A GraphQL request can look harmless in Burp. But if it triggers repeated resolver execution, the backend cost can explode. That’s why the $12,500 DoS report is worth studying. Small request ≠ small impact. Read the breakdown: medium.com/@Aacle/how-graphq…

Not every packet leaving your browser is data exfiltration. Saw a funny Reddit post about fake “critical” bug bounty reports. It was a joke. But honestly, it points to a real beginner mistake. 1/7 :thread

Before submitting, ask: Can I reproduce it cleanly? Can I explain it in one sentence? Can I show attacker impact? Can I prove this is not normal behavior? Can the dev fix it without guessing? If no, the report is not ready. 6/7

Bug bounty lesson: Don’t make the bug sound scary. Make it easy to verify. A simple, reproducible medium-severity report is better than a dramatic “critical” report with no real impact.

$600k in 6 months from one hardened target is wild. But the bigger lesson: security gaps rarely look obvious from inside the product. Fresh eyes deep curiosity still beat checkbox security.
$600k in ONLY 6 MONTHS? Let's chat more about @brutecat's journey hacking one of the most hardened companies in the world! youtu.be/xZe7bBC17TM

Did you know I had a 10-part feature series on the Bugcrowd blog back in 2021? The good old days! I went from $100 (first payout in 2020) to being #1 or #2 on the platform in 2025 for lifetime bounties earned, it was a pretty crazy run and countless hours of work. But I'm totally burnt-out on all the red-tape and humanity in the process. If you are in the field, stay positive as long as you can, and if you don't have it, develop patience... massive quantities of patience. #bugbounty And when your patience finally burns out, there's always day trading, still uses the 12345. bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip… bugcrowd.com/blog/zwinks-tip…

A $12,500 HackerOne bounty came from a bug that didn’t steal data. → No account takeover. → No IDOR. → No RCE. Just one GraphQL request making the server work much harder than it should. That’s what makes this report worth studying. 1/10 medium.com/@Aacle/how-graphq…

9/10 I broke down the full report in a beginner-friendly way: → what GraphQL aliases are → why mutation aliasing can cause DoS → how the reporter proved impact → why the triager asked for more impact → what developers can do to fix it

If you’re learning bug bounty or GraphQL security, read this one slowly. It’s a good example of how impact comes from thinking about backend cost, not just access control. Full Medium breakdown here: medium.com/@Aacle/how-graphq…
