Ever have to pentest a CMS and need to puzzle out what plugins and themes it has? Or ever see a cool site you know is running CMS-X but wonder what modules and themes they used? It can be tedious at best, or impossible at worst, to figure it out.

Read more about it over at Sunera's Security Blog (where I work), and while you're there grab the RSS feed as we'll be blogging over there & releasing a few more tools in the coming weeks!
