Details
IRC-Worm.Evion
IRC-Worm.Evion Evion is an IRC worm spreading via IRC channels. The virus is written in Visual Basic Script (VBS). It overwrites .vbs and .html files on all local and mapped drives.
Installing:
When the worm is executed it does the following:
Evion creates copies of itself in the root directory of disk C: in the file "Win32 Strt.exe.vbs " and in the system directory file "BootLoader.exe.vbs" as well as in the root Windows directory in the files"Jokes.htm" and "Winupdate.exe"
Evion overwrites these existing files with a copies of itself:
%Windir%Readme.htm
%Windir%Htmlhelp.htm
%System%Winhelp32.exe
%Mirc%script.ini
Evion registers the files "BootLoader.exe.vbs" and "Win32 Strt.EXE" in the automatic launch string of the system registry:
HKEY_LOCAL_MACHINEMicrosoftWindowsCurrentVersionRun - (BootLoader.exe.vbs)
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServices - (Win32 Strt.EXE)
Spreading
Evion searches for the all .vbs files and overwrites the existing .vbs files with a copies of itself. Files that have the extensions .htm, .html, .asp, .htx, and .hta are replaced with the .HTML version of the worm.
The "Script.ini" file is a short mIRC program that sends the %Windir%Jokes.htm file to everybody who enters an infected channel.
Payload
The worm activates its payload three different days (October 15th, November 23rd and December 25th), and displays a Message Box with the following respective texts:
with Message box title "my b-day" and text "happy birthday kefi" - 15 october
with Message box title "11/23!" and text "holy sh*t! it's 11/23" - 23 november
with Message box title "kefi [rRlf]" and text "Organized religion controls the world" - 25 december
On these payload activation days the worm also creates 16 text files in the Windows Startup folder. The file name uses the format: StartupEvion(n).txt, where n is between 0 and 15 (inclusive). These files contain 50 text strings of randomly generated text that is selected from these three lines:
You've done and gotten your self infected with Vbs.Evion by kefi [rRlf] [rRlf] ownz joo bitch Catfish_VX are lamers. This virus was constructed for them to steal
On days other than the ones on which the payload runs, a text document is created in the Desktop Windows directory. The file name uses the format "Desktop%day% - %month%.vir.txt".
These files contain the following text:
