Windows 7 - UAC bypass

Recommended Posts

Program, Source Code and Step-by-Step Guide

While Windows 7 was still in beta Microsoft said this was a non-issue, and ignored my offers to give them full details for several months. so there can't be an issue with making everything public now.

This works against the RTM (retail) and RC1 versions of Windows 7. It probably won't

work with the old beta build 7000 due to changes in which apps can auto-elevate.

Microsoft could block the binaries via Windows Defender (update: they now do via MSE), or plug the CRYPTBASE.DLL hole, but unless they fix the underlying code-injection / COM-elevation problem the file copy stuff will still work. Fixing only the CRYPTBASE.DLL part, or blocking a particular EXE or DLL, just means someone has to find a slightly different way to take advantage of the file copy part. Finding the CRYPTBASE.DLL method took about 10 minutes so I'd be surprised if finding an alternative took long.

Even if the hole is fixed, UAC in Windows 7 will remain unfair on third-party code and inflexible for users who wish to use third-party admin tools.
