Hola
En el artículo confunden el termino Hacker con Cracker ahi donde escriben:
"No es un ‘hacker’
Las películas de Hollywood han hecho creer que los ingenieros de sistemas son tan ‘capos’ que pueden ingresar a cualquier sistema y hacer de las suyas."
Ya que de acuerdo al
RFC 1392: Internet Users’ Glossary http://tools.ietf.org/html/rfc1392 cracker A cracker is an individual who attempts to access computer systems
without authorization. These individuals are often malicious, as
opposed to hackers, and have many means at their disposal for
breaking into a system. See also: hacker, Computer Emergency
Response Team, Trojan Horse, virus, worm.
hacker A person who delights in having an intimate understanding of the
internal workings of a system, computers and computer networks in
particular. The term is often misused in a pejorative context,
where "cracker" would be the correct term. See also: cracker.
