Hello Mutt,
I'm deeply interested in learning the full spectrum of ss7 hacks and tricks - location,sms-intercept,"fake" cell towers,rerouting calls back to fake VLR etc. Seems you know a lot on the subject.If you or a friend can teach me the ropes in great detail about ss7 vulnerabilities,and the tools required to exploit them, I'd love to learn,and possibly hire you.
