NT Password Security Update. Registry values changed!
Well, I did some more research into the NT password security issue and I discovered that I can get access to the Security section of the registry and there are some VERY interesting values there, stored as raw hex. I created a test user and checked the values of these registry keys with two different passwords and iterestingly enough the data in the keys changed when I changed the password. I plan on doing some more work, including changing the values and seeing if the password change, but I've been somewhat busy lately. I've st up a web page at http://shadowland.rh.uchicago.edu/ntcrypto.html that has the password I used and the data in the two registry values that changed when I changed the password. I invite people to look at it and speculate what the change means. Also, I can provide a few more plaintext/cyphertext pairs if necessary. The change in the values could be something like update time, but I don't think that they'd store that as raw hex, espically hex as long as the stuff I got. Good luck figuring it out. _____________________________________________________________________________ Ted Cabeen cabeen@netcom.com Finger for PGP Public Key secabeen@midway.uchicago.edu "I have taken all knowledge to be my province." cococabeen@aol.com

How did you do that? The SECURITY section is always greyed out and the operating system will not allow you to change the permissions on it. If you did indeed gain access to that area then you've probably found a flaw in the tamperproof capabilities of NT. - Andy
