First smartphone worm warning

All smartphone users look out. The antivirus company Kaspersky Labs has issued a report on Cabir, a worm that hits smartphones running on the Symbian operating system (which plenty of Nokia and Sony Ericsson phones use) and hops to other handsets via Bluetooth (which is probably an arduously slow and not very effective means of propagation). Luckily Cabir doesn't do any damage and is thought merely to be a proof-of-concept worm, which of course means that it's only a matter of time until a smartphone worm comes out that actually does some damage. In fact, there hasn't even been any evidence that anyone's phones have even infected with Cabir, the group that created the worm actually emailed it themselves to Kaspersky Labs and antivirus companies, probably to show off their skills.
