Because of many recent attacks on my machines in the last few months, I built a new machine using a processor with a No-Execute bit. I put all my sites on there with Apache 2.0.54 and patched everything to date. I only allow port 80, 443, ftp and ssh to reach the machine. There is only one user on the machine, me. The FTP authentication is handled by an NcFTPd internal database. The other day, my machine was flooding the network and nothing worked. I checked top and there was a perl script called leet.pl running. I did a find and there were several perl scripts owned by user apache in my /tmp. They all seemed to be connect-back scripts. I'm no expert on security, but it seems odd to me that a remote user could use apache to write to my /tmp directory and then execute the script. Any idea how this happened? How do I prevent it in the future? How do I sterilize my machine? Thanks for the help.
