Hackers linked to a group called SilentAir intercept calls and SMS messages by gaining access to equipment inside mobile telecom networks, according to research published by Enea. The activity focuses primarily on Taiwanese subscribers, with the group using compromised mobile network nodes to route or capture communications.
Enea says it found attack sources across multiple Asian countries and attributes the behavior to a state-level capability, describing a high-confidence assessment. Coverage across outlets emphasizes how the intrusion is positioned “inside” telecom infrastructure, enabling collection of both voice communications and text content. One outlet also mentions a connection between SilentAir and another naming convention used for related malicious activity.
Overall, the reporting agrees on the core claim: SilentAir operates through hacked telecom systems to spy on selected users, mostly in Taiwan. The differences are mainly in how much scope and attribution detail each outlet highlights, and whether it links SilentAir to another threat label.
