Windows Credentials Editor (WCE) is a security tool that allows to list Windows logon sessions and add, change, list and delete associated credentials (e.g.: LM/NT hashes, Kerberos tickets and cleartext passwords).

The tool allows users to:

• Perform Pass-the-Hash on Windows
• 'Steal' NTLM credentials from memory (with and without code injection)
• 'Steal' Kerberos Tickets from Windows machines
• Use the 'stolen' kerberos Tickets on other Windows or Unix machines to gain access to systems and services
• Dump cleartext passwords stored by Windows authentication packages

WCE is a security tool widely used by security professionals to assess the security of Windows networks via Penetration Testing.

For example:
C:\Users\test>wce.exe

How to Change my current NTLM credentials?

wce.exe -s <username>:<domain>:<lmhash>:<nthash>
For example:
C:\Users\test>wce.exe -s testuser:amplialabs:01FC5A6BE7BC6929AAD3B435B51404EE:0CB6948805F797BF2A82807973B89537
