REST-Attacker – Designed As A Proof-Of-Concept For The Feasibility Of Testing Generic Real-World REST Implementations

REST-Attacker is an automated penetration testing framework for APIs following the REST architecture style. The tool’s focus is on streamlining the analysis of generic REST API implementations by completely automating the testing process – including test generation, access control handling, and report generation – with minimal configuration effort. Additionally, REST-Attacker is designed to be flexible and extensible with support for both large-scale testing and fine-grained analysis.

REST-Attacker is maintained by the Chair of Network & Data Security of the Ruhr University of Bochum.


REST-Attacker currently provides these features:

  • Automated generation of tests
    • Utilize an OpenAPI description to automatically generate test runs
    • 32 integrated security tests based on OWASP and other scientific contributions
    • Built-in creation of security reports
  • Streamlined API communication
    • Custom request interface for the REST security use case (based on the Python3 requests module)
    • Communicate with any generic REST API
  • Handling of access control
    • Background authentication/authorization with API
    • Support for the most popular access control mechanisms: OAuth2, HTTP Basic Auth, API keys and more
  • Easy to use & extend
    • Usable as standalone (CLI) tool or as a module
    • Adapt test runs to specific APIs with extensive configuration options
    • Create custom test cases or access control schemes with the tool’s interfaces


Get the tool by downloading or cloning the repository:

git clone

You need Python >3.10 for running the tool.

You also need to install the following packages with pip:

python3 -m pip install -r requirements.txt


Here you can find a quick rundown of the most common and useful commands. You can find more information on each command and other about available configuration options in our usage guides.

Get the list of supported test cases:

python3 -m rest_attacker --list

Basic test run (with load-time test case generation):

python3 -m rest_attacker <cfg-dir-or-openapi-file> --generate

Full test run (with load-time and runtime test case generation + rate limit handling):

python3 -m rest_attacker <cfg-dir-or-openapi-file> --generate --propose --handle-limits

Test run with only selected test cases (only generates test cases for test cases scopes.TestTokenRequestScopeOmit and resources.FindSecurityParameters):

python3 -m rest_attacker <cfg-dir-or-openapi-file> --generate --test-cases scopes.TestTokenRequestScopeOmit resources.FindSecurityParameters

Rerun a test run from a report:

python3 -m rest_attacker <cfg-dir-or-openapi-file> --run /path/to/report.json


Usage guides and configuration format documentation can be found in the documentation subfolders.
