Microsoft updated its guidance on Bitlocker countermeasures in response to the F-Secure’s findings.But for Mac computers without the latest T2 chip, Apple recommended users to set a firmware password in order to help harden the security of their computers.

Intel has yet to comment on the matter.

According to the researchers there’s no reliable way to “prevent or block the cold boot attack once an attacker with the right know-how gets their hands on a laptop,” but suggest the companies can configure their devices so that attackers using cold boot attacks won’t find anything fruitful to steal.

Meanwhile, they recommend the IT departments to configure all company computers to either shut down or hibernate (not enter sleep mode) and require users to enter their BitLocker PIN whenever they power up or restore their PCs.

Attackers could still perform a successful cold boot attack against computers configured like this, but since the encryption keys are not stored in the memory when a machine hibernates or shuts down, there will be no valuable information for an attacker to steal.
