A researcher, who hacked the iPhone 5S Touch ID sensor a year ago, found that little progress has been made security wise with the release of iPhone 6.
Marc Rogers, principal security researcher at Lookout, revealed that the fingerprint sensor was still vulnerable to being unlocked by skillful criminals using lifted fingerprints of device owners.
While it did appear that the sensor had improved slightly – including the fact that the technology was “more sensitive” due to a higher resolution scanning part, which would require an attacker to have more expertise and a “really good copy of someone's fingerprint,” to break into the phone – Rogers was ultimately a “little disappointed that Apple didn't take this chance to really tighten up the security of Touch ID,” particularly in light of the scheduled October release of digital wallet service Apple Pay.
