Researchers have found a low-cost attack method that may be used to brute-force fingerprints on cellphones in order to get beyond user authentication and take over the devices.
The BrutePrint method uses two zero-day vulnerabilities in the smartphone fingerprint authentication (SFA) framework to circumvent restrictions placed in place to stop unsuccessful biometric authentication attempts.
Cancel-After-Match-Fail (CAMF) and Match-After-Lock (MAL) vulnerabilities take use of logical deficiencies in the authentication framework that result from inadequate security of fingerprint data on the Serial Peripheral Interface (SPI) of fingerprint sensors read more New BrutePrint Attack Lets Attackers Unlock Smartphones with Fingerprint Brute-Force.
