If you are fine with some minor PHP development, then the easiest way is to 
tell MediaWiki how to handle the action "AttachFile". In MediaWiki, one can 
register a custom PHP function (hook) to deal with unknown actions, see [1]. 
This function could be written into LocalSettings.php and create a soft 
redirect to some actual file or proper MediaWiki aticle. MediaWiki's normal 
page processing can be stopped by returning "false" from the hook.
