GSM Cracked - 26th Chaos Communications Congress

The annual Chaos Communications Congress is barely into day 2 of its 26th meeting and the folks have released published open source instructions for cracking the A5/1 mobile telephony encryption algorithm and for building an IMSI catcher that intercepts mobile phone communication. GSM, you're no longer safe!<p /><blockquote class="gmail_quote" style="border-left:1px solid rgb(204,204,204);padding-left:1ex;margin:0 0 0 .8ex;"> The Global System for Mobile Communications (GSM)
standard for digital mobile phone networks, which is used by around
four billion people in 200 countries, is quite insecure, explained
cryptography expert Karsten Nohl in front of a large audience of
hackers. While this has been known in academic circles since 1994, the
evidence now produced leaves "no more room for playing hide and seek"
said Nohl.
 Kudos.<p /></div>
