Black hat

A black hat hacker is a hacker who "violates computer security for little reason beyond maliciousness or for personal gain." Black hat hackers form the stereotypical, illegal hacking groups often portrayed in popular culture, and are "the epitome of all that the public fears in a computer criminal". Black hat hackers break into secure networks to destroy, modify, or steal data; or to make the network unusable for those who are authorized to use the network. Black hat hackers are also referred to as the "crackers" within the security industry and by modern programmers. Crackers keep the awareness of the vulnerabilities to themselves and do not notify the general public or the manufacturer for patches to be applied. Individual freedom and accessibility is promoted over privacy and security. Once they have gained control over a system, they may apply patches or fixes to the system only to keep their reigning control.

Richard Stallman invented the definition to express the maliciousness of a criminal hacker versus a white hat hacker who performs hacking duties to identify places to repair.

Haredi Judaism

Haredi Judaism (Hebrew: חֲרֵדִי Ḥaredi, IPA: [χaʁeˈdi]; also spelled Charedi, plural Charedim) is a stream of Orthodox Judaism characterized by rejection of modern secular culture. Its members are often referred to as strictly Orthodox or ultra-Orthodox in English. The term "ultra-Orthodox," however, is considered a derogatory slur by some in the community. Haredim regard themselves as the most religiously authentic group of Jews, although this claim is contested by other streams.

Haredi Judaism emerged in response to the sweeping changes brought upon the Jews in the modern era: emancipation, Enlightenment and the Haskalah movement derived from it, acculturation, secularization, religious Reform in all its forms, Jewish nationalism, etc. In contrast to Modern Orthodox Judaism, which hastened to embrace modernity, the approach of the Haredim was to maintain a steadfast adherence to Jewish religious law by segregating itself from modern society. However, there are Haredi communities in which getting a professional degree and a trade is encouraged and contact exists between Haredi and non-Haredi Jews.
