We found an article that discusses the fact that the Fedora Project was hacked on 1/22. It seems that they aren't alone in the problem here of late. Both the Free Software Foundation and Proftpd have also recently been hacked into. To our knowledge no real damage has been done but it is a great reminder to change your passwords and make the tough. Also updating/changing SSH Keys also helps since the Fedora hack used the users SSH Key.
I found this article over on the Datamation Blog that lists 50 great opensource and freeware security solutions. maturity so be sure to do more research before replacing a key piece of your security infrastructure with them.
