Virus Characteristics
This is a VBScript worm with virus qualities. This worm will arrive in an email message with this format:
Subject "ILOVEYOU"
If the user runs the attachment the worm runs using the Windows Scripting Host program. This is not normally present on Windows 95 or Windows NT unless Internet Explorer 5 is installed.
When the worm is first run it drops copies of itself and writes an .HTM file in the following places :
WINDOWS\SYSTEM\MSKERNEL32.VBS
It also adds the registry keys :
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices\
in order to run the worm at system startup.
This worm searches all drives connected to the host system and replaces the following files:
*.JPG
with copies of itself and it adds the extension .VBS to the original filename. So PICT.JPG would be replaced with PICT.JPG.VBS and this would contain the worm.
The worm also overwrites the following files:
*.VBS
with copies of itself and renames the files to *.VBS.
This virus locates instances of the following file types:
*.MP3
and if found, makes them hidden and copies itself as these filenames except with .VBS extension. For instance, if file exists as "2PAC.MP3", this now becomes a hidden file and the virus is copied as "2PAC.MP3.VBS".
The worm creates a file "LOVE-LETTER-FOR-YOU.HTM" which contains the worm and this is then sent to the IRC channels if the mIRC client is installed. This is accomplished by the worm replacing the file SCRIPT.INI.
After a short delay the worm uses Microsoft Outlook to send copies of itself to all entries in the address book.
The mails will be of the same format as the original mail.
This worm also has another trick up it's sleeve in that it tries to download and install an executable file called WIN-BUGSFIX.EXE from the Internet. This exe file is a password stealing program that will email any cached passwords to the mail address MAILME@SUPER.NET.PH
In order to facilitate this download the worm sets the start-up page of Microsoft Internet Explorer to point to the web-page containing the password stealing trojan.
The email sent by this program is as follows :
-------------copy of email sent-----------
RAS Passwords:...[victim password info]
The password stealing trojan is also installed via the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\WIN-BUGSFIX
to autorun at system startup. After it has been run the password stealing trojan copies itself to WINDOWS\SYSTEM\WinFAT32.EXE and replaces the registry key with
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\
