SYSKEY A utility that {encrpyts} the hashed password information in a SAM database using a 128-bit {encryption key}. SYSKEY was an optional feature added in Windows NT 4.0 SP3. It was meant to protect against off-line password cracking attacks so that the SAM database would still be secure even if someone had a copy of it. However, in December 1999, a security team from {BindView (http://bindview.com/)} found a security hole in SYSKEY which indicates that a certain form of {cryptoanalytic} attack is possible offline. A brute-force attack then appeared to be possible. Microsoft later collaborated with BindView to issue a fix (dubbed the 'Syskey Bug') which appears to have been settled and SYSKEY pronounced secure enough to resist brute-force attack. According to Todd Sabin of the BindView team RAZOR, the pre-RC3 versions of Windows 2000 were also affected. {BindView Security Advisory (http://packetstorm.securify.com/
