Network information disclosure

SS7 Network Information Disclosure

SS7 (Signaling System No. 7) is a set of telephony signaling protocols used to set up and tear down telephone calls, manage mobile network operations, and enable advanced features like SMS and call forwarding. Information disclosure in SS7 networks occurs due to vulnerabilities in the protocol, allowing attackers to intercept calls and messages or track users’ locations.

This risk stems from the lack of strong security measures in SS7, as it was designed for a closed, trusted network. To mitigate these issues, network operators must implement security measures like intrusion detection systems and stringent access controls.
