CHANGEME - Default credential scanner

October 25, 2017 , , , , , , , , , , ,
changeme picks up where commercial scanners leave off. It focuses on detecting default and backdoor credentials and not necessarily common credentials. It's default mode is to scan HTTP default credentials, but has support for other credentials.
changeme is designed to be simple to add new credentials without having to write any code or modules. changeme keeps credential data separate from code. All credentials are stored in yaml files so they can be both easily read by humans and processed by changeme. Credential files can be created by using the ./changeme.py --mkcred tool and answering a few questions.
changeme supports the http/https, mssql, mysql, postgres, ssh, ssh w/key, snmp, mongodb and ftp protocols. Use ./changeme.py --dump to output all of the currently available credentials.
You can load your targets using a variety of methods, single ip address/host, subnet, list of hosts, nmap xml file and Shodan query. All methods except for Shodan are loaded as a positional argument and the type is inferred.

Installation

changeme has only been tested on Linux and has known issues on Windows and OS X/macOS. Use docker to run changeme on the unsupported platforms. It supports either a redis-backed queue (most stable) or an in-memory backed queue.
Stable versions of changeme can be found on the releases page.
For mssql support, unixodbc-dev needs to be installed prior to installing the pyodbc.
PhantomJS is required in your PATH for HTML report screenshots.
Use pip to install the required python modules: pip install -r requirements.txt

Docker

A convenient way of running changeme is to do so inside a Docker container. You can run a pre-built container from Docker Hub, or build your own using the instructions below.

Run changeme in Docker

  1. Download the container: docker pull ztgrace/changeme
  2. Run the container: docker run -it ztgrace/changeme /bin/bash

Build from Dockerfile

  1. Build the docker container: docker build -t changeme .
  2. Run changeme from inside the container: `docker run -it changeme /bin/bash'

Usage Examples

Below are some common usage examples.
  • Scan a single host: ./changeme.py 192.168.59.100
  • Scan a subnet for default creds: ./changeme.py 192.168.59.0/24
  • Scan using an nmap file ./changeme.py subnet.xml
  • Scan a subnet for Tomcat default creds and set the timeout to 5 seconds: ./changeme.py -n "Apache Tomcat" --timeout 5 192.168.59.0/24
  • Use Shodan to populate a targets list and check them for default credentials: ./changeme.py --shodan_query "Server: SQ-WEBCAM" --shodan_key keygoeshere -c camera
  • Scan for SSH and known SSH keys: ./changeme.py --protocols ssh,ssh_key 192.168.59.0/24
  • Scan a host for SNMP creds using the protocol syntax: ./changeme.py snmp://192.168.1.20
See Wiki Examples for more detailed examples.
