Just like the Anti-virus companies predicted, with the increasing importance of mobile phones and PDA's more and more malicious code writers are turning their attention to writing code for these devices. Makes us wonder in fact if there is any credit to the old rumour of the same firms churning out virii to keep the company going.
In any case, the latest trojans are targetting the Symbian Operating system so once again its the majority of Nokia users who need to be the most careful. In warnings released by Symantec, the following descirptions of the malware were given out.
The Bootton.E Trojan horse was spotted last week by F-Secure and Symantec and is perhaps the most potentially crippling of the three to those infected. The program restarts the mobile device but it also releases corrupted components that cause the reboot to fail, leaving the device unusable. The Pbstealer.D Trojan sends an infected user's contact list, notepad, and calendar to-do list to other nearby users via Bluetooth. The third Trojan, Sendtool.A, sends malicious programs such as the Pbstealer Trojan to other devices via Bluetooth.
The good news?
Unlike worms on computers that spread without users knowing, the Trojan horses hitting cell phones spread as attachments that require users to download them.
The bad news?
So far, worms haven't hit mobile phones but it's very likely that people who write viruses are working on them, says Anton Von Trover, marketing manager for F-Secure.
