In this talk, we will discuss the current status, possible solutions, and outline advanced SS7 attacks and defenses using open-source SS7 firewall which we will publish after the talk. The signaling firewall is new, so we will not only use it to reduce the vulnerabilities in the SS7 networks, but we also show how to trick and abuse the attackers to make the work much harder for attackers, and give them a hard time interpreting the results. Intelligence agencies love SS7 for the wrong reasons.
