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:

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!

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)
    • 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.
