Android full disk encryption can be brute-forced on Qualcomm-based devices

Attackers can exploit vulnerabilities in Android devices with Qualcomm chipsets in order to extract the encrypted keys that protect users' data and run brute-force attacks against them.The attack was demonstrated last week by security researcher Gal Beniamini and uses two vulnerabilities patched this year in Qualcomm's implementation of the ARM CPU TrustZone.The ARM TrustZone is a hardware security module that runs its own kernel and Trusted Execution Environment independent of the main OS.
