GPRS-Verbindungen abhörbar

Wie die New York Times berichtet hat Karsten Nohl einen Weg gefunden den GPRS-Datenverkehr im Umkreis von bis zu 5 Kilometer zu belauschen.

A German computer engineer said Tuesday that he had deciphered the code used to encrypt most of the world’s mobile Internet traffic and that he planned to publish a guide to prompt global operators to improve their safeguards. (…) In Germany, Mr. Nohl said he was able to decrypt and read data transmissions on all four mobile networks — T-Mobile, O2 Germany, Vodafone and E-Plus. He described the level of encryption provided by operators as “weak.”
