RE: [Full-Disclosure] Israeli boffins crack GSM code

["Rainer Gerhards" <rgerhards@xxxxxxxxxxxxxx>]

It was in the media over here in Germany some days ago. It seems to be a
fundamental flaw in the GSM design. AFIK, the attacker pretends to be a
GSM base station and can receive the call via a cell handover. Using
this technology, it would also possible to call "in the name of" (with
the caller id of) any victim that comes close enough to the fake base
station. It was said that the GSM providers do not really care because
a) it would be to hard to set up the equipment and b) it would probably
to expensive for the operators to fix this ;)
 
None of this is first-hand knowledge, but it may be helpful...
