white hat vs black hat

This article is about computer hackers

White hat

A white hat is the hero or good guy, especially in computing slang, where it refers to an ethical hacker or penetration tester who focuses on securing and protecting IT systems.

White hat hackers are computer security experts, who specialize in penetration testing, and other testing methodologies, to ensure that a company’s information systems are secure. White hat hackers are also called “sneakers”, red teams, or tiger teams. These security experts may utilize a variety of methods to carry out their tests, including social engineering tactics, use of hacking tools, such as Metasploit, which exploits known vulnerabilities, and attempts to evade security to gain entry into secured areas.

Black hat

Black hat is used to describe a hacker (or, if you prefer, cracker) who breaks into a computer system or network with malicious intent. Unlike a white hat hacker, the black hat hacker takes advantage of the break-in, perhaps destroying files or stealing data for some future purpose. The black hat hacker may also make the exploit known to other hackers and/or the public without notifying the victim. This gives others the opportunity to exploit the vulnerability before the organization is able to secure it.
