Hackers deploy fileless Linux rootkit on F5 BIG-IP APM devices
- Engineer — Act: Active breach campaign targeting F5 BIG-IP APM appliances — a common enterprise edge device. Audit your BIG-IP APM fleet for indicators of compromise: look for anomalous PHP interpreter activity, unexpected in-memory web shell behavior, and verify firmware/software versions against F5’s latest advisories.
- SOC/IR — Act: The fileless, memory-resident web shell evades file-based detection, so standard endpoint scans will miss it. Hunt for anomalous PHP file-load interception and unusual outbound connections from F5 BIG-IP APM processes; if your org runs BIG-IP APM, treat as assume-breach and initiate a memory forensics sweep.
- Leader — Plan: Active compromise campaign against widely-deployed F5 BIG-IP APM appliances — confirm with your network/infra team whether your org runs these devices, verify that monitoring and patching processes are in place, and be prepared to brief leadership if exposure is confirmed.
