Hacker in the context of "Hacker culture"

Neuromancer is a 1984 science fiction novel by American-Canadian author William Gibson. Set in a near-future dystopia, the narrative follows Case, a computer hacker enlisted into a crew by a powerful artificial intelligence and a traumatised former soldier to complete a high-stakes heist. It was Gibson's debut novel and, after its success, served as the first entry in the Sprawl trilogy, followed by Count Zero (1986) and Mona Lisa Overdrive (1988).

Gibson had primarily written countercultural short stories for science-fiction periodicals before Neuromancer. Influences on the novel include the detective stories of Raymond Chandler, the comic art of Jean Giraud, and William S. Burroughs's Naked Lunch (1959). Neuromancer expanded and popularised the setting and concepts of an earlier Gibson story, "Burning Chrome" (1981), which introduced cyberspace—a digital space traversable by humans—and "jacking in", a bio-mechanical method of interfacing with computers.

A security hacker or security researcher is someone who explores methods for breaching or bypassing defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, sabotage, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.

Longstanding controversy surrounds the meaning of the term "hacker". In this controversy, computer programmers reclaim the term hacker, arguing that it refers simply to someone with an advanced understanding of computers and computer networks, and that cracker is the more appropriate term for those who break into computers, whether computer criminals (black hats) or computer security experts (white hats). A 2014 article noted that "the black-hat meaning still prevails among the general public". The subculture that has evolved around hackers is often referred to as the "computer underground".

The hacker culture is a subculture of individuals who enjoy—often in collective effort—the intellectual challenge of creatively overcoming the limitations of software systems or electronic hardware (mostly digital electronics), to achieve novel and clever outcomes. The act of engaging in activities (such as programming or other media) in a spirit of playfulness and exploration is termed hacking. However, the defining characteristic of a hacker is not the activities performed themselves (e.g. programming), but how it is done and whether it is exciting and meaningful. Activities of playful cleverness can be said to have "hack value" and therefore the term "hacks" came about, with early examples including pranks at MIT done by students to demonstrate their technical aptitude and cleverness. The hacker culture originally emerged in academia in the 1960s around the Massachusetts Institute of Technology (MIT)'s Tech Model Railroad Club (TMRC) and MIT Artificial Intelligence Laboratory. Hacking originally involved entering restricted areas in a clever way without causing any major damage. Some famous hacks at the Massachusetts Institute of Technology were placing of a campus police cruiser on the roof of the Great Dome and converting the Great Dome into R2-D2.

Richard Stallman explains about hackers who program:

The Lazarus Group (also known as the Guardians of Peace or Whois Team) is a state-sponsored hacker group made up of unknown members, alleged to be run by the government of North Korea. While not much is known about the group, researchers have attributed many cyberattacks to them since the 2010s.

Originally deemed as a clandestine criminal group, the group has now been designated as an advanced persistent threat due to its intended nature, threat, and wide array of methods used when conducting an operation. Names given by cybersecurity organizations include Hidden Cobra (used by the United States Department of Homeland Security to refer to malicious cyber activity by the North Korean government in general), ZINC and Diamond Sleet (by Microsoft). According to North Korean defector Kim Kuk-song, the unit is internally known in North Korea as the 414 Liaison Office.

Barbara Joan Gordon is a superheroine appearing in American comic books published by DC Comics, commonly in association with the superhero Batman. The character was created by television producer William Dozier, editor Julius Schwartz, writer Gardner Fox, and artist Carmine Infantino. Dozier, the producer of the 1960s Batman television series, requested Schwartz to call for a new female counterpart to the superhero Batman that could be introduced into publication and the third season of the show simultaneously. The character subsequently made her first comic-book appearance as Batgirl in Detective Comics #359, titled "The Million Dollar Debut of Batgirl!" in January 1967, by Fox and Infantino, allowing her to be introduced into the television series, portrayed by actress Yvonne Craig, in the season 3 premiere "Enter Batgirl, Exit Penguin", in September that same year.

Barbara Gordon is the daughter of Gotham City police commissioner James Gordon, the sister of serial killer James Gordon Jr. and is initially employed as head of the Gotham City Public Library. Although the character appeared in various DC Comics publications, she was prominently featured in Batman Family which debuted in 1975, partnered with the original Robin, Dick Grayson, whom she has a history of working closely and being romantically involved with. In 1988, following the editorial retirement of the character's Batgirl persona in Batgirl Special #1, the graphic novel Batman: The Killing Joke depicts the Joker shooting her through the spinal cord in her civilian identity, resulting in paraplegia. In subsequent stories, the character was reestablished as a technical advisor, computer expert and information broker known as Oracle. Becoming a valuable asset providing intelligence and computer hacking services to assist other superheroes, she makes her first appearance as Oracle in Suicide Squad #23 (1989) and later became a featured lead of the Birds of Prey series. In 2011, as part of DC Comics The New 52 relaunch, Barbara recovered from her paralysis following a surgical procedure and returned as Batgirl. Barbara has since featured in the eponymous Batgirl monthly title as well as Birds of Prey and other Batman books. Following the events of Joker War, Barbara returned to her Oracle role while recovering from an injury, and continues to operate as both Batgirl and Oracle after the 2021 Infinite Frontier event.
