To further the explanation, the patch level on the OS was SP2. I've not
yet poked into IIS's patch revisions, or SQL's.

It's a long story, but this was a third party box that got mangled, and I
got to dissect it.

As for anonymous writeable ftp, I don't know. IIS had three definitions to
allow ftp, one of which did not allow anonymous writes, one of which did,
and one of which was user/pass restricted. Figuring out what was running
has proven difficult, as before the client realised that things were far
out of control, they tried fixing some things on their own.

I'll probably look at it again tomorrow and see what can be ascertained.

Yes, the box had a pretty trivial admin password. The client didn't change
our shipped default.

Yes, it had default.ida executeable. (bleh).

I'm truly leaning towards it having been hit more than once.
