"I don't do a lot of CTF etc... due to the lack of realism but on this platform, the bugs are quite varied AND in a realistic environment, that's exactly what I'm looking for. I think this site is a good sequel for those who start on PortSwigger WebSecurity and / or TryHackMe."

Jimi Bloggs Level 4 BugBountyHunter Hacker, Jomar

Learning the mindset when testing web applications

Dubbed "BARKER", this website functions just like a real website except it contains real findings recreated for you to discover. Real findings from real bug bounty programs. "BARKER" is designed to put your knowledge & skills to the test as you're blindly hunting for functionality and features and you are required to understand what is happening, instead of "there is XSS here, can you bypass the filter?". There are no flags to find here either.

These are real features that function just like a real website would, login, register, post content, understand how things work and then use your knowledge to discover vulnerabilities, true hacker style! Question how things work and start testing! Your reports will be triaged by @zseano personally and help & feedback will be provided to help aid you in your hacker journey.

Learn how to identify vulnerabilities in websites at ease and understand more around application/business logic issues. Get an insight into the mistakes developers make.

Level up your confidence

Track your progress along the way and unlock perks as you level up your skill & discover more vulnerabilities.

Join us for Hackevents at Level 2 (25 unique bugs discovered on BARKER) where your skill is put to the test with a live hacking event with bounties to be won!

At Level 4 , (75 unique bugs discovered), receive our badge of recommendation and be shortlisted for private bug bounty program invites with our partner


BountyTraining are training videos we host on specific topics & a demo of applying them on bug bounty programs, such as what it means to actually "get a feel for things", or how to create a lead for yourself. These videos are open for all members and no level is required. We want to help you apply what you're learning out in the wild on real programs.

These videos will be available for the public shortly after.

zseano's methodology

The contents of this have been updated as of 31/05/2021

zseano's methodology is designed to be an easy to follow flow/checklist to help with identifying security vulnerabilities in web applications. Most people when starting in bug bounties will jump from program to program looking for anything they can, however focusing on one program and learing as much as you can about their scope & features will usually result in more bugs being discovered.

The guide contains a complete run-down of how zseano approaches hacking on web applications & how he applies this on bug bounty programs, including how to choose the right programs! From the very start with what he does when choosing a program, all the way to the end of what you should be aiming to automate to aid you in your hunting.

We believe zseano's methodology and BARKER go hand in hand because you can learn the flow and then begin instantly practising it on BARKER. Learn the flow, practise it, and then apply this on bug bounty programs. Take our hand and let us guide you and show it isn't as hard as it looks!

"The methodology has certainly made me think about the way I look at applications myself. It has helped me think better before starting an audit. What I still have trouble with is taking notes, I want to work on that even more. So far I am still too negligent about that. In any case, the methodology has given me an idea of how to tackle this. The way it is written is very accessible. Compared to other books on the same subject, the use of language is more in colloquialism than in technical writing. That is nice for a non-native English speaker like myself."
