About SS7 security

SS7 (Signaling System No. 7) is a 1975 telecom protocol with fundamental trust model flaws — any interconnected entity can execute location tracking, SMS interception, and call redirection attacks

Risk assessment is based on: country regulatory environment, documented state interception capability, known incidents from public research (Positive Technologies, SRLabs, GSMA FASG, FCC reports)

This tool does not perform live SS7 queries — it provides a risk model based on publicly documented information
