Microsoft Gave FBI a Set of BitLocker Encryption Keys To Unlock Suspects' Laptops

An anonymous reader quotes a report from TechCrunch: Microsoft provided the FBI with the recovery keys to unlock encrypted data on the hard drives of three laptops as part of a federal investigation, Forbes reported on Friday. Many modern Windows computers rely on full-disk encryption, called BitLocker, which is enabled by default. This type of technology should prevent anyone except the device owner from accessing the data if the computer is locked and powered off. But, by default, BitLocker recovery keys are uploaded to Microsoft's cloud, allowing the tech giant -- and by extension law enforcement -- to access them and use them to decrypt drives encrypted with BitLocker, as with the case reported by Forbes. The case involved several people suspected of fraud related to the Pandemic Unemployment Assistance program in Guam, a U.S. island in the Pacific. Local news outlet Pacific Daily News covered the case last year, reporting that a warrant had been served to Microsoft in relation to the suspects' hard drives. Kandit News, another local Guam news outlet, also reported in October that the FBI requested the warrant six months after seizing the three laptops encrypted with BitLocker. [...] Microsoft told Forbes that the company sometimes provides BitLocker recovery keys to authorities, having received an average of 20 such requests per year.
