Apple's iPhone 5s was sold worldwide on the 20th. The German hacker group Computer Club Chaos (CCC) claimed on the 22nd that it had cracked the 5s fingerprint recognition and unlocking function.
CCC put a video on its own website to show how they used fake fingerprints to bypass the 5s Touch ID fingerprinting system and describe their biometric team members, how to crack this new fingerprint reader.
Two well-known iPhone security experts told Reuters that they believe CCC has successfully cracked the fingerprint recognition function, although they have not followed suit. Apple did not respond to this news. CCC said that they first took a fingerprint of an iPhone user from a glass, then transferred it onto a transparent film, and pressed it on the HOME button with a real finger to unlock the locked phone.
The CCC did not claim to obtain fingerprint information from the iPhone 5s, but instead obtained high-resolution fingerprints from elsewhere. Apple stores fingerprint information in the A7 chip. CCC said that this technique has been used to crack the vast majority of fingerprint scanners on the market. A hacker named Starbug said on the website: "Fingerprints should not be used to safeguard the security of anything. People leave fingerprints in various places and want to steal fingerprints by stealing traces. It is very simple."
