New Virus Can Make Mobile Useless

Viruswarning_5I've just received some disturbing news from SimWorks about a brand new virus that can severely disable a Symbian Phone to the point where it is unusable. Gavno.a is spread under the file-name patch.sis and masquerades as a patch for Symbian OS phones.

Gavno.a cripples a phone by using a malformed file to crash an internal Symbian process. This file can cause enough damage to a Symbian phone that it can no longer be used to make phone calls and may never be able to fully boot-up again.

SimWorks have also identified a second version of Gavno named Gavno.b. It is identical to Gavno.a except that its installation file, patch_v2.sis is somewhat larger as its payload includes a copy of the Cabir and Camtimer Trojans. When Gavno.b is installed Cabir attempts to send a copy of Gavno and the Camtimer Trojan to other nearby Symbian phones via Bluetooth.

Gavno affects Series 60 phones using Symbian OS v7 such as the Nokia 6600 and 7610 and SimWorks CEO Aaron Davidson warns that:

“Once a user installs Gavno they may find it difficult if not impossible to repair. The instability that it introduces into the phone's operating system can be so severe that it effectively disables all applications on the phone and often results in the phone continually rebooting itself.”

The emergence of a more dangerous Symbian Virus (the previous Trojans such as Cabir and Skulls have been pretty toothless) has been anticipated for a few months and it comes as no surprise that someone has upped the ante by creating a Virus that actually disables the phone. Anti-Virus protection for mobile phones is slowly starting to become more necessary. SimWorks have already updated their Anti-Virus solution for Series 60 and UIQ based Symbian phones to cope with the Gavno trojans. You can get a copy of SimWorks Anti-Virus right here.

i think would be better that along with the name of the virus you also try to provide its actuall size in kilobytes or bytes so that we stay warned about files of specific sizes, cuz namez could be changed easily....well thats all thanx

Come on, this is more FUD. It's quite known that even ordinary applications can make the phone useless. So instead of wasting money on useless antivirus solutions, simply don't install software from unknown sources. More obvious, impossible.

Good point WaKaZzz:

- patch.sis is exactly 1,736 bytes; and
- patch_v2.sis is exactly 35,910 bytes.

Patch.sis contains the following text "Wonderful patch by artik100 :)".
