Short Description
changeme default credential scanner.
Full Description


A default credential scanner.


I wrote changeme out of frustration with commercial vulnerability scanners missing common default credentials. Getting default credentials added to commercial scanners is often difficult and slow. 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 ./ --mkcred tool and answering a few questions.

changeme supports the http/https, mssql, mysql, postgres, ssh and ssh w/key protocols. Use ./ --dump to output all of the currently available credentials.


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.

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.

Use pip to install the python modules: pip install -r requirements.txt


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

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

Usage Examples

Scan a subnet for default creds: ./ -s

Scan a single host: ./ -s

Scan using an nmap file ./ -x subnet.xml

Scan a subnet for Tomcat default creds and set the timeout to 5 seconds: ./ -s -n "Apache Tomcat" --timeout 5

Use Shodan to populate a targets list and check them for default credentials: ./ --shodan_query "Server: SQ-WEBCAM" --shodan_key keygoeshere -c camera

Scan for SSH and known SSH keys ./ -s --protocols ssh,ssh_key

Known Issues

The ftp, mssql, and telnet scanners are broken.
