On: SS7 MITM Attack Against WhatsApp and Telegram

[danellis]

When people perform attacks like this, how are they getting access to the SS7 network? Would they not need use of a (presumably expensive) trunk?

They are the local government and they just get access. They don't need to hack anything, they can just tell the local telco operators to give them access and that is the end of that.

You pay someone giving you access. Check the YouTube videos up there, the talk at the CCC is worth it.

Saw the talk live, can confirm it's worth watching.
