PHANTOMPULSE RAT Uses UAC Bypass to Hijack Windows Systems

PHANTOMPULSE is a remote access trojan (RAT) used as a final payload in multi-stage attacks targeting Windows environments. It employs advanced post-exploitation techniques, including process injection, User Account Control (UAC) bypass, and a decentralized blockchain-based command-and-control (C2) mechanism. The malware utilizes three process injection techniques: module stomping, manual DLL mapping, and debug-driven execution. It avoids detection by using direct system calls instead of standard Windows APIs and incorporates a hardware breakpoint mechanism to disable security protections like AMSI and ETW. PHANTOMPULSE retrieves its C2 server address from Ethereum-based transaction data but has a vulnerability that allows defenders to hijack communication. It achieves persistence through scheduled tasks and supports self-healing capabilities. Privilege escalation is done using the "schuac" UAC bypass technique. The malware conducts system reconnaissance focusing on cryptocurrency wallets and messaging apps but does not directly steal credentials. It shows signs of AI-assisted development and shares tactics with DPRK-aligned threat groups, particularly in targeting cryptocurrency platforms.
