‘Stuxnet’ Worm Far More Sophisticated Than Previously Thought — Krebs on Security

‘Stuxnet’ Worm Far More Sophisticated Than Previously Thought — Krebs on Security.

Brian Krebs has a detailed article on Stuxnet with details about its targeting Siemens industrial control systems.

“The mechanism [the Stuxnet worm] used to install the Siemens payload came at the very end, which means this isn’t a Siemens problem and that they could have substituted [General Electric], Rockwell or any other PLCs as the target system,” Weiss said. “At least one aspect of what Stuxnet does is to take control of the process and to be able to do…whatever the author or programmer wants it to do. That may be opening or closing a plant valve, turning a pump on or off, or speeding up a motor or slowing one down. This has potentially devastating consequences, and there needs to be a lot more attention focused on it.”
