SCADA, also known as Supervisory control and data acquisition is unfortunately used with critical infrastructure, like power grids. So, how do you shut down a power grid?

We will give you one horribly insecure example where a country connected their electric grid to the internet. Their admin backend where you can shutdown the power of different sections of the country, was exposed through Google cache, which let anyone have the ability  to shutdown their power.

 

Now why didn’t researchers of this country discover this? Because they threaten to kill anyone who they deem to have hacked their site that lives in their country, however their threat model did not account in that the rest of the world may discover their electric grid issues.

In our mind  this is so insecure it isn’t a hack, because if Google can access it and you access it on Google’s property, then you’re accessing it on Google’s servers, rather than hacking the companies servers.

 

How do you avoid this highly insecure setup?

Well, first if you have anything sensitive, do not connect it to the internet. Secondly, do not have SCADA online, for crying out loud. If you want to be hacked, then sure by all means go ahead, but this was so insecure you should never do this.

This is one very simple, glaring issue of how a system used for critical infrastructure can be used the way it was designed to shut it down, yet they didn’t consider they were designing it for others to use when they made it.

 

We will be writing more on SCADA in the near future.

 

 

 

The WordPress Plugin WP-doctor contains a trojan,  in the malware.txt file. A user  made this public over a year ago, yet nothing happened. So, we  reviewed it and they were right, so we contacted WordPress.

 

WordPress agreed that the trojan was in the software, however they could not find a point in the software where the trojan was being used. y  So, in other words the software was shipped with malicous code, but they weren’t using the malicious code, or rather no one has  yet to identify where that malicious code would work.

The WordPress team shut down the plugin while they talk to the team behind WP-Doctor to see if this was left over as part of an attempt in detecting malware, or if there is any legitimate reason for this WordPress Plugin to contain freaking malware.

Vulnerabilites are common in WordPress, malware shouldn’t be on WordPress or on any site as a useful program, yet this program at least has the trojan code in it. If it ever did anything is another question. At this point in time, we would advise you remove WP-doctor.
