Coercer - A Python Script To Automatically Coerce A Windows Server To Authenticate On An Arbitrary Machine Through 9 Methods


A python script to automatically coerce a Windows server to authenticate on an arbitrary machine through 9 methods.

Features

  • Automatically detects open SMB pipes on the remote machine.
  • Calls one by one all the vulnerable RPC functions to coerce the server to authenticate on an arbitrary machine.
  • Analyze mode with --analyze, which only lists the vulnerable protocols and functions listening, without performing a coerced authentication.
  • Perform coerce attack on a list of targets from a file with --targets-file
  • Coerce to a WebDAV target with --webdav-host and --webdav-port

Usage

$ ./Coercer.py -h                                                                                                         ______                                    / ____/___  ___  _____________  _____     / /   / __ \/ _ \/ ___/ ___/ _ \/ ___/    / /___/ /_/ /  __/ /  / /__/  __/ /      v1.6    \____/\____/\___/_/   \___/\___/_/       by @podalirius_usage: Coercer.py [-h] [-u USERNAME] [-p PASSWORD] [-d DOMAIN] [--hashes [LMHASH]:NTHASH] [--no-pass] [-v] [-a] [-k] [--dc-ip ip address] [-l LISTENER] [-wh WEBDAV_HOST] [-wp WEBDAV_PORT]                  (-t TARGET | -f TARGETS_FILE) [--target-ip ip address]Automatic windows authentication coercer over various RPC calls.options:  -h, --help            show this help message and exit  -u USERNAME, --username USERNAME                        Username to authenticate to the endpoint.  -p PASSWORD, --password PASSWORD                        Password to authenticate to the endpoint.

If omitted it will use whatever was specified as target. This is useful when target is the NetBIOS name or Kerberos name and you cannot resolve it  -l LISTENER, --listener LISTENER                        IP address or hostname of the listener machine  -wh WEBDAV_HOST, --webdav-host WEBDAV_HOST                        WebDAV IP of the server to authenticate to.  -wp WEBDAV_PORT, --webdav-port WEBDAV_PORT                        WebDAV port of the server to authenticate to.

Example output

In attack mode (without --analyze option) you get the following output:


After all the RPC calls, you get plenty of authentications in Responder:
