πŸ“‚ Projects

Web Penetration Testing

During the web penetration test, multiple security vulnerabilities were identified, including XSS, authentication bypass, SSTI etc. These issues allow attackers to potentially execute arbitrary scripts, gain unauthorized access, and perform server‑level code execution. The findings highlight weaknesses in input validation, session handling, and template rendering mechanisms.

Manual Testing

Manual testing of the 'D-Money financial service' website is conducted through exploratory testing. In this approach, I interact with the website by simulating real-world usage to identify functional, usability, and performance issues. This testing allows me to uncover edge cases, unexpected bugs, and areas for improvement that automated tests might overlook.
