White Hat / Black Hat Hackers

Cyber terms. White Hat hackers are hackers who perform hacking for legitimate reasons; e.g. IT Security technicians testing their systems and researchers testing the limits of systems. On the other hand, Black Hat hackers are those who perform clandestine hacking for malicious reasons; such persons can also be referred to as 'crackers'. Grey Hat Hackers are those who seems to fall between both camps and Red Hat Linux® is a real problem to classify!
