Installation to system
When the worm's file is run, it first shows a fake error messagebox:
Error
The file could not be opened!
Then the worm copies itself to Windows directory with SERVICES.EXE name and creates a startup key for this file in System Registry:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"service" = "%windir%\services.exe -serv"
where %windir% represents Windows directory. At the same time the worm also attempts to delete the following key values:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Taskmon"
"Explorer"
"system."
"KasperskyAv"
[HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Taskmon"
"Explorer"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices]
"system."
[HKCR\CLSID\{E6FB5E20-DE35-11CF-9C87-00AA005127ED}\InProcServer32]
After that the worm starts looking for email addresses. It scans files with the following extensions on all available drives (c:-z:) except CD-ROM drives:
.msg
.oft
.sht
.dbx
.tbb
.adb
.doc
.wab
.asp
.uin
.rtf
.vbs
.html
.htm
.pl
.php
.txt
.eml
If the worm finds a folder with the 'sharing' or 'share' name, it copies itself to that folder with the following names:
winxp_crack.exe
dolly_buster.jpg.pif
strippoker.exe
photoshop 9 crack.exe
matrix.scr
