Kevin Mitnick, a onetime cult figure computer hacker, had the tables turned on him when his own site was attacked by a hacker who exploited a little-known vulnerability, his company said.

Mitnick, who served nearly five years in prison for stealing corporate computer secrets and was until recently prohibited from using computers under probation terms, took the attack in stride.

Mitnick said his site has attracted a number of attacks coming from almost every country since he launched the firm.
