When the worm is executed it creates a copy of itself as
"Documents and Settings\*username*\Application Data\hidn\hidn.exe"
It deletes the "SYSTEM\CurrentControlSet\Control\SafeBoot" entry from the registry
to prevent booting the computer into Safe Mode.
Drops the "m_hook.sys" file which helps hiding the worm in the memory from
numerous firewall and antivirus applications and also prevents the execution of
other system tools such as regedit.exe.

security related services:

On the first run the worm creates the "FirstRun"="1" entry in the
HKEY_CURRENT_USER\Software\Microsoft\FirstRuxzx registry key.
It drops and opens the file "C:\error.gif" which is a clean image file containing
the string "Error".
Creates a new thread which waits for 5 minutes then creates the
"drv_st_key"="C:\Documents and Settings\*usernév*\Application Data\hidn\hidn.exe"
entry in the "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run"
registry key. This key will provide an automated run of the worm on every system
start.
It Checks the availablity of an internet connection by connecting to
"smtp.google.com".
Creates a new thread which first deletes the "%System%\re_file.exe" file if it
exists then it attempts to download a binary with the same name from one of the
following urls:
