RemotePE: The Lazarus RAT that lives in memory
Source AlienVault OTX General
Description
A sophisticated memory-only toolset used by a North Korean Lazarus subgroup targeting financial and cryptocurrency organizations consists of three malware families forming a chain. DPAPILoader decrypts and loads RemotePELoader from disk using Windows Data Protection API. RemotePELoader beacons to command-and-control servers and retrieves RemotePE, a fully-fledged remote access trojan executed entirely in memory without filesystem artifacts. The toolset employs environmental keying via DPAPI, EDR evasion through HellsGate technique and ETW patching, actor-in-the-loop payload delivery, and shared hosting infrastructure on Namecheap. RemotePE features comprehensive RAT capabilities including file operations, process management, command execution, and a plugin system for dynamically loading additional payloads, while maintaining persistence through masquerading as legitimate Windows services.
