I’m Youssef, a Software Engineering student at McMaster and a bug bounty hunter on HackerOne since 2021. I started this blog to document my security research — both as a reference for myself and to share methodology with the community.

What I’ll Be Posting

  • Bug bounty writeups after disclosure is approved
  • Methodology breakdowns — how I approach recon, manual testing, and chaining vulnerabilities
  • CTF solutions from TryHackMe and other platforms
  • Android security research as I expand deeper into mobile

Why Write It Up?

Writing forces you to understand what you actually did vs. what you think you did. Half the time I’m drafting a writeup, I realize there’s a cleaner exploitation path I missed, or that my initial assumptions about impact were wrong.

It also builds a public track record. A portfolio of well-documented findings says more than a resume bullet point ever could.

More posts coming soon. Stay tuned.
