Attack of the skulls!

With every advancement of mobile technology, comes a down side. Basically, this means that it might be time to start looking at an antivirus for your mobile phone, folks. Yes, apparently there is a Skull Trojan horse floating around out there. And guess what, it is looking for a mobile phone just like yours to call home!

F-Secure has reported that Skulls.D kills off all system applications, as did previous variants. But rather than turning individual application icons into skulls, as the first version of the malicious software did, Skulls.D tells people their cell phones have been infected by displaying a full-screen flashing skull, the security software maker said on Monday.

The first Skulls variant was discovered at the end of November. A later version was packaged with the cell phone virus Cabir.

The new Skulls variant pretends to be Macromedia Flash player and affects Symbian Series 60 devices. People whose handsets have been infected cannot run programs, take pictures or send text messages, although they can still make phone calls, F-Secure said.

The Trojan horse also prevents people from installing new applications, so the majority of people with infected handsets will need to reset their phone. This will leave the phone in its default factory condition and delete data such as address books.
