One thing that we see fairly frequently with Internet security companies is that they try to sell their largely unneeded, and usually largely ineffective, security products and services by portraying websites as under constant threat from sophisticated hackers. The reality is that while few hackers are quite sophisticated, most hackers only have rudimentary skills and basic security measures will prevent your website from being hacked. As an example of what you are dealing with in most cases let’s take a look at someone’s claim on ZONE-H – a website for displaying defaced websites – that they had hacked our website last week. Since that page is supposed to be removed once the claimed defacement is reviewed, here is a screenshot of it:
What you can see with that is that the mirror copy of our website shown from the time of the claimed defacement doesn’t actually show that the website has been hacked. Instead it shows that if you request a page on our website that doesn’t exist you will get a message that it doesn’t exist. Why someone would try to pass that off as defaced/hacked website is unclear to us.
Based on the URL of the supposed defaced page, http://www.whitefirdesign.com/wp-admin/admin-ajax.php?action=revslider_ajax_action&client_action=get_captions_css, what they were trying to exploit was a vulnerability in a WordPress plugin that a) we don’t even use, so there is no chance it could be exploited and b) if we did use it and had the vulnerable outdated version installed they would have needed to try to exploit it from where WordPress is actually installed on our website, which isn’t the root directory of the website as they tried (this could be easily checked on, which again shows the lack of sophistication that usually exists).
