An iPhone feature that allows users to dial any phone number by simply tapping on a Web page could be exploited by hackers. As such, security researchers at SPI Labs are warning people not to use it, reports InfoWorld. They say the exploit could redirect calls to expensive "900" numbers, be used to track a user's calls, be stopped from dialing out or be set to dial out constantly, according to ZDNet blogger Ryan Naraine.
Lead researcher Billy Hoffman notes:
Because this vulnerability can be launched from Web sites, everybody who has an iPhone has the potential to get exploited.
Apple reportedly has not responded publicly to the security company's concerns.
