Pendahuluan
Virus
komputer merupakan program komputer yang dapat menggandakan atau
menyalin dirinya sendiri dan menyebar dengan cara menyisipkan salinan
dirinya ke dalam program atau dokumen lain. Virus komputer dapat
dianalogikan dengan virus biologis yang menyebar dengan cara menyisipkan
dirinya sendiri ke sel makhluk hidup. Virus komputer dapat merusak
(misalnya dengan merusak data pada dokumen), membuat pengguna komputer
merasa terganggu, maupun tidak menimbulkan efek sama sekali.
Cara Kerja
Virus komputer umumnya dapat merusak perangkat lunak komputer dan tidak
dapat secara langsung merusak perangkat keras komputer tetapi dapat
mengakibatkan kerusakan dengan cara memuat program yang memaksa over
process ke perangkat tertentu. Efek negatif virus komputer adalah
memperbanyak dirinya sendiri, yang membuat sumber daya pada komputer
(seperti penggunaan memori) menjadi berkurang secara signifikan. Hampir
95% virus komputer berbasis sistem operasi Windows. Sisanya menyerang
Linux/GNU, Mac, FreeBSD, OS/2 IBM, dan Sun Operating System. Virus yang
ganas akan merusak perangkat keras.
Kali ini saya akan membahas mengenai virus macro… (para virus maker diharap untuk tenang dulu!).
Pasti banyak bertanya kenapa kali ini membahas tentang cara membuat virus? Biasanya kan lebih sering membahas analisis virus atau antivirusnya itu….
Yah kali ini memang agak berbeda. Selain untuk mencari suasana baru, aku juga agak tertantang dengan artikel yang saya buat ini.
Sebelum aku membuat artikel ini, aku sengaja mencari-cari kelemahan dari antivirusku sendiri (baca:Morphost). Ternyata aku lebih tertarik untuk membuat virus macro untuk mencari celah antivirusku itu. Untuk membuat artikel ini memang butuh pengorbanan juga. Soalnya komputerku jadi terinfeksi oleh virusku sendiri. Haaahhh…..
Virus macro merupakan virus yang dibuat dalam bahasa pemrograman visual basic macro di Microsoft Office. Kita ambil contoh, virus macro Word.
CARA MEMBUAT VIRUS
- Buka Ms.Word (hanya contoh)
- buka tools > Macro> Visual Basic Editor
- Akan muncul gambar di bawah
Lalu kita ketikkan source virus nya pada kotak putih diatas dan akan tampak gambar seperti dibawah ini.
Sekarang muncul pertanyaan! Source yang bagaimana yang harus diketik???
Tenang, aku dah siapkan kok sourcenya. Makan neh source code!

EFEK-EFEK KECIL DAN TANDA-TANDA TERINFEKSI
Nah coba tebak mana file virus dan mana file yang bukan virus!!!!!!!!
Jawabannya lihat di bawah!!
CARA MEMBUAT VIRUS LANJUTAN
Ini nih, dulu saya udah janji untuk ngelanjutin sample virus macro yang saya buat dulu. Di tutorial kali ini saya akan jelasin sedikit demi sedikit untuk mempelajari virus macro ini…
Pernah dengar virus Macroid? Itu adalah salah satu contoh virus macro yang saya buat.
Langsung aja.
Buka visual Basic editor di Tools>macro>visual basic editor ato tekan pada keyboard Alt+F11
Tampilannya mirip dengan VB6 kita, dan penggunaan sourcenya juga gak jauh beda…
Misalnya :
Dim AD as object
Ya gak. Mirip kan dengan script di VB6? Dan dilanjutkan dengan penggunaan ”set”. Misalnya :
set AD=ActiveDocument.VBProject.VBComponents.Item(1)
ha ha ha… oke deh gak usah main-main. Langsung keserius nya aja…
Script dibawah ini untuk mengubah ”Name” document yang diinfeksi (umumnya ini yang dijadikan sebagai nama virus macro kita)
1
|
<span style="color: #ff0000;">dim AD as object set AD=ActiveDocument.VBProject.VBComponents.Item(1)</span>
|
1
|
<span style="color: #ff0000;">if AD.Name “Macroid” then AD.CodeModule.DeleteLines 1, AD.CodeModule.CountOfLines AD.Name = “Macroid” end if</span>
|
Script diatas bisa kamu sisipkan di ”Document_Close()” ato di ”Document_Open()” ato di ”Document_New()”
Kalo disisipkan di “Document_Close()” efeknya akan berjalan saat document ditutup. Dan begitu juga dengan “Document_Open()” dan “Document_new()”
Kalo disisipkan di “Document_Open()” efeknya akan berjalan saat document dibuka.
Kalo disisipkan di “Document_new()” efeknya akan aberjalan saat document baru dibuka.
Ini contoh gambarnya…
Efeknya adalah ini.
Itu tandanya virus “Macroid”!!! ha ha ha… oke.
Sebenarnya saya mau menjelaskan lebih banyak soal trik-trik virus macro, tapi saya yakin sebelum sampai diatas pasti masih banyak masalah untuk kalian…
Sebelumnya kalian harus perhatikan security macro kalian.
Lihat Tools>Macro>security
Yang harus kita pilih adalah opsi ”Low” supaya Ms.Word akan menjalankan semua script di visual Basic Editor. Karena kita masih belajar-belajar biarkan saja kita yang atur security ini, nanti kalo kita udah mau bikin virus macro, ada caranya supaya virus kita yang ngatur security ini… tenang aja…
Setelah kita set securitynya, silakan save document terus hidupkan document kita tadi.
Ada satu lagi masalah… kalo nanti ”misalnya” ada gambar seperti dibawah ini:
Berarti ada hal yang harus kita atur dulu… Buka lagi security macro tadi.
Lalu pada tab Trusted Publishers silakan ceklis “Trust aceess to Visual Basic Project”
Nah klo itu dah dilakukan, maka untuk berikut-berikutnya kalo kita mau ngetes virus macro kita udah bisa boss….
