Protect your subscribers, services and revenues from SS7 attacks

Recent publicly presented research has shown that a number of vulnerabilities in SS7 networks is currently being exploited on a global scale for attacks on operators and individual subscribers. The weaknesses exposed open the door for advanced fraud, hijacking of subscriber communications as well as service disruption. Subscribers may be located down to street level, calls and messages tapped, subscriber profiles tampered with to use services free of charge, and in the worst case, services made completely unavailable.

All these threats rely to a large extent on insufficient filtering of SS7 messages, meaning that non-authorized SS7 nodes can request subscriber information and update subscriber profiles in situations where this is not warranted. As more independent parties such as MVNOs and micro-operators access SS7 networks, it has become easier for malicious actors to exploit this central weakness.

Symsoft SS7 Firewall is developed to protect mobile operators from attacks by tracking SS7 sessions and inspecting signaling traffic in real time. Illicit messages and patterns can be blocked immediately, ensuring that third parties are unable to access subscriber information or change subscriber profiles. A number of methods are employed to intelligently filter traffic and block specific attacks, with an intuitive GUI for simple configuration of rules.
