Galaxy S5: Fingerprint reader hacked with simple trick

After Apple launched the first fingerprint reader embedded in its iPhone 5S, much discussion was made about the real usefulness of the feature and whether it would represent an increase in security. The main problem with biometric sensors such as digital printwhereas while they may in theory add an extra layer of protection, they are not mature enough and often have flaws bass of security.

Following the example of the iPhone, it was first HTC One Max that decided to implement the feature, followed by the Galaxy S5. It uses a fingerprint reader built into the home button and is apparently simple to hack using a captured fingerprint.

The SRLabs video below shows how a fake fingerprint can be used to gain unauthorized access to the Galaxy S5 using a registered fingerprint mark on the device. Once the attacker gets access, in addition to accessing the device data he can also use the fake fingerprint to initiate Paypal operations, which uses the device reader in his application. In a hypothetical situation, if the device is stolen by someone with knowledge of the failure, he will have free access to the device data if the fingerprint method is the only configured security barrier.

Despite being a relatively low risk, do you still feel safe using the Galaxy S5 fingerprint reader (or other devices with the feature)? Leave your comments below!
