Windows Hello Fingerprint Authentication Vulnerabilities Exposed

Security researchers have discovered vulnerabilities in the top three fingerprint sensors used in Dell, Lenovo, and Microsoft laptops, allowing them to bypass Windows Hello's fingerprint authentication. The researchers were able to build a USB device capable of deploying a man-in-the-middle attack, granting unauthorized access to stolen or unattended devices. The vulnerabilities were found in Goodix, Synaptics, and ELAN fingerprint sensors. Microsoft's SDCP protection was not enabled, making the bypass possible. Users are advised to enable SDCP protection as a precautionary measure.
