Linux Agent Copying Itself Into Hidden Or Support Paths
Detects AI agent processes writing executable files (.sh, .py, .bin, .service) to hidden directories or common persistence staging paths, which indicates the agent is replicating itself to establish alternative execution points.
Updated Jan 10, 2025 · OCI AI Security Team
Problem Statement
Self-replication into hidden or system-like paths is how a rogue agent ensures it cannot be completely removed by simply stopping the primary process. By placing copies of itself in obscure locations, the rogue agent creates multiple points of re-execution, making full eradication require comprehensive filesystem forensics.
Sample Logs
{"timestamp":"2025-01-10T12:30:00Z","computer_name":"oci-worker-41","user":"agent_svc","image":"/usr/bin/python3","target_filename":"/home/agent_svc/.local/bin/svc_helper.py","event_type":"CreateFile"}Required Fields
False Positives
- ·Python package installers that place entry-point scripts in ~/.local/bin
- ·Legitimate agent deployment pipelines that copy agent binaries to /opt or /usr/local/bin
Tuning Guidance
Alert specifically on files written to hidden dot directories (/.local/, /.cache/) combined with executable file extensions. Writes to /opt and /usr/local/bin require root and should be correlated with sudo events.
