More Information
W32/CoiDung-A is a worm for the Windows platform.
When first run W32/CoiDung-A copies itself to:
<Windows>\dc.exe
<Windows>\help\Other.exe
<Windows>\inf\Other.exe
<Windows>\sviq.exe
<System>\Fun.exe
<System>\WinSit.exe
<System>\config\Win.exe
and creates the file <Windows>\wininit.ini.
The following registry entries are created to run dc.exe, Other.exe, sviq.exe, Fun.exe and Win.exe on startup:
HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows
run
<System>\config\Win.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run

HKCU\Software\Microsoft\Windows\CurrentVersion\Run

<System>\Fun.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
dc
<Windows>\dc.exe
HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows
load
<Windows>\inf\Other.exe
The following registry entry is changed to run WinSit.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell
Explorer.exe <System>\WinSit.exe
(the default value for this registry entry is "Explorer.exe" which causes the Microsoft file <Windows>\Explorer.exe to be run on startup).
