What it detects

This rule detects python.exe launched by a command interpreter that was itself started from a batch or PowerShell parent, matching the BAT to PowerShell to CMD to python execution tree of the Snake Python infostealer. Attackers use this chained launcher to unpack and run the Python stealer while blending into scripted activity. The interpreter-to-python lineage highlights the malware execution flow.
