Type: Worm
Category : Win32

Win32/Conficker.C is a worm capable of blocking security related websites, terminating system security services and
downloading component files using time-based generated URLs.

When executed, Win32/Conficker.C drops a copy of itself using a random filename in the %System% directory. It may also
drop copies of itself in the following directories:

%Program Files%\Windows Media Player
%Program Files%\Internet Explorer
%Program Files%\Movie Maker

For these and other dropped files, Win32/Conficker.C:

* Sets Read Only, Hidden and System file attributes
* Generates a file creation/access time-stamp based on that of "kernel32.dll"
* Creates access control entries
* Exclusively locks the file, thus restricting access and privileges

Note: %System% and %Program Files% are variable locations. The malware determines the locations of these folders by
querying the operating system. The default installation location for the System directory for XP and Vista
is C:\Windows\System32. A typical location for the Program Files folder would be C:\Program Files.

In order to automatically execute at each startup, it adds the registry entry below:

= "rundll32.exe , "

Conficker also registers a service with a random name created by combining a word from this list:
