crypto wallets, and trading apps, the hackers have successfully infiltrated multiple financial institutions that manage crypto assets.
Range of attacks
According to Microsoft’s security intelligence team, the exploit 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, as North Korean ransomware managed to infiltrate an undisclosed number of cryptocurrency institutions during the window of opportunity.
Threat mitigation
To protect against such attacks, we urge users to update their Google Chrome browsers to the latest version, 128.0.6613.84 or higher, to avoid Google Chrome being compromised. Ensure that Windows systems are equipped with the latest security patches. Additionally, enabling advanced security features in Microsoft Defender and other endpoint protection solutions can significantly strengthen defense against such sophisticated threats.
