Protect Your Network: FBI Warns of Proxy Abuse on End-of-Life Routers

May 28, 2025

Inventory, segment, and secure outdated devices using FBI IoCs to block anonymized cybercriminal traffic.

Cybercriminals are installing proxy services on end-of-life routers to anonymize illicit traffic, leading the FBI to issue a Public Service Announcement and a companion document outlining IoCs and TTPs for these unsupported devices. Organizations should inventory and replace or segment outdated routers, apply vendor patches or configuration mitigations where available, and integrate the FBI’s indicators into network monitoring to detect and block exploitation.
