Pass-The-Hash Toolkit v1.3 is Available for Download

Use Netsparker


The Pass-The-Hash Toolkit contains utilities to manipulate the Windows Logon Sessions maintained by the LSA (Local Security Authority) component. These tools allow you to list the current logon sessions with its corresponding NTLM credentials (e.g.: users remotely logged in thru Remote Desktop/Terminal Services), and also change in runtime the current username, domain name, and NTLM hashes (YES, PASS-THE-HASH on Windows!).

Pass-The-Hash Toolkit

Pass-The-Hash Toolkit is comprised of three tools: IAM.EXE, WHOSTHERE.EXE and GENHASH.EXE.

GENHASH.EXE
This is just a utility that uses some undocumented Windows functions to generate the LM and NT hash of a password. This tool is useful to test IAM.EXE and WHOSTHERE.EXE and perhaps to do some other things. Pretty simple and small tool.

IAM.EXE
This tools allows you to change your current NTLM credentials without having the cleartext password but the hashes of the password. The program receives a username, domain name and the LM and NT hashes of the password; using this it will change in memory the NTLM credentials associated with the current windows logon session. After the program performs this operation, all outbound network connections to services that use for authentication the NTLM credentials of the currently logged on user will utilize the credentials modified by IAM.EXE.

WHOSTHERE.EXE
This tools will list logon sessions with NTLM credentials (username,domain name, LM and NT hashes). Logon sessions are created by windows services that log in using specific users, remote desktop connections, etc. This tool has many uses, one that i think is interesting: Let’s say you compromised a Windows Server that is part of a Windows Domain (e.g.: Backup server) but is NOT the domain controller.
