All achives that use eFiction as an automated archive, please be warned that a Russian hacker is specifically targeting your sites.
According to estepheia, the hacker in question registers on your site as an author called Shader (although this is subject to change, I'm sure) and then uploads a Trojan virus that completely kills the archive.
For more details, read this post.
Authors take note of this: you might be getting frantic emails from the owners of killed archives.
ALERT FOR whiskyinmind: This shader dude is on I Need A Parrot and he joined about the same time as the other targeted archives. If there is anyone in Mara's neck of the woods, let her know her site may have a problem.
