Windows + Dell fingerprint reader security


Recommended Posts

I almost wish I hadn't read this article:




Security researchers Jesse D'Aguanno and Timo Teräs write that, with varying degrees of reverse-engineering and using some external hardware, they were able to fool the Goodix fingerprint sensor in a Dell Inspiron 15, the Synaptic sensor in a Lenovo ThinkPad T14, and the ELAN sensor in one of Microsoft's own Surface Pro Type Covers. ...

Each fingerprint sensor was ultimately defeated by a different weakness. The Dell laptop's Goodix fingerprint sensor implemented SDCP properly in Windows but used no such protections in Linux. Connecting the fingerprint sensor to a Raspberry Pi 4, the team was able to exploit the Linux support plus "poor code quality" to enroll a new fingerprint that would allow entry into a Windows account.

Is there a way Dell or Microsoft can fix this with software or a firmware update?
