[...] When we last spoke with Cellcrypt, they told us about a group of white hat hackers in Germany who we…. The group is led by Karsten Nohl, and yesterday news broke that his team have cracked the GSM algorithm, technically known as the A5/1 privacy algorithm. The algorithm is used to tell your voice call to hop frequencies, thus encrypting your call. Each mobile device is given a key, which decodes the hopping algorithm so you can listen to a call. The GSM association has been quoted saying that “by simply modifying the existing algorithm, [carriers] could thwart any unintended surveillance.” This statement doesn’t ring entirely true.
