There were a few things that I found disturbing, but in the wake of the whole Chinese State-sponsored hacking agenda, the findings were definitely suggestive, albeit with all the normal caveats of a small sample size.<p>"A total of 39 attacks were mounted on Wilhoit’s honeypots, some of which involved modifying the settings of the physical system they appeared to control. Attacks appeared to originate from computers in a variety of countries, with 35 percent from China, 19 percent from the U.S., and 12 percent from Laos."<p>"The most striking attacks exploited bugs to change the settings of Wilhoit’s imaginary industrial systems. “They were doing things that would change the water pressure, or temperature, or stop the flow on the water pump,” says Wilhoit."<p>"Because the attacks made use of techniques specific to industrial control systems, Wilhoit believes they were carried out by people intent on finding and messing with such systems."<p>The last of which, seems to be the most inflammatory. However, I'm unwilling to make the leap for one reason. As is oftentimes the case and rightfully so, they are sparse on details as to what the hack is and therefore, I can't determine what level of skill is required to target industrial control systems (though that's not my field anyway). Though I'd like to know more, b/c as stated, these systems often have little to no security and are connected to the web.
