Extremetech reports that a MITM attack was conducted against all 4G and CDMA transmissions in and around the DEFCON venue in Las Vegas. Apparently the MITM attack allowed attackers to obtain full access to some Android and PC devices, and was able to monitor data and telephony sessions.
The Register is also reporting that Security Research Labs has developed a way to monitor GPRS conversations by exploiting weaknesses in the protocol. Demonstration software is expected to be released at CCC 2011. (In 2009 SRL’s Chief Scientist also coordinated release of a rainbow table to assist in cracking GSM, and in 2010 other cryptographers where able to defeat 3G encryption).
Fun times!
