Today the New York Times reported that Karsten Nohl had finally broken the A5/1 encryption algorithm used to protect GSM voice (and data) communication. He presented the details of his attack at the Chaos Communication Congress (which he pre-announced at Hacking At Random earlier this year).
Is this any news?
