"Completely off-topic, but I thought you might want to see this and, perhaps, weigh in. Scary stuff."
Yes it is scary. And it has nothing to do with the virus itself. I'll tell you why it's scary.
Most, if not all, of the PLCs (Programmable Logic Controllers) that are on manufacturing lines or other industrial facilities have no security in them whatsoever. Modern plants use these programmable devices to control all aspects of manufacturing. They are miniature computers that you hook up to drives, motors, hell almost anything. You program the computer to perform a repetitive action, and you have an automated assembly line. To program these things, all you need is a telnet client (which every computer has). You connect to the PLC from that client and presto! you see all the result codes that PLC is measuring. No username, no password no nothing. Just by connecting, you're in. For instance, say you have a PLC that monitors and controls a motor. Just by making a telnet connection you see the RPMs of the motor scrolling on your screen. Randomly type some characters on your keyboard long enough, and you'll tell the motor to stop, slow down, speed up whatever. Given that most manufacturing lines run on very tight tolerances, any random changes will at least ruin the product or blow up the entire goddamned plant. And you can do it by just monkeying around on the keyboard.
Which is why it is a bad idea to connect these fucking disasters waiting to happen to a public network. To secure them, you have to use physical control measures. One computer per PLC within a "secured" facility (usually by a $7.50/hour security guard sleeping at his desk). So by hook or by crook you either insert a USB key with a program and take over the computer yourself, or you convince the engineer in charge of the line to do it. Bundle it with a "fix" for the PLC software and the hapless engineer will not know what happened.
My point is, it is childs play to take over a PLC and blow up a plant. And you thought Windows was full of security holes, it's frakkin' Fort Knox compared to a PLC. Good luck sleeping tonight!
