More Information

W32/SillyFDC-Y is a worm for the windows platform.

When run W32/SillyFDC-Y copies itself to

<Windows>\WinLogon.exe
<Program Files>\Windows NT\lsass.exe
<LocalService>\services.exe
<System>\Drivers\smss.exe

The following registry entry is created to run WinLogon.exe on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
WinLogon
<Windows>\WinLogon.exe

W32/SillyFDC-Y attempts to periodically copy itself to removeable drives, including floppy drives and USB keys. The worm will attempt to create a hidden file Autorun.inf on the removeable drive and copy itself to the following locations on the removeable drive:

Recycler.exe
<Random>.exe
service.exe
game.exe
Gwen(ISU) Scandal.exe
Sex Video.exe
Winlogon.exe
smss.exe

The file Autorun.inf is designed to start the Recycler.exe once the removeable drive is connected to a uninfected computer.
