"Disker" and "Disker64" trojan

[aztec 0]

Hi,

 

Saw this on the World of Warcraft/Blizzard games forum yesterday:

 

http://us.battle.net/wow/en/forum/topic/11041384892?page=1

 

Wondered if Emsi has been notified of this new malware, and has tried to mitigate it?

 

 

Thanks.

Yes, we are aware of it and detect/remove it. I can confirm the objects listed in the article you linked to are being created as stated: If you are concerned you have this malware and you have HijackFree, you can see the objects (Disker and/or Disker64) under the Autoruns tab.

Thank you Elise for the quick reply and the good work.

This file is undetected by Emsisoft:

 

setup.exe - https://www.virustotal.com/en/file/09943ba819c2f70899dfa16d2930c65b4170989de9bf7de8b2cdaf15d137a7c1/analysis/1388832922/

 

Some other antivirus products with BitDefender engine detect it, but Emsisoft does not

 

It drops WINDOW~1.EXE and WINDOW~1.EXE drops w_win.dll and w_64.DLL.

 

WINDOW~1.EXE, w_win.dll, w_64.DLL - these files are detected.

I'll submit the undetected files.

There are a number of variants, which is while some hashes are undetected. However trace detection is present for all dropped components.
