The Hacker's Handbook is a legendary non-fiction book from the 1980s effectively explaining how computer systems of the period were hacked. It contains candid and personal comments from the book's claimed British author, Hugo Cornwall, although this is very likely to be a psyeudonym, with the author never making himself known.

The book was arguably most popular because of salactious print outs of actual hacking attempts (although confidential details, such as passwords, were blacked out).
