mimikatz

mimikatz is a tool I've made to learn C and make somes experiments with Windows security.

It's now well known to extract plaintexts passwords, hash, PIN code and kerberos tickets from memory. mimikatz can also perform pass-the-hash, pass-the-ticket or build Golden tickets.

Build

mimikatz is in the form of a Visual Studio Solution and a WinDDK driver (optional for main operations), so prerequisites are:

• for mimikatz and mimilib : Visual Studio 2010, 2012 or 2013 for Desktop (2013 Express for Desktop is free and supports x86 & x64 - http://www.microsoft.com/download/details.aspx?id=44914)
• for mimikatz driver, mimilove (and ddk2003 platform) : Windows Driver Kit 7.1 (WinDDK) - http://www.microsoft.com/download/details.aspx?id=11800

mimikatz uses SVN for source control, but is now available with GIT too! You can use any tools you want to sync, even incorporated GIT in Visual Studio 2013 =)

Synchronize!

• GIT URL is : https://github.com/gentilkiwi/mimikatz.git
• SVN URL is : https://github.com/gentilkiwi/mimikatz/trunk
• ZIP file is : https://github.com/gentilkiwi/mimikatz/archive/master.zip

Build the solution

• After opening the solution, Build / Build Solution (you can change architecture)
• mimikatz is now built and ready to be used! (Win32 / x64 even ARM64 if you're lucky)
  • you can have error MSB3073 about _build_.cmd and mimidrv, it's because the driver cannot be build without Windows Driver Kit 7.1 (WinDDK), but mimikatz and mimilib are OK.

ddk2003

With this optional MSBuild platform, you can use the WinDDK build tools, and the default msvcrt runtime (smaller binaries, no dependencies)

For this optional platform, Windows Driver Kit 7.1 (WinDDK) - http://www.microsoft.com/download/details.aspx?id=11800 and Visual Studio 2010 are mandatory, even if you plan to use Visual Studio 2012 or 2013 after.
