What it detects

This rule detects a Python interpreter spawning a shell that invokes SUID privileged binaries, a behavior consistent with exploitation of the CopyFail vulnerability to gain root on modern Linux distributions. The child shell abuses setuid utilities to elevate an unprivileged process. Detecting this chain surfaces local privilege escalation attempts.
