Development of Infrastructure Attack Detection and Analysis Tools Based on OWASP Vulnerabilities

Project Manager | 2024
Private repo for security policy

Classify attacks based on OWASP vulnerabilities and perform web and network attacks exploiting these vulnerabilities to collect data. By training this data with AI, it becomes possible to detect the latest vulnerability-based attacks through web server logs.


Web-based 0/1-Day Vulnerabilities and Development of Semi-automated Tools

Project Manager | 2024
Private repo for security policy

Collected 1-Day vulnerabilities of major frameworks and created additional PoC codes, storing them in a database. Developed a tool to manage various vulnerabilities, perform attack tests on targeted servers, and propose security solutions.
