Security researcher PauloChoupina has already helped fix 47 vulnerabilities.



Researcher reputation:  120

Real name:
Paulo R. C. Choupina

About me:
http://paulochoupina.com/

I have been reporting bugs since 2013 before it was a tendency/trend.
Before platforms like Hackerone, BugCrowd, OpenBugBounty, etc.

Before all that, I was doing it on my own.

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

I try to be as active as one can.
My reported list includes: Nasa, GNU, .edu and .gov and some .pt (because I'm portuguese)

For any help or detailed info about the bugs, contact me!

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 nothing in return..

But of course, if you wanna thank me:

Anything is welcome.

Thanks in advance!
