White, grey, and black hat hacking

According to Avast, white hat hackers are ethical security hackers who identify and fix vulnerabilities. These hackers usually break into systems with the permission of the organizations they hack into, as they attempt to uncover system weaknesses in order to fix them and help strengthen a system’s overall security. Many cybersecurity leaders started out as white hat hackers, but the vital role played by ethical hacking can still be widely misunderstood.

Grey hat hackers may not have criminal or malicious intent, but they also don’t have the prior knowledge or consent of those whose systems they hack into.  When grey hat hackers uncover weaknesses such as zero-day vulnerabilities, they usually report them to the parties in question instead of fully exploiting them. However, grey hat hackers could ask for payment in exchange for providing the full details of what they have discovered.

Black hat hackers are cybercriminals that break into systems illegally with malicious intent. Their main goal is to gain unauthorised access to computer systems by exploiting security vulnerabilities, or by implanting a virus or other type of malware such as a trojan. Black hat hackers often rely on ransomware attacks in order to extort financial gains or breach data systems.

In the case of, it could be argued that the breach resulted from a mix of white hat and grey hat techniques, as the hacker did not previously inform the victim of his attack. However, the hacker did not have malicious intent, as he returned the funds and provided details about what he has uncovered.
