Microsoft’s Windows Hello fingerprint authentication has been bypassed
Microsoft’s Windows Hello fingerprint authentication has been bypassed
Windows laptop manufacturers will likely need to fix this one.
You're viewing a single thread.
This is the best summary I could come up with:
Microsoft’s Offensive Research and Security Engineering (MORSE) asked Blackwing Intelligence to evaluate the security of fingerprint sensors, and the researchers provided their findings in a presentation at Microsoft’s BlueHat conference in October.
The team identified popular fingerprint sensors from Goodix, Synaptics, and ELAN as targets for their research, with a newly-published blog post detailing the in-depth process of building a USB device that can perform a man-in-the-middle (MitM) attack.
Blackwing Intelligence researchers reverse engineered both software and hardware, and discovered cryptographic implementation flaws in a custom TLS on the Synaptics sensor.
The complicated process to bypass Windows Hello also involved decoding and reimplementing proprietary protocols.
The researchers found that Microsoft’s SDCP protection wasn’t enabled on two of the three devices they targeted.
Blackwing Intelligence now recommends that OEMs make sure SDCP is enabled and ensure the fingerprint sensor implementation is audited by a qualified expert.

... Did that say "custom implementation of TLS"?
That's like... The first rule of security. You don't roll your own cryptographic implementation. Like, first you're told that, then they tell you the difference between security and obscurity, say both those things in bold, and continue with whatever beginner topic
