writes "A DefCon contest that invites contestants to trick employees at 30 US corporations into revealing not-so-sensitive data has rattled nerves at the FBI. Chris Hadnagy, who is organizing the contest, also noted concerns from the financial industry, which fears hackers will target personal information. The contest will run for three days, with participants attempting to unearth data from an undisclosed list of about 30 US companies. The contest will take place in a room in the Riviera hotel in Las Vegas furnished with a soundproof booth and a speaker, so an audience can hear the contestants call companies and try to weasel out what data they can get from unwitting employees."
The group organizing the contest has established a strict set of rules
to ensure participants don't violate any laws. Update: 07/31 04:45 GMT
