On my server it shows “Possible rootkits: 0” so there are no rootkits on the server. I received the above email because there is two suspect applications on my server (Suspect applications: 2).
The rkhunter logs shows openssl and httpd application was out-of-date and that is the reason why I got rkhunter warning from the server. Updating the applications to latest version will fix the rkhunter warning.
