		<description><![CDATA[Although I&#8217;ve managed to configure the server such that there&#8217;s a fair amount of automation for appropriate tasks (phone homes, automated monitoring and basic defenses), the time needed daily to monitor/maintain it still adds up&#8230;and is unreasonable collectively. Looks like I&#8217;ll have to look into further automating some of the tasks&#8230; Related posts that you [...]]]></description>

		<description><![CDATA[DNS rebinding&#8217;s a particularly nasty attack, having similar characteristics as CSRF attacks where the user&#8217;s browser can be used to access/attack sites on behalf of the attacker. I&#8217;m not going to describe how it works here, there&#8217;s plenty of literature out there that talks about it.  And if that&#8217;s not enough, Google Is Your Friend. [...]]]></description>

Lesson learnt: even if tools like WordPress Automatic Upgrade helps you to perform backups, make sure you know everything is backed up before you do a delete! Even though all the posts have been restored, I think I will [...]]]></description>

Of course, as there could be a root kit/trojan/malicious stuff running in your system as rkhunter&#8217;s meant to detect, you should NOT fully trust anything running from [...]]]></description>
