mimiRust @ ?

Choose one of the following options:

  passwords:
          • dump-credentials             Dumps systems credentials through Wdigest.
          • dump-hashes                  Dumps systems NTLM hashes (requires SYSTEM permissions).
          • clear                        Clears the screen of any past output.
          • exit                         Moves to top level menu

  pivioting:
          • shell         Execute a shell command through cmd, returns output.
          • clear                        Clears the screen of any past output.
          • exit                         Moves to top level menu
          • (W.I.P)psexec                Executes a service on another system.
          • (W.I.P)pth                   Pass-the-Hash to run a command on another system.
          • (W.I.P)golden-ticket         Creates a golden ticket for a user account with the domain.

  privilege:
          • spawn-path       Spawn program with SYSTEM permissions from location.
          • clear                        Clears the screen of any past output.
          • exit                         Moves to top level menu

mimiRust @ passwords
mimiRust::passwords @ dump-credentials

MimiRust is a post-exploitation tool that can be used within redteam operations. Like the name suggests the entire project is made within the Rust language. MimiRust is capable of the following actions:

Spawning any process as SYSTEM
Executing shell commands
Extracting Windows passwords out of memory through the wdigest attack vector.
Extracting Windows NTLM hashes from user accounts (aes / des) & (md5 / rc4)

Todo:

PSExec to create service on another endpoint.
PtH (Pass-The-Hash)
Kerberos Golden Ticket

Maybe in the future I will make it polymorphic and obfuscate the strings (also polymorphic) and API calls.

Quick usage:

MimiRust can be ran in two different ways: from the command line using mimiRust.exe --help or in the shell by running the executable without any command line arguments. For help with the program type one of the following into mimiRust:

mimiRust # ?
mimiRust # h
mimiRust # help

You will now be required to type in the module that you want to access, current modules are:

passwords
pivioting
privilege

Dumping credentials from memory through wdigest

mimiRust::passwords # dump-credentials
mimiRust.exe --dump-credentials

Dumping NTLM hashes from user accounts

mimiRust::passwords @ dump-hashes
mimiRust.exe --dump-hashes

Executing shell commands

mimiRust::pivioting $ shell whoami

Spawning a process with SYSTEM

mimiRust::privilege # spawn-path cmd.exe
mimiRust.exe -s cmd.exe

Why was MimiRust made

MimiRust was created as a project by a first years Cyber Security Bachelors student. The reason for this is because I was too bored learning about business processes in a Security Bachelors that I decided to just start for myself.
