Symbian Trojan threatens phones

by Nikola Strahija on July 4th, 2005 Virus writers have created a new Symbian Trojan called Doomboot-A that loads an earlier mobile virus (Commwarrior-B) onto vulnerable smartphones, which then prevents infected phones from booting up properly.


Symbian Series 60 smartphone users are at biggest risk, especially those who play around with pirated games. -Doomboot-A causes the phone not to boot anymore and Commwarrior causes so much Bluetooth traffic that the phone will run out of battery in less than one hour. Thus the user who gets his phone infected with Doomboot-A has less than one hour to figure out what is happening and disinfect his phone, or he will lose all data, writes Jarno Niemela, a researcher at Finnish anti-virus firm F-Secure.

-And what makes matters worse is that the Doomboot-A installation does not give any obvious clues that something is wrong, and Commwarrior-B does not have icon and is not visible in the process list. So the installation of Doomboot-A looks very much like failed installation of pirate copied game, and [a] user has hard time noticing that something bad is happening, he added.

Doomboot-A, like most Symbian Trojans, poses as a pirate copy of a Symbian game (in this case Doom 2). Users who avoid pirated games or applications should be safe from infection.
