    I completed my second week as a full-time hunter. It's hard, but having @Rhynorater, @xssdoctor, @un1tycyb3r by your side makes it easy. Last month's stats (half as a full-time hunter): 2 crits triaged 2 highs triaged 1 crit pending triage 3 Google Cloud VRP bugs pending triage

    A few months ago, I began studying bug bounties extensively. I've made my list public, and you can submit links to help expand it!

    Are there any tools that check for reflected parameters from URLs and headers and are not Burp Pro extensions? Will I have to write my own?

    Just snagged my first @Hacker0x01 recon bounty thanks to @Jhaddix's course! Seriously, I just followed the slides, followed all those steps, and found what others missed! The course paid for itself 🎉
