Well, that didn't take long.
Four days after Samsung released its long-awaited Galaxy S5, security researchers say they've already found a way to hack the smartphone's fingerprint sensor.
In a video posted Tuesday on YouTube, experts from Security Research Labs demonstrated an apparent breach of the S5 using similar tactics employed late last year to bypass the fingerprint lock on Apple's(AAPL, Fortune 500) iPhone 5s.
The group says it used a camera-phone photo of a fingerprint on a smartphone screen to create a "fake finger" sheet out of a wood-glue mold. That allowed them to access the S5's home screen and even send money via the PayPal app, which uses fingerprint authentication.
"Samsung does not seem to have learned from what others have done less poorly," Security Research Labs said.
"Incorporation of fingerprint authentication into highly sensitive apps such as PayPal gives a would-be attacker an even greater incentive to learn the simple skill of fingerprint spoofing."
