Defending, monitoring & detecting exploits on my telecom network

Nowadays, operators are handling daily frauds, signaling attacks on 2G,3G and 4G networks, with a special mention to attackers starting frauds on Friday night, thank you guys!

Since several years now I always have been on the offensive side regarding telecom core networks signalisation, that’s why I started to try to catch the Friday night bad guys. During this talk I will share my experience on building monitoring solutions in an ISP playground and how you can to it by yourself with everything you already have on your network. I will also share the different interesting fraud cases and 0days I have been catching during this years and how we are handling it in my ISP.
