Tapping into Mobile Phones?

There was a hack last year talked about at defcon using radio to create a spoof gsm tower and then because the attacker was the tower they could disable encryption.

Edit: Yeah the above post was the guy, his talk is on youtube.
 
Mobile phone remote hacking has been around for years. In recent years with smart phones it has become more active. Did you see the recent lecture at 28c3 ?


There is also the existence of software and hardware package, that can be rented, that can intercept peoples phone calls and various other features but that is regulated by the government so only they can use it.

When I worked in Sky, we had multiple letters from a guy claiming similar from Sky dishes and he wanted all of them in the UK taken down. It also from time to time include diagrams on how it worked.

Guy was a loonly, so is this guy.

Is a loonly a lonely lunatic? :D

I would say it's nonsense, those graphics cards don't have the power to do it. It's not a question of software, it's the fact that there is not a single piece of hardware has the power to do it in that timeframe.
Lots of things on the internet are made up.

What I do know is, the method he'd come up with did not require the use of rainbow tables, etc. so completely different ballgame - it was far more elegant than a brute force attack.


EDIT: just found some of the old logs, don't really understand it but its something to do with factorising the modulus of a 1024bit RSA key he'd found a method with GPU based computing that was several orders of magnitude more efficent than previous methods.

Well GCHQ wouldn’t be taking notice of your loony customer and if they were it wouldn’t be from his caravan park.
 
It used to be much easier in the analogue era. It can still be done with gsm/pcn phones, all depends on his hardware hacking skills. Very easy to modify a certain old motorola gsm handset hooked upto a pc and decrypt traffic coming of a cell tower in realtime :)
 
Either by cell tower spoofing, or the fact that GSM's A5/1 encryption has been broken you could listen to people's calls (both very illegal). But it's a passive thing so you wouldn't hear "a bit of static on the line" like you might with tapping a physical analogue line.
