This worm spreads via the Internet as an attachment to infected messages. It sends itself to email addresses harvested from the victim machine.

The worm is also able to download other files from the Internet without the user's knowledge or consent.

The worm itself is a Windows PE EXE file 95369 bytes in size.

Installation

Once launched, the worm causes an error message to be displayed in order to confuse the user.

When installing, the worm copies itself as hidn2.exe to the following directory:

%UserProfile%\Application Data\hidn\hidn2.exe

It also creates a file called m_hook.sys in the same directory.

The worm creates the following entry in the system registry:

[HKCU\Software\FirstRuxzx]
"FirstRun"="dword:00000001"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"drv_st_key"="%UserProfile%\Application Data\hidn\hidn2.exe"

The worm deletes the following registry key, making it impossible to boot the victim machine in safe mode::

[HKLM\System\CurrentControlSet\Control\SafeBoot]

It also creates the following files:

%SystemDrive%\error.gif
%SystemDrive%\temp.zip
