German Group Says It Hacked Apple iPhone Fingerprint Scanner
A group of German hackers claimed to have cracked the iPhone fingerprint scanner.
Two iPhone security experts told Reuters that they believed the German group, known as the Chaos Computing Club, or CCC, had succeeded in defeating Apple's Touch ID, though they had not personally replicated the work.
CCC, one the world's largest and most respected hacking groups, posted a video on its website that appeared to show somebody accessing an iPhone 5S with a fabricated print, said Reuters. The site described how members of its biometrics team had cracked the new fingerprint reader, one of the few major high-tech features added to the latest version of the iPhone.
The group said they targeted Touch ID to knock down reports about its "marvels," which suggested it would be difficult to crack, Reuters said.
The group said it defeated Touch ID by photographing the fingerprint of an iPhone's user, then printing it on to a transparent sheet, which it used to create a mold for a "fake finger."
CCC said similar processes have been used to crack "the vast majority" of fingerprint sensors on the market.
Touch ID, which was only introduced on the top-of-the-line iPhone 5S, lets users unlock their devices or make purchases on iTunes by simply pressing their finger on the home button. It uses a sapphire crystal sensor embedded in the button.
Data used for verification is encrypted and stored in a secure enclave of the phone's A7 processor chip.
