McAfee Labs has recently uncovered a large scale CountLoader campaign that uses multiple layers of obfuscation and staged payload delivery to evade detection and maintain persistence in infected systems. The infection process relies on several layers of loaders, including PowerShell scripts, obfuscated JavaScript executed through mshta.exe, and in memory shellcode injection, each stage decrypting and launching the next. The attackers employ a custom encrypted communication protocol to interact with their C2 servers.
