Fifteen Famous Bug Bounty Hunters
Fifteen Famous Bug Bounty Hunters
For today’s article, let us acknowledge fifteen famous and 1337 bug bounty hunters who have been the talk of the web. This list does, not enumerate all the top bug bounty hunters in top crowdsourcing platforms like Bugcrowd, Hackerone and Cobalt (formerly Crowdcurity), but people who have proven to be worthy of their contribution and have embodied the true hacker culture – although some people who have topped in the leaderboard will also be enumerated.
The goal is not to list people who topped the leaderboard in Bug Bounty programs just because of the number of vulnerabilities they submitted, which could be inaccurate. This is in honor of Bugcrowd’s “State of Bug Bounty” PDF report.
Bugcrowd’s “The State of Bug Bounty” reports:
A self-employed “security researcher” based in Pakistan was the most prolific submitter overall with a submission count of 1,094—nearly three times that of the points leader and nearly four times that of the top paid researcher. This is especially noteworthy given his first submission wasn’t until February 18, 2014—roughly a year later than the points and rewards leaders.
While his 1,094 submissions make him the top submitter out of the entire research community, a well below average priority rating of 4.42 and a very low total average reward per valid submission of $20.54 make this researcher very noisy. These figures suggest that this researcher uses a shotgun approach for finding and submitting bugs, even if the issues found end up being flagged as invalid bugs. Further proving this hypothesis is the fact that this researcher possesses an extremely low 4% acceptance rate for his submissions.
Given these figures, one might come to the conclusion that this researcher puts a higher value on submission count notoriety over rewards—with 120 Hall of Fame entries, it would be hard to argue this point. So, while very proactive and active, simply put, this researcher submits things that aren’t as valuable as other researchers’ submissions. The top, in this case, is far noisier than signal desired.
Names are not arranged to their ranking. Alright, let’s start!
Drum roll please…
- Stéphane Chazelas
Stéphane is a *nix and Telecom Specialist who discovered the GNU Bourne-Again Shell (Bash) Shellshock vulnerability. He is also involved in the UNIX and Free Software/Open Source community (writings, contributions to projects). He reported Shellshock in Hackreone and was rewarded with $20,000 USD for his responsible disclosure.
- Rafay Baloch
Rafay is a Pakistani independent security researcher who owns rafayhackingarticles.net. He once found a remote code execution vulnerability inside PayPal for which he was awarded $10,000 USD and also was offered a job by PayPal, but turned down the job offer. Rafay is an active participant in bug bounty programs and is listed in large number of hall of fames including Google, Facebook Microsoft, Twitter, and Dropbox. He is best known for discovering Android Stock Browser Address Bar Spoofing, which affected Android Lollipop and previous versions.
- Frans Rosén
Frans is currently the second in rank for the top bug bounty hunters in Hackerone. He is a Dev/Security/Founder at Detectify. He was interviewed by Adam Crouchley for finding a flash-based XSS vulnerability in Mega which scored him a €1,000. Kind of big for a SWF issue but still a good find though. He has reported many security vulnerabilities wherein he was rewarded with a large amount of money.
- Jason Haddix
Aside from being the former top bug bounty hunter in Bugcrowd, Jason is currently the Director of TechOps in Bugcrowd. Together with Daniel Miessler, they head the OWASP IoT, OWASP SecLists and OWASP Mobile Top Ten projects. He is a great web and mobile hacker.

- Roy Castillo
Roy is a Filipino bug bounty hunter who reported stored XSS in Gmail for iOS, and is known for reporting a bug in Facebook that exposes primary Facebook email addresses. He is considered as one of the first Filipinos to have participated in Bug Bounty Programs. Prior to his fame in bug bounty hunting, he took an advantage of a XSS in Facebook that allows outsiders to add scripts to Web pages. His status “Off to Danao City” swarmed some Facebook users because it couldn’t be deleted, and Roy couldn’t be blocked — because he wasn’t in the friend’s lists of the profiles on which he appeared. Kinda naughty LOL.
- Emily Stark
Bitquark is also a former ranked #1 bug bounty hunter just like Jason Haddix. Although not much is known about his personal life, he has shared a lot of ass kicking security bugs disclosed in his blog ‘bitquark.co.uk’. Google’s ‘Google Sites’ rewarded him a total of $13,034.80 for his five bugs.
