Sophisticated Malware Exploits Zero-Day Vulnerability, Targets Industrial Systems

By JDavis | 7/28/10 12:59 PM

We've previously posted (here and here) about the ongoing concern among experts surrounding the security of the critical infrastructure and the smart grid. These concerns have been made all the more important with the recent discovery of a sophisticated virus targeting computers that run certain industrial control systems -- potentially used to operate the critical infrastructure. As reported in Computerworld and BusinessWeek, the worm--known as "Stuxnet"--specifically targets Siemens industrial management systems.
