   CRACKED Thought your new digital cell phone was safe from high-tech
   thieves? Guess again. Silicon Valley cypherpunks have broken the
   proprietary encryption technology used in 80 million GSM (Global
   System for Mobile communications) phones nationwide, including
   Motorola MicroTAC, Ericsson GSM 900 and Siemens D1900 models. Now
   crooks scanning the airwaves can remotely tap into a call and
   duplicate the owner's digital ID. "We can clone the phones," brags
   Marc Briceno, who organized the cracking. His advice: manufacturers
   should stick to publicly vetted codes that a bunch of geeks can't
   crack in their spare time. --By Declan McCullagh/Washington

God. There is nothing I hate more than crappy journalism. Mr McCullagh is
wrong. "Crooks" cannot scan the airwaves and remotely tap into a call via
the methods described by the Smartcard Association people. What they can do
is clone the smart card (SIM) inside a GSM phone in several hours if they
obtain physical access to the device.
