WS-Attacker

Penetration testers focusing on SOAP and REST API security will get the most from WS-Attacker because its modular attack library lets you chain custom payloads against web service implementations that standard HTTP proxies miss. The framework supports 15+ distinct attack types including XML signature wrapping and WSDL manipulation, and its 491 GitHub stars reflect active community maintenance. Skip it if your team needs a commercial support contract or a clickable UI; this is a command-line framework that rewards practitioners who read the documentation and write their own modules.
