Serious SIM Card Security Flaw Affects Millions of Mobile Phones

Via: Cnet:

A vulnerability on SIM cards used in some mobile phones could allow malware infection and surveillance, a security researcher warns.
Karsten Nohl, founder of Security Research Labs in Berlin, told The New York Times that he has identified a flaw in SIM encryption technology that could allow an attacker to obtain a SIM card’s digital key, the 56-digit sequence that allows modification of the card. The flaw, which may affect as many as 750 million mobile phones, could allow eavesdropping on phone conversations, fraudulent purchases, or impersonation of the handset’s owner, Nohl warned.
