The duo says 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. Microsoft updated its guidance on Bitlocker countermeasures in response to the F-Secure's findings, while Apple said that its Mac devices equipped with an Apple T2 Chip contain security measures designed to protect its users against this attack.īut 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. The two researchers, who will present their findings today at a security conference, say they have already shared their findings with Microsoft, Intel, and Apple, and helped them explore possible mitigation strategies. According to Olle and his colleague Pasi Saarinen, their new attack technique is believed to be effective against nearly all modern computers and even Apple Macs and can't be patched easily and quickly.
