We've heard rumours from two different sources that the Cabir mobile phone virus would be in the wild.
We've been unable to confirm this so far, but in any case we're recomming users of all mobile phones with a Symbian Series 60 operating system to keep their Bluetooth in non-discoverable mode. If you don't understand what this means, just turn off Bluetooth.
This includes phones from manufacturers such as Nokia, Siemes, Panasonic and Sendo.
Cabir is the first mobile phone virus in history. It was originally discovered in the middle of June 2004, but it has never been seen in the wild. It attempts to spreads over Bluetooth connections to compatible phones nearby.
