Unit 42 Uncovers PEERSTITCH, a Stealthy FortiGate Implant

Unit 42 researchers discovered PEERSTITCH, a memory-resident ARM64 malware deployed through exploitation of CVE-2024-47575 against over 500 FortiGate firewalls. The implant operates stealthily within memory, leaving minimal traces on disk. Attackers leveraged the critical vulnerability to establish persistent access to network perimeters.

Why it matters: Firewall administrators must immediately patch CVE-2024-47575 (CVSS 9.8) on all FortiGate devices, as this active exploitation targets hundreds of organizations and delivers difficult-to-detect implants at critical infrastructure chokepoints.
