I could, if it would really help. But one of the sites hasn't had a plugin added in many, many months. Webhostinghub said a number of their customers were hacked the same way.
They have tried cross checking all my plugins against all the other hacked sites on their server and they haven't found anything yet.
My sites are add ons to the main site. So the hack traveled down the directory structure to each website until it hit bottom.
If you still think a list would help, would supplying the plugins from the site with the fewest plugins do the job. It's at the bottom of the directory structure of websites.
