Saxophonist brings us a story from Forbes about security researchers who demonstrated a new method for breaking the encryption on GSM cellular signals. The presentation was made at the recent Black Hat conference, and it's notable for the fact that the technique only requires "about half an hour with just $1,000 in computer storage and processing equipment." The researchers also claim to have found a faster method, which they intend to market for $200,000 - $500,000. Quoting: "Undetectable, 'passive' systems like the one that Muller and Hulton have created aren't new either, though previous technologies required about a million dollars worth of hardware and used a "brute force" tactic that tried 33 million times as many passwords to decrypt a cell signal. All of that means, Hulton and Muller argue, that their cheaper technique is simply drawing needed attention to a problem that mobile carriers have long ignored--one that well-financed eavesdroppers may have been exploiting for years. 'If governments or other people with millions of dollars can listen to your conversations right now, why shouldn't your next-door neighbor?' Muller says."
