PauloChoupina | Security Researcher Profile


Security researcher PauloChoupina has already helped fix 74 vulnerabilities.



Researcher reputation:  130

Real name:
Paulo R. C. Choupina

About me:
http://paulochoupina.com/

Started reporting bugs on my own in 2013 before platforms like Hackerone, BugCrowd and OpenBugBounty etc, existed.

Now is much easier.
Back then, people just didn't knew what an ethical hacker was.

Acknowledged by Microsoft, OLX, Sapo, Huawei and many more.

My report list includes only the best bugs I've found.

Please check them out.



ps: I only report my own bugs and I try to be as active as I can.

How to contact me:
Via email: [email protected]

Experience in Application Security
over 5 years

Award / Bug Bounty I prefer:
Most people don't give anything.
And thats ok, I don't expect much in return..

Just a good review in my profile would be enough.

But of course, if you wanna support me, anything is welcome.
