Nimbus Hosting lists some of the world's most successful and profitable bug bounty hunters.
Not all hackers are evil, some of them do fight to keep the internet safe. Most of the good guys do it for the bounties offered by major brands and net companies.
After spotting a loophole in its security coding for OpenID, Facebook paid Reginaldo Silva of Brazil $33,500 (£23,665) for his troubles.
The practice is so widespread, that some ethical hackers make a living out if it. Russian student Sergey Glazunen earned $145,000 (£102,430) for noticing 59 bugs in Google Chrome's coding from 2012-2013.
Remember, not all hackers are out to steal credit card information and personal details.
