"Researchers Build Firewall to Deflect SS7 Attacks"

Researchers from P1 Security have developed a firewall to combat attacks launched by the exploitation of Signaling System 7 (SS7) vulnerabilities within the mobile operators’ core networks, which will be presented at Black Hat USA. If exploited, SS7 vulnerabilities could allow cybercriminals to perform a number of malicious activities such as capture two-factor authentication codes, listen in on phone calls, manipulate the sending of text messages, and keep record of a phone’s location.  This article discusses how this firewall is expected to enhance the security of mobile core networks.
