NO FIX YET · SEE WHAT TO DO
Telecom security firm ENEA reports SilentAir, a Chinese cyber-espionage group active since at least early 2025, has backdoored telco networks in six countries, mostly Taiwan. The backdoors send malicious SS7 and Diameter signalling commands to collect device data, track subscriber locations and intercept calls and SMS; in rare cases it targeted VIPs such as political figures and government officials. ENEA links it to Liminal Panda (cooperation not confirmed). Activity described as ongoing. The affected telcos are not named, and no indicators were published in the coverage (reported via Risky Bulletin, 13 Nov 2026).
