The Cash for Clunkers program has already spawned its fair share of potential rip-offs online.

Unofficial websites are masquerading as the official Cash for Clunkers portal, according to an Associated Press report. These bogus sites will solicit personal information such as your Social Security number for supposed pre-registration…and then turn around and use it to steal your identity or money.

For those of you who may be unfamiliar, Cash for Clunkers is a new federal program offering rebates of up to $4,500 for trade-ins when you purchase a newer fuel-efficient vehicle.
