Your server is likely compromised now. You should have your ISP run a thorough check of the system for backdoors, rootkits, etc etc.

As Nico mentioned, your server may already have the RAR extension loaded, or the hackers may have previously uploaded files that allowed them to install the RAR extension without your knowledge.
