directories in /home/admispconfig/ispconfig renamed?
Today I logged into my server as normal to run a few commands, and I discovered that the directories that reside within /home/admispconfig/ispconfig have been renamed to impossible names. The only two files in there are named "n" and "tempř?w?l". The interesting part is that neither one of them can be renamed (I'm assuming because of the question marks), and the file(directory?) "n" cannot be cat'ed either.
The first thing that entered my mind was perhaps the server was hacked, but after checking through the logs and running chkrootkit which I compiled myself right before I used, I am still clueless. Everything else appears to be in order as well.
The system is running Debian Sarge 3.1 and has ISPConfig 2.2.11 installed.
Any help would be appreciated.
