Researcher: SIM cards vulnerable to hacking |
July 22, 2013
Millions of mobile phones may be vulnerable to spying due to the use of outdated, 1970s-era cryptography, according to new research due to be presented at the Black Hat security conference.
Karsten Nohl, an expert cryptographer with Security Research Labs, has found a way to trick mobile phones into granting access to the device’s location, SMS functions and allow changes to a person’s voicemail number.
Nohl’s research looked at a mobile phones’ SIM (Subscriber Identification Module), the small card inserted into a device that ties it to a phone number and authenticates software updates and commands sent over-the-air from an operator.
More than 7 billion SIM cards are in use worldwide. To ensure privacy and security, SIM cards use encryption when communicating with an operator, but the encryption standards use vary widely.
