iPhone dials by remote control
The Fraunhofer Institute for Secure Information Technology (SIT) reports it has found a security hole in the iPhone which allows a web page to make the mobile phone dial arbitrary phone numbers. It appears that users can't abort the dialling process; the iPhone no longer responds to the home key and other key inputs.
That the Safari iPhone browser allows phone numbers to be dialled directly via tel: links has been discussed as a potential problem for quite some time. In September 2007, Apple released the iPhone v1.1.1 update in an attempt to stop links from being exploited for unwanted calls – it seems this measure wasn't entirely successful.
