OWASP Penetration Testing Kit troch pentestkit.co.uk

OWASP Penetration Testing Kit (PTK) is an open-source browser extension for interactive security testing of web applications.

PTK works from the live browser session where the application actually runs. This gives it access to the authenticated workflow, browser-generated traffic, loaded client-side code, application routes and runtime behaviour being tested.

Use OWASP PTK to:

Capture and inspect HTTP requests and responses generated by real browser workflows.
Run selected DAST checks against captured requests, parameters and request bodies.
Analyse JavaScript and HTML loaded by the browser for insecure patterns and source-to-sink data flows.
Observe security-relevant browser behaviour while the application executes using in-browser IAST.
Identify client-side libraries and known vulnerable versions with SCA.
Replay and modify requests with R-Builder, including cURL import and export.
Inspect, edit and test JSON Web Tokens.
Review cookies, browser storage, security headers, application technologies and discovered routes.
Encode, decode and transform data used during manual security testing.

Why test from the browser?

Authenticated applications and single-page applications often depend on state that is difficult to reproduce outside the browser. PTK tests the workflow you are currently using, including its identity, tokens, navigation, API traffic, DOM state and loaded client-side resources.

PTK provides its own extension interface and does not require browser DevTools. Its normal testing workflows do not require traffic to be routed through a separate desktop interception proxy.

For automation and CI/CD, use PTK Agent together with the separate PTK Auto browser extension. OWASP PTK also integrates with OWASP ZAP for combined browser-side and proxy-based security testing.

OWASP PTK is intended for penetration testers, bug bounty hunters, AppSec engineers, developers, QA engineers and security students.

OWASP PTK is free and open source.

Use PTK only against applications where you have explicit authorisation. Active scanning, request modification and token testing can modify application data, generate additional traffic and trigger security monitoring.
