Was Stuxnet Worm Built to Attack Iran's Nuclear Program?

(1/3) > >>

mouser:
Fascinating stuff..

A highly sophisticated computer worm [Stuxnet] that has spread through Iran, Indonesia and India was built to destroy operations at one target: possibly Iran's Bushehr nuclear reactor....
Experts had first thought that Stuxnet was written to steal industrial secrets -- factory formulas that could be used to build counterfeit products. But Langner found something quite different. The worm actually looks for very specific Siemens settings -- a kind of fingerprint that tells it that it has been installed on a very specific Programmable Logic Controller (PLC) device -- and then it injects its own code into that system. Because of the complexity of the attack, the target "must be of extremely high value to the attacker," Langner wrote in his analysis.

Deozaan:
Really interesting prospect.

f0dder:
Yay for having SCADA stuff available over the internet - f'ing brilliant idea >_<

Deozaan:
It wouldn't necessarily have to be directly connected to the internet to get infected.

Someone could bring in a USB drive that was infected and connect it to a PC on the intranet which infects it.

I'm making this up as I go along so I'm probably wrong but it makes sense to me.  :D

f0dder:
True, Deo - but that's also pretty bad - (critical) SCADA systems really shouldn't be accessible from the outside by any means... they should have "air firewalling" :)

Btw, this is a worm, so either the systems *are* directly accessible from the 'net, or it uses other exploits to get into LANs and then start looking.
