Loading threat actor…
AppleJeus is a North Korea–linked threat actor and campaign cluster associated with the Lazarus ecosystem, commonly tracked as Citrine Sleet. Additional aliases include Gleaming Pisces, Storm-0139, Storm-1222, UNC1720, and UNC4736. The cluster is primarily associated with financially motivated operations against cryptocurrency exchanges, blockchain organizations, cryptocurrency engineers, and related Web3 targets. AppleJeus activity has used trojanized cryptocurrency applications and fake installers to establish access, including campaigns affecting macOS and other platforms. The cluster has also been associated with sophisticated exploitation and post-compromise tooling, including the FudModule kernel rootkit. Citrine Sleet exploited Chromium and Windows zero-day vulnerabilities to obtain code execution, escape browser sandboxing, elevate privileges, manipulate kernel memory, and deploy rootkit functionality. FudModule has employed vulnerable-driver abuse and direct exploitation of Windows kernel drivers, suppressed security and forensic controls, bypassed Protected Process Light protections, and injected payloads into privileged processes. AppleJeus-related activity is consistent with DPRK operations that generate illicit revenue through cryptocurrency theft and related financial cybercrime.

On August 19, 2024, Microsoft identified a North Korean threat actor exploiting a Chromium remote-code-execution (RCE) zero-day vulnerability ( CVE-2024-7971 )... Microsoft noted that Citrine Sleet used Chromium exploit to deploy a FudModule rootkit.
The RCE vulnerability was used to deploy a shellcode containing another exploit ( CVE-2024-38106 ) that was used to escape Chromium’s sandbox and deploy the downloaded FudModule rootkit into the memory.
