Hackers Plant Covert Malware in Major Telecom Networks

A state-sponsored threat actor, CL-STA-0969, has been targeting telecommunications organizations in Southeast Asia in a sophisticated espionage campaign lasting 10 months. According to Palo Alto Networks Unit 42, the attackers focused on critical telecom infrastructure between February and November 2024. The campaign is notable for its high operational security (OPSEC) and the deployment of specialized tools like Cordscan to collect mobile device location data. While the group gained remote control over compromised networks, researchers found no evidence of data exfiltration. The actor shares significant overlaps with the China-nexus group Liminal Panda, indicating a calculated and persistent effort to maintain stealthy access to sensitive networks.
