HEAVYGRAM/CHOSEN BRICK Multi-stage Python implant execution
This rule detects potentially malicious activity by monitoring the execution of Python interpreters or specific suspicious executable names from within the C:\ProgramData directory. The detection logic focuses on processes launching from directories associated with configuration or data storage folders, often used by malware for staging or execution to avoid detection. It specifically flags Python execution involving certain suspicious file or argument strings, and the launch of named executables (e.g., RuntimeSSH.exe, smqdservice.exe) located in specific ProgramData subdirectories.
