This is a kind of alarmist paragraph though - the malware probably isn't intended to primarily or specifically kill or harm people. If it's from a state it's probably intended to shut down industrial processing. That might require doing something that causes harm, but that's not certain and it's probably not the goal. Other malware like Stux', and all the various intrusions into power infrastructure etc. that are always being talked about in the media, all share that same purpose - shutting down the logistical or productive capacity of a country, either in a very specific area like Israel v Iran re Nuclear or in a wider sense, like turning off the electricity.
