Whitehat hacker

Also known as ethical hackers, these are usually cybersecurity specialists, researchers, or just skilled techies who find security vulnerabilities for companies and then notify them to issue a fix. Unlike blackhat hackers, they do not use the vulnerabilities except for demonstration purposes. Companies often hire whitehat hackers to test their security systems (known as “penetration testing”). As their expertise has grown to be more in demand and sought after, whitehat hackers started to collect rewards for their work, ranging from 500$ all the way to 100,000$.
