Fraudsters called AT&T (formerly known as SBC) and claimed that phones were not working in pizza restaurants, and persuaded a customer service rep to forward calls to a different phone number.
Calls for pizzas reached crooks, who made believe they were taking orders, and collected credit card information that was then used to make fraudulent internet purchases under the names of unsuspecting pizza customers.
Two incidents of the scam have been reported in California, but it's unclear if the ruse has been replicated elsewhere. The trouble became apparent when pizzerias complained that their phones had stopped ringing. AT&T failed to make any checks before forwarding the calls, but says it has instituted extra precautions and that subsequent attempts to pull off the con have failed. (from TheRegister.com)
