Awesome

Features

• Core:
  • Lists open SMB pipes on the remote machine (in modes scan authenticated and fuzz authenticated)
  • Tries to connect on a list of known SMB pipes on the remote machine (in modes scan unauthenticated and fuzz unauthenticated)
  • Calls one by one all the vulnerable RPC functions to coerce the server to authenticate on an arbitrary machine.
  • Random UNC paths generation to avoid caching failed attempts (all modes)
  • Configurable delay between attempts with --delay
• Options:
  • Filter by method name with --filter-method-name, by protocol name with --filter-protocol-name or by pipe name with --filter-pipe-name (all modes)
  • Target a single machine --target or a list of targets from a file with --targets-file
  • Specify IP address OR interface to listen on for incoming authentications. (modes scan and fuzz)
• Exporting results
  • Export results in SQLite format (modes scan and fuzz)
  • Export results in JSON format (modes scan and fuzz)
  • Export results in XSLX format (modes scan and fuzz)

Installation

You can now install it from pypi (latest version is <img alt="PyPI" src="https://img.shields.io/pypi/v/coercer">) with this command:

sudo python3 -m pip install coercer

Quick start

• You want to assess the Remote Procedure Calls listening on a machine to see if they can be leveraged to coerce an authentication?

  • Use scan mode, example:

• You want to exploit the Remote Procedure Calls on a remote machine to coerce an authentication to ntlmrelay or responder?

  • Use coerce mode, example:

• You are doing research and want to fuzz Remote Procedure Calls listening on a machine with various paths?

  • Use fuzz mode, example:
