Gmail isn't just about e-mail anymore: it's also a phone. Google launched the ability to make voice calls to any traditional phone number from a Gmail account Wednesday. It's a blend of Gmail and Google Voice technology that allows users to dial numbers from their computers as well as receive incoming calls through one's Google Voice number. Gmail users can link their Google Voice accounts with their Gmail accounts to have their in-boxes treated like just another line that will ring when people call their Google Voice numbers, and their Google Voice number will appear on the incoming call screen of those they are calling. A Google Voice account isn't required to use the service, but international calls will be funded through Google Voice accounts. Calls to phone numbers in the U.S. and Canada will be free, and will cost 2 cents a minute to several other countries such as France and the U.K. The service should be rolling out to Gmail users in the U.S. on Wednesday, with international availability coming at an unspecified later date.

LAS VEGAS--Hackers competing in a social engineering contest at the Defcon conference here on Friday were able to trick random employees at 10 major U.S. tech, oil, and retail companies into giving them sensitive information over the phone that could be used in targeted computer attacks on the companies. "Every single company, if it was a security audit, would have failed," Christopher Hadnagy, operations manager for Offensive Security, a training and penetration testing company, told CNET after the first day of the contest, which wraps up Saturday and targets BP, Shell, Google, PG&E, Microsoft, Apple, Cisco, Ford, Coke, and Pepsi. "Not one company shut us down, although certain employees within the company did. But we (participants) were able to call right back and get another employee that was more willing to comply." The organizers declined to offer specific comments about any one of the companies targeted by the contest or say which companies are faring better or worse than the others. But they said they'd release a report with aggregated information in a few weeks. "The point isn't to shame anyone. It's to bring awareness to this attack vector, which is probably the easiest way to hack a corporation today," said Mati Aharoni, lead trainer at Offensive Security. "We really don't want to see anyone get harmed or get in trouble."
