cellular snooping

Silently tapping into a private cell phone conversation is no longer a high-tech trick reserved for spies and the FBI. Thanks to the work of two young cyber-security researchers, cellular snooping may be soon be affordable enough for your next-door neighbor. In a presentation Wednesday at the Black Hat security conference in Washington, D.C., David Hulton and Steve Muller demonstrated a new technique for cracking the encryption used to prevent eavesdropping on GSM cellular signals, the type of radio frequency coding used by major cellular service providers including AT&T, Cingular and T-Mobile. Combined with a radio receiver, the pair say their technique allows an eavesdropper to record a conversation on these networks from miles away and decode it in about half an hour with just $1,000 in computer storage and processing equipment.
