Stuxnet worm hits industrial PLC systems:
SO, if you use Siemens PLCs connected to PCs in an industrial setup, this may concern you.
It creates an extremely dangerous situation, long predicted to happen of course, but here now.
Anybody who uses Windows for industrial control is crazy. If they also connect it to the Internet, they are criminal as well.
Given the outrageous state of current OSs, mission-critical systems shouldn't be connected to the internet at all. One could use a throw-away computer to connect to the internet, and let that talk to the control machine through, say, a serial link that is absolutely wormproof.

course,
There's the little uc-based bone-simple web servers. Those ought to be fairly safe because they do not really use an OS.

Yeah, things like the Lantronix ethernet-to-serial bricks.

Germany based, but used all over the world. Zillions of factories and industrial complexes, chemical plants, etc, use Siemens PLCs. Often connected to a PC. It is sort of a standard. I have worked with those, cannot imagine what could not blow up if some pump or valve was programmed wrong.

Siemens PLCs.
Old rule, and the SCADA stuff I used emphasized that over and over again in the manuals: Never, ever, rely on the computer when it comes to handling potentially critical conditions. There has to be some real hardware as protection. Like a pressure switch and a relay. Always.

If you had any brains, you would also be aware of the way such systems are constructed.
Damn! Where is the switch to throw that causes all the stupid dolts in the world to "blow up"?
The world should begin taking Soylent Green volunteers. The sharks surrounding the New Devil's Island need occasional feeding to keep them interested in surrounding the prison, waiting for fresh meat to enter the water.

Do you actually know the difference between a PLC and a PC?
course,
From the article: "Called Stuxnet, the worm was discovered in July when researchers at VirusBlokAda found it on computers in Iran."
Sounds like the US is trying what the Chinese were trying.
Couldn't happen in a better place.

ePresumptuous fucktard.
Windows isn't directly in the control loop here -- it's the PLCs that are doing the actual industrial control, and then (Siemens') software on a Windows box is just configuring the PLCs, collecting data, etc.
Do you? Or for that matter that there are PC based PLCs? I recently repaired a pipe bender controlled by a Yaskawa F7 which is programmed to control the machine. As usual, it was screwed up by the wire pullers who didn't pay attention to what they were doing. They installed a 240 V outlet, and wired the other end for 120 V. In addition to correcting the wiring, I added a boost transformer to raise the 208 to 245 volts. It works better than it ever did at the previous location.

So, it's another fine example of 'European engineering'?

Nothing to do with that, it is a virus that comes into the US made Microsoft PC, and from there reconfigures the PLC. So it is all YOUR fault obviously. :-)

PC,
Bullshit. I NEVER connect machine controls to the outside world, other than to the AC power grid. Connecting a tol to the internet is something done by losers.

In your pants.
Apart from the fact that that grid has been hacked too in the US, the article mentions that thing came in via USB sticks. Try reading it.
PS I did a realy big industrial thing, with PC as user interface. We went there one day to put in some new software, and when we [unexpectedly] entered the control room they were playing some game on that PC. How did it get on there? hehe
