The two challenges of cracking encryption and handling frequency hopping got confused in the press. The project has so far focused on the former but we though it was necessary to show that the latter provides no protection either. > Btw Karsten: although the article on PCWorld seems one of the more > accurate, they seem to be refering to you by the name of Knoll several > times. > http://www.pcworld.com/article/185542/hackers_show_its_easy_to_snoop_on_a_gsm_call.html I love it! "Dr. Knoll" really sounds like the mad German scientist I always wanted to be ;-) Cheers to a very rewarding 26C3, -Karsten > Fabian > > On Wed, Dec 30, 2009 at 12:51 PM, Ronald <[email protected]> wrote: >> Hi guys, >> Couldn't be there at the conference.
