DET0258 Linux Python Startup Hook Persistence via .pth and Customize Files (T1546.018)
AN0713 Analytic 0713
Defender observes unauthorized modification or creation of Python hook files such as `.pth`, `sitecustomize.py`, or `usercustomize.py` in Python `site-packages`, `dist-packages`, or user paths. This is often correlated with subsequent unexpected interpreter execution (e.g., python3 running without user interaction), changes in interpreter behavior (e.g., malicious imports), and outbound connections initiated from Python. Defender links write/modify actions on hook files with execve of python process and/or anomalous child process or network activity.
