; (win32.Neo = win32.Miam for AVP)
|
|||
|
|
; I'm proud to present you my first real win32 virus.
|
|||
|
|
; It's not a fantastic virus but i am not old in the scene so don't blame me.
|
|||
|
|
; This virus uses per-process residency method in order to infect the files
|
|||
|
|
; that the user uses the most.
|
|||
|
|
;
|
|||
|
|
; When the virus starts the first time, it looks in kernel32, user32, advapi32 and
|
|||
|
|
; saves all the Apis adresses needed, then it infects all the current directory
|
|||
|
|
; and files in the windows directory.
|
|||
|
|
; The virus does not infect all the windows directory, it infects files like notepad.exe
|
|||
|
|
; and calc.exe because infecting all this directory is not very stealth (it is slow).
|
|||
|
|
; It infects the file Runonce.exe because this file is loaded before explorer.exe
|
|||
|
|
; and it can infect the explorer.
|
|||
|
|
; If it is the first generation, the virus displays a message.
|
|||
|
|
;
|
|||
|
|
; the virus increases last section when it infects a file.
|
|||
|
|
; It infects only PE files, and it makes all sections read/write/exec.
|
|||
|
|
; When the infected programm starts, the virus look in the Import Table
|
|||
|
|
; and try to hook CreateFileA.
|
|||
|
|
; When CreateFileA is hooked, the virus infect all the directory where the
|
|||
|
|
; opened file is located.
|
|||
|
|
; The infection mark is a little smiley in the file (i love that, it makes me
|
|||
|
|
; think of a real life ;)
|
|||
|
|
;
|
|||
|
|
; Payload: the virus drops a bitmap file in the c:\ directory, then
|
|||
|
|
; it changes screen background to black and shows the gfx "WAKE UP NEO" :p
|
|||
|
|
;
|
|||
|
|
; I saw many per-process resident virus, but they never change the Import Table
|
|||
|
|
; characteristics. And if the Import Table has not the flag write it will crash.
|
|||
|
|
; someone said me it was always writeable but look in notepad.exe for example,
|
|||
|
|
; it's not writeable.
|
|||
|
|
; the section which contain the import table has not always the same name, so this
|
|||
|
|
; virus changes all the sections characteristics to read/write/exec.
|
|||
|
|
; I'm sorry but all the comments are in french. ( it's difficult for me
|
|||
|
|
; to speak english )
|
|||
|
|
;
|
|||
|
|
; The virus erase few bytes of the first section of the executable with some code.
|
|||
|
|
; this code jump to the virus with a jmp. The erased code is saved before in a
|
|||
|
|
; buffer, and when the virus starts the original code is restored.
|
|||
|
|
; There is a SEH in the infection proc.
