SIM Card Hack Allows Attackers to Remotely Control Victim's Phone

A dangerous SIM card hack has been discovered, potentially allowing attackers to remotely send premium SMS messages or re-direct and record calls, Forbes reports

It took Karsten Nohl, German cryptographer and security researcher who discovered the flaw, three years of research and nearly 1,000 SIM cards to find and test the hack, which is based on an old encryption standard — DES (Digital Encryption Standard).

Not all SIM cards are vulnerable — just under a quarter of the SIM cards tested were susceptible to the hack — but those that are can be hacked via sending a hidden SMS. All in all, millions of phones worldwide could be affected
