After a mere ten years, someone has finally modernized this concept into a much more potent attack. Core Security has released Pass-The-Hash Toolkit, which runs on Windows and works with NTLM hashes. It's comprised of two key modules:
- IAM.EXE - This tool "injects" another user's NTLM credentials into your current Windows logon session, given their username, Windows domain, and NTLM hash. You can then use the 'net' tools or any other Windows software that authenticates via NTLM, all under the assumed privileges of the compromised user account.
- WHOSTHERE.EXE - Lists the usernames and NTLM hashes of all users logged on to a system.
