Major cellular network security flaw
Flaws in a signalling protocol used by telephone networks worldwide allow attackers to track mobile devices and intercept calls and SMS messages — all without compromising or infecting the target phone.
The security vulnerabilities are in Signalling System 7 (SS7), a standard developed in the 1970s for traditional telephone networks to manage call set-up, management, and teardown.
