They don't say if it was an Apple or Android device. Either way -- that was fast. I wonder what happened here? Did the suspect not have encryption turned on? Using an older phone with known vulnerabilities? Is the FBI sitting on some 0-days?
There’s an option on iPhone’s FaceID to require eyes open and looking at phone to unlock, but this might have been deselected. Or it could be subverted.
Would be interesting if they had tech that could fool it based on known photos.
