Unlike passwords, fingerprints last a lifetime and are usually associated with critical identities. Thus, the leakage of fingerprints is irredeemable. It will be even a disaster if the attackers can remotely harvest fingerprints in a large scale.
In this talk, we will reveal some severe issues with the current Android fingerprint frameworks that have long been neglected by vendors and users. We will provide in-depth security analysis of the popular mobile fingerprint authentication/authorization frameworks, and discuss the security problems of existing designs, including (1) the confused authorization attack that enables malware to bypass pay authorizations protected by fingerprints, (2) TrustZone design flaws and fingerprint sensor spying attack to harvest fingerprints, (3) pre-embedded fingerprint backdoors, etc. We will show live demos, such as hijacking mobile payment protected by fingerprints, and collecting fingerprints from popular mobile devices. We will also provide suggestions for vendors and users to better secure the fingerprints.
