SS7 and Diameter Attacks: How Signaling Flaws Expose Your Phone
SS7 and Diameter signaling protocols contain design flaws that enable attackers to track phone locations, intercept calls and SMS messages, and impersonate subscribers by exploiting trust relationships between telecommunications networks. These attacks do not require compromising the target device itself. A mobile security service provider outlines how such attacks work and presents defensive measures.
Why it matters: Telecom subscribers and organizations relying on SMS-based multifactor authentication (MFA) or phone-based identity verification face exposure to location tracking, call interception, and account compromise through signaling protocol weaknesses that operators control, not end users.
