Summary
🤩
Rockstar🎓
Top SchoolYunus Aydın is an Application Security Engineer based in Istanbul with six years of hands-on experience in security research and AppSec. He combines practical vulnerability hunting with secure development practices, contributing to projects such as CodeQL where he worked on Swift path-injection checks tied to CWE-22. Yunus has built and extended offensive tooling—adding persistence, multi-input capture, and exfiltration features to a Python-based keylogger—giving him a pragmatic perspective on threat techniques and detection evasion. Comfortable moving between code-level fixes and adversary simulation, he focuses on actionable mitigations that reduce real-world risk. A strong communicator with a solid academic foundation from İstanbul Ticaret Üniversitesi, he brings both research curiosity and operational experience to security programs. Notably, his open-source contributions reflect a balance of defensive code analysis and hands-on exploit development, informing more robust AppSec controls.
