It now appears to repeat
each night in the same time slot and some if not many of the ip's are .kr.
I searched the posts in this and other lists before I put my original post
up and found nothing similar to what I'm seeing here. I'd like to think
that
any good admin in this list seeing a 1000 new error messages in their logs
would (again) question the security implications. Who knows what the next
exploit looks like until it happens.
I'd still like to hear a good theory as to this sudden burst of activity.
