An ICS-capable malware and several regular disk wipers for Windows, Linux, and Solaris operating systems were used in the attack. The attack was targeted at a single private energy company with operations at a couple of locations. Had the attack been successfully executed, it would have impacted two million civilians in the region where the energy company supplies electricity. The main target in these attacks has been critical infrastructure, but this was the most “serious” and “sophisticated” attack of all.”]
