GSM has been Cracked

Good thing I belong to Verizon Wireless.

How would the attacker get hold of 2 known plain text messages needed to crack the encryption key? Text you and hope you reply with a preformed message?

An example are "SYSTEM INFORMATION 5/6/5ter" in the SACCH or "LAPDM U, func=UI" frames. Also keep in mind that there could be wrong bits in a burst due to distortion. 
And here I've been proceeding all these years under the impression that my texts and voice communications were already compromised by the federal government. Oh well, no loss.
Every cell phone tower in the Netherlands has been prepared for listening in on phone conversations by the AIVD. Before 2001, the Netherlands had the largest absolute number of wiretaps in the world. I was always under the impression the same was possible with text messages to be honest.

The cracking of GSM “encryption” has been making the inter-rounds lately, and this week on the Security Now! Podcast, Steve Gibson takes a look at how badly it’s broken, and what the potential risks are. In simple terms, it means what you say on your iPhone — or any GSM phone, which includes all phones on AT&T, T-Mobile, Rogers, and almost all phones internationally — can be intercepted, decrypted, and listened to if a person has several thousand dollars worth of equipment and the motivation to do it.

Great. We better start passing notes to each other again like we did in grade school. Then burn the evidence.
