black hat

Black hat refers to hakers who breaks into a computer system or network with malicious intent. A black hat hacker may exploit security vulnerabilities for monetary gain; to steal or destroy private data; or to alter, disrupt or shut down websites and networks. The black hat hacker may also sell these exploits to other criminal organizations. The term black hat differentiates criminal hackers from white and grey hat hackers. These categories were inspired by Western movies, where the heroes could be identified by the white hats they wore and the villains by their black hats.

Categories of hackers

A gray hat hacker operates with more ethical ambiguity — while they do not hack into systems with the malicious goal of stealing data, they may be willing to use illegal methods to find flaws, expose vulnerabilities to the public or sell to government and intelligence agencies.

A black hat hacker is typically one that engages in cybercrime operations and uses hacking for financial gain, cyberespionage purposes or other malicious motives.

Laws and penalties against black hat hacking

The term protected computer is large in scope, referring to a computer used by, for instance, a financial institution or the U.S. government for commerce or interstate and foreign communication.

TechTarget is responding to readers’ concerns as well as profound cultural changes. In some cases, we are defaulting to industry standards that may be seen as linguistically biased in instances where we have not found a replacement term. However, we are actively seeking out and giving preference to terms that properly convey meaning and intent without the potential to perpetuate negative stereotypes.
