GSM Phones Vulnerable to Hijack Scams

Researchers say that a vulnerability in the GSM technology could allow hackers to hijack your phone and run up your bill. Either that, or researchers are just blaming hackers for all those sex-chat calls they made last month. They could use the vulnerability in the GSM technology -- which is used by most telecom operators globally and by billions of people -- to make calls or send texts to expensive, premium phone and messaging services in scams, said Karsten Nohl, head of Berlin-based Security Research Labs.
