I'm a student, but not a bug bounty hunter by any means. I've come across a few security bugs, nothing huge, and normally just send emails to the company with a quick note about what I've found. Every once in a while it leads to a little cash or so. I don't intentionally look for bugs, it just so happens that I enjoy poking other things to see what happens. The biggest bug I ever found was a wee-little searchbar error in LinekdIn (If typed a very specific gibberish string into the searchbar, you could crash Safari. To this day I'm still not exactly sure why), and instead of money, the guy offered me a job.

Am I student bug bounty hunter? No. I'm a student that sometimes breaks things and tells people when I do.
