Secret mobile phone code cracked

Computer hackers this week said they had cracked and published the secret code that protects 80 per cent of the world’s mobile phones. The move will leave more than 3bn people vulnerable to having their calls intercepted, and could force mobile phone operators into a costly upgrade of their networks. Karsten Nohl, a German encryption expert, said he had organised the hack to demonstrate the weaknesses of the security measures protecting the global system for mobile communication (GSM) and to push mobile operators to improve their systems. “This shows that existing GSM security is inadequate,” Mr Nohl told an audience of about 600 people at the Chaos Communication Congress in Berlin, a four-day conference of computer hackers. “We have given up hope that network operators will move to improve security on their own, but we are hoping that with this added attention, there will be increased demand from customers for them to do this,” he told the Financial Times. “This vulnerability should have been fixed 15 years ago.
