A year later, researchers at the security firm FireEye have in fact put their finger on a rather disturbing breach. Vulnerability would allow malicious people to recover fingerprints and then reuse, unbeknownst to their owners.

If the hacker manages to have access to the Android kernel, he could then have access to the fingerprint reader and thus recover the person's fingerprint at the time of use, without having to enter the secure area where the or fingerprints. An imprint that he can then use as he pleases.

Fortunately, there is a solution. It seems that the flaw described here would only affect the Galaxy S5 running Android 4.4 KitKat. Those under Android 5.0 Lollipop would seem more safe. In short, if you haven't updated your device yet, that's one more reason.

It remains to be seen whetherother smartphones the brand could suffer from this vulnerability, like the Galaxy Note 4 and Galaxy Note Edge, which also have a fingerprint reader. Samsung is working on the issue and could offer a patch to plug the breach.
