There’s a lot that’s new in Apple’s just-released iPhone 6, but one feature hasn’t changed: Faked fingerprints can still fool the Touch ID fingerprint sensor. Security on the Touch ID fingerprint reader has been tightened, but only marginally, said Marc Rogers, chief security researcher at Lookout Mobile Security. “I don’t think people need to worry just yet, but there are distinct flaws that could lead to problems down the line,” he told CNET. Rogers wrote in a blog post that he was able to use the same low-budget technique to fake fingerprints and unlock the iPhone 6 as he did when he became one of the first researchers in 2013 to hack Touch ID on the iPhone 5S. “Sadly there has been little in the way of measurable improvement in the sensor between these two devices,” he wrote. “Fake fingerprints created using my previous technique were able to readily fool both devices.”
