The smart grid, the emerging power distribution infrastructure upgrade, may not be the bright idea its name suggests. In the rush to modernize the way electricity moves, security appears to be an afterthought.
At Black Hat on Thursday, Mike Davis, a senior security consultant with IOActive, plans to conduct a worm attack on a smart meter, a part of the smart grid that's being installed at consumers' homes around the country.
The worm, Davis claims, can copy itself from one smart meter to the next in a neighborhood, ultimately causing power outages and rendering the smart meter inoperable.
"Many of the security vulnerabilities we found are pretty frightening and most smart meters don't even use encryption or ask for authentication before carrying out sensitive functions like running software updates and severing customers from the power grid," said Davis in a statement.
IOActive president and CEO Joshua Pennell said much the same thing in March when he testified before the Committee of Homeland Security and the Department of Homeland Security.
"Based on our research and the ability to easily introduce serious threats, IOActive believes that the relative security immaturity of the smart grid and AMI markets warrants the adoption of proven industry best practices including the requirement of independent third-party security assessments of all smart grid technologies that are being proposed for deployment in the nation's critical infrastructure," he said.
Last year, a CIA analyst revealed that "cyberattacks have been used to disrupt power equipment in several regions outside the United States." Such attacks have been rare due to the complexity and obscurity of the SCADA systems that govern electrical infrastructure. With the smart grid transition, the technical barriers to an attack of this sort are likely to be lower, at least initially.
Google and Microsoft are both developing smart meter services that aim to provide greater insight into home energy usage. Google has its PowerMeter project, and Microsoft in June introduced Hohm.
Davis is scheduled to make his presentation on Thursday, July 30 from 4:45-6:00 P.M. in the Milano Ballroom at Ceasar's Palace in Las Vegas, where Black Hat is being held.
