Fingerprint | Breaking Cybersecurity News | The Hacker News

Researchers have discovered an inexpensive attack technique that could be leveraged to brute-force fingerprints on smartphones to bypass user authentication and seize control of the devices. The approach, dubbed  BrutePrint , bypasses limits put in place to counter failed biometric authentication attempts by weaponizing two zero-day vulnerabilities in the smartphone fingerprint authentication (SFA) framework. The flaws, Cancel-After-Match-Fail (CAMF) and Match-After-Lock (MAL), leverage logical defects in the authentication framework, which arises due to insufficient protection of fingerprint data on the Serial Peripheral Interface (SPI) of fingerprint sensors. The result is a "hardware approach to do man-in-the-middle (MitM) attacks for fingerprint image hijacking," researchers Yu Chen and Yiling He  said  in a research paper. "BrutePrint acts as a middleman between fingerprint sensor and  TEE  [Trusted Execution Environment]." The goal, at its core, is to...

A new research undertaken by a group of academics from the University of California San Diego has revealed for the first time that Bluetooth signals can be fingerprinted to track smartphones (and therefore, individuals). The identification, at its core, hinges on imperfections in the Bluetooth chipset hardware introduced during the manufacturing process, resulting in a "unique physical-layer fingerprint." "To perform a physical-layer fingerprinting attack, the attacker must be equipped with a Software Defined Radio sniffer: a radio receiver capable of recording raw IQ radio signals," the researchers  said  in a  new paper   titled  "Evaluating Physical-Layer BLE Location Tracking Attacks on Mobile Devices." The  attack  is made possible due to the ubiquitous nature of Bluetooth Low Energy (BLE) beacons that are continuously transmitted by modern devices to enable crucial functions such as  contact tracing  during public health emergencie...
