Karsten Nohl to demo data #decryption on #GPRS networks

Researcher Karsten Nohl is continuing his crusade to get mobile operators to improve the security of their networks by releasing software that can turn phones into mobile data snoops of GPRS (General Packet Radio Service) traffic.
Using a GPRS interceptor, someone could "read their neighbor's Facebook updates," he told CNET in a brief interview last week. He planned to release the software during a presentation today at the Chaos Communication Camp 2011 in Finowfurt, Germany, near Berlin.

Karsten of Security Research Labs in Berlin and a co-researcher Luca Melette were able to intercept and decrypt data sent over mobile networks using GPRS using a cheap Motorola that they modified and some free applications, according to The New York Times. They were able to read data sent on T-Mobile, O2 Germany, Vodafone, and E-Plus in Germany because of weak encryption used, and they found that Telecom Italia's TIM and Wind did not encrypt data at all, while Vodafone Italia used weak encryption, according to the report.
