I Gave Claude 12 Years of my Bug Bounty Reports - Here's What I Learned

BLUF: After analyzing 1,500 bug bounty reports over 12 years, the author reveals that success stems not from finding "harder" bugs, but from shifting to high-signal bug classes like subdomain takeover and executing systematic campaigns across multiple targets, rather than hunting individual vulnerabilities.
Key Takeaways:
• The Reality of Early Career: In 2014, the author submitted 173 reports with only a 16% paid rate, contrasting sharply with 2019’s 75% paid rate on 112 reports 2:32. This improvement came from filtering submissions, not just finding better bugs.
• Bug Classes Have Evolved: Classic vulnerabilities like CSRF, SQLi, and standalone information disclosures have dropped to zero for the author because modern frameworks (Rails, Django, React) patch them by default 6:01. Hunters must adapt to where the vulnerabilities still exist.
• Signal Rate vs. Fame: Subdomain takeover has a 90% signal rate and low duplicate rates, making it highly reliable, whereas Remote Code Execution (RCE) has a lower signal rate (62%) and often fails due to disputed impact (e.g., sandboxing) rather than being found first 9:03.
• The Power of Campaigns: Success is driven by "campaigns"—finding one primitive vulnerability and sweeping it across dozens of targets. For example, injecting payloads into "name" fields worked across 33 programs over 10 years by exploiting similar object handling 13:15.
• Outdated Tech is a Goldmine: A campaign targeting outdated Chromium versions in headless browsers, Electron apps, and embedded devices yielded results across 10 programs in 4 months by exploiting known CVEs in legacy rendering engines 14:21.
The data underscores that bug bounty hunting is a long-term game of pattern recognition and persistence. While short-term variance can be discouraging, the cumulative effect of systematic campaigns and adapting to the changing landscape of web security yields significant results over a decade.

I've never been able to look at my own entire bug bounty career with honestly. 12 years in and every time I look back, I'm always remembering the highlight reel. So, this time I stopped trusting my own memory. I took every report I've ever submitted to HackerOne, all 1,500 of them, 228 programs, February of 2014 through November of 2025, and I handed the entire pile to a machine. I read it all through AI, classified every bug, lined up every outcome, and I told it to not protect my feelings about any of it. It came back with three things that I didn't want to hear. That the bug class I'm most known for, I stopped finding years ago. That the bug I'd almost be embarrassed to submit lands way more often than the one that I give a conference talk about. And that 561 of those 1,500 reports went…
