• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Catalinx hack

Regular Pleskian
I recently noticed some strange email bounces coming back to my Plesk "test" server. It turns out that the server was hacked. After som investigation I found this site that explains what was compromised...

http://catalinx.org

Here is what it says...

--snip--
NOTICE, THIS DOMAIN WAS USED BY HACKERS FOR ROOTKIT EMAILS,
CHECK /etc/cron.daily/dnsquery,
/etc/cron.daily/distwatch,
/etc/init.d/killd,
/usr/lib/popauth,
/usr/share/misc/blah/ and
your local smtp server for emails to [email protected] or [email protected]


You can check your Linux server for rootkits with any or all of these programs: chkrootkit, rkhunter, unhide.
This Website is NOT RELATED with the hackers.

What are some best practices for preventing such an attack in the future?
