So you are on a Windows 8.1 box. You go to run the trusty mimikatz-->wdigest and it fails.
Well technically it will work but there wont be anything there
Using the current mimikatz that ships with metasploit (as of 1/16/2015) will not return anything. This is because 8.1 doesn't keep passwords in memory any more.
However, you should still be able to get hashes and kerberos tickets
The current standalone version of mimikatz will do this
https://github.com/gentilkiwi/mimikatz/releases/
and using the
mimikatz # sekurlsa::logonpasswords
https://github.com/gentilkiwi/mimikatz/wiki/module-~-sekurlsa
Dumping kerberos tickets should also work
mimikatz # sekurlsa::tickets /export
relevant to the above

minidump should also work

Curious what works with different versions of Windows?
