Pass the Hash has many variants, from Pass the Ticket to OverPass the Hash (aka pass the key).

Hashing a password into a hash is like putting a steak through a meat grinder to make ground beef – the ground beef can never be put together to be the same steak again.

One of the biggest security concerns with Windows today is “Pass the Hash.” Simply stated, Windows performs a one-way hash function on the user’s password and the result is referred to as a “hash.” The one-way hash algorithm changes the password in expected ways given the input data (the password) with the result being scrambled data that can’t be reverted back to the original input data, the password.

This allows you to do things such as dump credentials without ever writing the mimikatz binary to disk.” Mimikatz functionality supported by Invoke-Mimikatz is noted below.īenjamin Delpy posted an Excel chart on OneDrive (shown below) that shows what type of credential data is available in memory (LSASS), including on Windows 8.1 and Windows 2012 R2 which have enhanced protection mechanisms reducing the amount and type of credentials kept in memory. The majority of Mimikatz functionality is available in PowerSploit (PowerShell Post-Exploitation Framework) through the “ Invoke-Mimikatz” PowerShell script which “leverages Mimikatz 2.0 and Invoke-ReflectivePEInjection to reflectively load Mimikatz completely in memory. While you can prevent a Windows computer from creating the LM hash in the local computer SAM database (and the AD database), though this doesn’t prevent the system from generating the LM hash in memory. The credential data may include NTLM password hashes, LM password hashes (if the password is <15 characters), and even clear-text passwords (to support WDigest and SSP authentication among others.

This is meant to facilitate single sign-on (SSO) ensuring a user isn’t prompted each time resource access is requested. Mimikatz requires administrator or SYSTEM and often debug rights in order to perform certain actions and interact with the LSASS process (depending on the action requested).Īfter a user logs on, a variety of credentials are generated and stored in the Local Security Authority Subsystem Service, LSASS, process in memory. There are two optional components that provide additional features, mimidrv (driver to interact with the Windows kernal) and mimilib (AppLocker bypass, Auth package/SSP, password filter, and sekurlsa for WinDBG). Mimikatz is a Windows x32/圆4 program coded in C by Benjamin Delpy in 2007 to learn more about Windows credentials (and as a Proof of Concept).

The Mimikatz GitHub repository is in English and includes useful information on command usage. Since the author of Mimikatz, Benjamin Delpy, is French most of the resources describing Mimikatz usage is in French, at least on his blog.

In fact I consider Mimikatz to be the “swiss army knife” of Windows credentials – that one tool that can do everything. Mimikatz is the latest, and one of the best, tool to gather credential data from Windows systems. While this page will remain, the majority of the Mimikatz information in this page is now in the “ Unofficial Mimikatz Guide & Command Reference” which will be updated on a regular basis.
