According to Bleeping Computer, flaws in the SS7 and Diameter signaling protocols can allow attackers to track phone locations, intercept calls and SMS verification codes, and impersonate subscribers without needing to compromise the subscriber’s device. The explanation highlights how these attacks exploit trust relationships between telecommunications networks. Cape describes a security‑focused mobile service that defends against such signaling weaknesses.
These protocol vulnerabilities permit observers to monitor where a phone is used, capture voice calls in transit, and read short message service codes sent for verification purposes. Attackers can also assume the identity of legitimate subscribers by leveraging the flawed trust mechanisms built into SS7 and Diameter without altering or accessing the subscriber’s handset.
Cape’s approach emphasizes network‑level validation and tighter coordination between signaling elements to reduce reliance on default trust assumptions. The service aims to block unauthorized location queries, prevent interception of media flows, and enforce stronger identity verification for subscribers interacting with mobile operators.
