/PanARMENIAN.Net/ The Russian anti-virus vendor Doctor Web warns
users of a new virus, Trojan that deletes all files and directories
on a compromised computer. First cases of machines getting infected
by Trojan.KillFiles.904 have been registered in the first days of
June 2009. In a compromised system Trojan.KillFiles.904 searches for
local and removable drives in the reversed alphabetic order (from Z
to A). It removes all files and folders on available disks. If a file
can’t be deleted (e.g. it is being used) the Trojan will assign it
the "Hidden" attribute. The Trojan will delete all files and folders
except Windows system files and directories so a user can lose all
his data while his system is running the way it usually does. The
destructive feature makes the Trojan a unique piece of malware among
malicious programs of the present. While most of them aim to extort
money from a victim, KillFiles.904 won’t demand any investments into
the business of cyber-criminals nor it will try to steal anything –
its sole purpose is a complete removal of information stored in an
infected system. Perhaps, the Trojan is a successor of Win32.HLLW.Kati
(aka Penetrator) that damages Microsoft Word and Excel documents
as well as graphic and multimedia files. However, this species of
malware is far more dangerous, news.drweb.com reported.
