A grey hat (greyhat or gray hat) is a computer hacker or computer security expert who may sometimes violate laws or typical ethical standards, but usually does not have the malicious intent typical of a black hat hacker.
The term came into use in the late 1990s, and was derived from the concepts of "white hat" and "black hat" hackers.[1] When a white hat hacker discovers a vulnerability, they will exploit it only with permission and not divulge its existence until it has been fixed, whereas the black hat will illegally exploit it and/or tell others how to do so. The grey hat will neither illegally exploit it, nor tell others how to do so.[2]
A further difference among these types of hacker lies in their methods of discovering vulnerabilities. The white hat breaks into systems and networks at the request of their employer or with explicit permission for the purpose of determining how secure it is against hackers, whereas the black hat will break into any system or network in order to uncover sensitive information for personal gain. The grey hat generally has the skills and intent of the white hat but may break into any system or network without permission.[3][4]
According to one definition of a grey-hat hacker, when they discover a vulnerability, instead of telling the vendor how the exploit works, they may offer to repair it for a small fee. When one gains illegal access to a system or network, they may suggest to the system administrator that one of their friends be hired to fix the problem; however, this practice has been declining due to the increasing willingness of businesses to prosecute. Another definition of grey hat maintains that grey hat hackers only arguably violate the law in an effort to research and improve security: legality being set according to the particular ramifications of any hacks they participate in.[5]
In the search engine optimization (SEO) community, grey hat hackers are those who manipulate websites' search engine rankings using improper or unethical means but that are not considered search engine spam.[6]
A 2021 research study looked into the psychological characteristics of individuals that participate in hacking in the workforce. The findings indicate that grey hat hackers typically go against authority, black hat hackers have a strong tendency toward thrill-seeking, and white hat hackers often exhibit narcissistic traits.[7]
