The Foam Totem server was haxxored sometime in December. There was a user with a common name and an apparently weak password, which was used to get into the system via ssh (secure shell). I do not know how they got in further after that, but they were eventually able to log in as root.
There's no damage to any user data files as far as I can tell. There are traces of hacked OS and application stuff here and there: directories which shouldn't exist, a user added which shouldn't be there, baffling entries in the shell history, and so on. I have shut down everything naughty I have found and have shut off remote shell access (which is how they got in). (Sorry, Snuffy.)
I have backed up all user data to my personal computer just in case there's some kind of time bomb in there.
Anyway, the server will need to be wiped and rebuilt. I don't have the gumption to do it now; it's a full day of effort or so. Everything seems safe now, but after being compromised, nothing can be trusted forever. I'll get to it soon. I don't expect anyone will lose any data even if they add it from now on (like Popplers), but I wanted to give the warning.
