In contrast to black hat hackers, white hat hackers do not have malicious intent and instead intend to provide beneficial "insider information" from a hacker's perspective so that companies may adjust their security accordingly and prevent breaches or other forms of cyber attacks. While many white hat hackers have informed companies of such vulnerabilities without any expectation of monetary reward, other companies have taken the step of offering money or other "prizes" for those who are able to detect and report previously unknown security issues.
