However, based on preliminary testing, CyberArk researchers believe that mitigation measures limit the attack area, but rely on users with specific cameras.
“The implicit trust in the input from the peripherals that is inherent in the system design remains. To more comprehensively mitigate this inherent trust problem, the host must prioritize its biometric device before trusting it. We need to verify the integrity, “says Tsarfati.
