Produced structured penetration testing reports
Performed manual API testing using Burp Suite, Postman collections & environments, JSON payload manipulation, header tampering, and parameter fuzzing.
Evaluated API access controls, data exposure risks, and improper rate limiting mechanisms
Conducted passive reconnaissance by analyzing API documentation, endpoint structures, HTTP responses, and exposed metadata
Performed active reconnaissance to enumerate hidden endpoints, test parameters, and identify misconfigured routes
Used interception proxy tools to capture, inspect, and manipulate live HTTP/HTTPS requests and responses.
Used Burp Repeater to manually modify and replay API requests for authorization and logic testing
Leveraged Burp Intruder to automate parameter fuzzing, test IDOR patterns, and analyze rate-limiting weaknesses
Utilized Burp Sequencer to assess randomness and entropy of session tokens and authentication mechanisms
