정교한 두 개의 통신 감시 캠페인 조사로 드러남

Citizen Lab's investigation reveals two sophisticated surveillance campaigns exploiting fundamental vulnerabilities in global telecom infrastructure through SS7 and Diameter protocols. These attacks demonstrate that well-resourced adversaries can impersonate legitimate telecom operators to track mobile device locations and manipulate SIM cards, exposing critical security gaps affecting millions worldwide. The discovery represents only a fraction of ongoing exploitation, underscoring urgent need for telecom operators to implement stronger authentication and encryption mechanisms across their networks.
