[ISN] Hacking Critical Infrastructure: A How-To Guide

http://www.defenseone.com/technology/2015/07/hack-critical-infrastructure/118756/ By Patrick Tucker Defense One July 31, 2015 Cyber-aided physical attacks on power plants and the like are a growing concern. A pair of experts is set to reveal how to pull them off — and how to defend against them. How easy would it be to pull off a catastrophic cyber attack on, say, a nuclear power plant? At next week’s Black Hat and Def Con cybersecurity conferences, two security consultants will describe how bits might be used to disrupt physical infrastructure. U.S. Cyber Command officials say this is the threat that most deeply concerns them, according to a recent Government Accountability Office report. “This is because a cyber-physical incident could result in a loss of utility service or the catastrophic destruction of utility infrastructure, such as an explosion,” the report said. The most famous such attack is the 2010 Stuxnet worm, which damaged centrifuges at Iran’s Natanz nuclear enrichment plant. (It’s never been positively attributed to anyone, but common suspicion holds that it was the United States, possibly with Israel.) Scheduled to speak at the Las Vegas conferences are Jason Larsen, a principal security consultant with the firm IOActive, and Marina Krotofil, a security consultant at the European Network for Cyber Security. Larsen and Krotofil didn’t necessarily hack power plants to prove the exploits work; instead Krotofil has developed a model that can be used to simulate power plant attacks. It’s so credible that NIST uses it to find weakness in systems. […]
