Users can keep thieves from stealing encrypted data by changing some settings in Windows, a Microsoft Corp. product manager said as he downplayed the threat posed by new research that shows how attackers can inspect a "ghost" of computer memory.
Russ Humphries, a senior product manager for Windows Vista security, reacted Friday to reports last week about a new low-tech technique that could be used to lift the encryption key used by Vista's BitLocker or Mac OS X's FileVault. Once an attacker has the key, of course, he could easily access the data locked away on an encrypted drive.
