“Interesting that it appears designed to specifically attack Siemens SCADA systems. This was no accident.”

I also read something earlier that the worm attacked PLC (Programmable Logic Controller) programs. Don't know if you're familiar with PLCs. They probably control 90% of automated systems, worldwide. Of course, Siemens is one of many manufacturers of PLCs.

Lots a speculation...

I’m quite familiar with PLCs; my employer makes some.
