Illicit computer intruders, or hackers, are often thought of as pathol
ogical individuals rather than as members of a community. However, hac
kers exist within social groups that provide expertise, support, train
ing, journals and conferences. This article outlines this community to
establish the nature of hacking within 'information societies'. To de
lineate a 'sociology of hackers', an introduction is provided to the n
ature of computer-mediated communication and the act of computer intru
sion, the hack. Following this the hacking community is explored in th
ree sections. First, a profile of the number of hackers and hacks is p
rovided by exploring available demographics. Second, an outline of its
culture is provided through a discussion of six different aspects of
the hacking community. The six aspects are technology, secrecy, anonym
ity, membership fluidity, male dominance and motivations. Third, an ex
ploration of the community's construction of a boundary, albeit fluid,
between itself and its other, the computer security industry, is prov
ided. This boundary is constructed through metaphors whose central rol
e is to establish the ethical nature of hacking. Finally, a conclusion
that rejects any pathologisation of hackers is offered.
