Re: [Brmlab] Finding TMSI

I think it's leaked during initial registration to BTS. I'm not sure with handover, though.

There were active correlation attack if you know the phone number associated with the IMSI, you send silent SMS or silent call and repeat several times. The phone is paged and you see the TMSI.
