Fire Ant campaign targets Cisco routers and TACACS servers
Image: Primary Incident-response firm Sygnia reported that the China-nexus actor it tracks as Fire Ant expanded a campaign to Cisco IOS XR routers, TACACS servers and Linux management hosts. Sygnia said compromised routers captured traffic, harvested credentials and suppressed logs and telemetry. The firm found a TACACS credential-collection toolset and router implants designed to hide tunnel configuration. It assessed strong overlap with UNC3886 reporting but did not make a conclusive attribution.
