At the age of 21, he hacked into the files of the Griffiss Air Force Base Research Laboratory in New York.

[1] Bullied by his peers,[3] Bevan had a difficult time with school and at night he would turn to the online world as an escape.

Bevan began to lead a double-life[citation needed], going to school during the day, then later engaging in the nocturnal hacking activities which were eventually discovered.

A statement by the United States Senate Permanent Subcommittee on Investigations declared that Bevan, identified by his pseudonym 'Kuji', was a "Foreign Agent, possibly of Eastern European origin".

On 21 June 1996, Bevan was arrested for hacking into sensitive USAF, NASA, and NATO facilities.
