"This sounds like the stuff out of spy novels or 'Mission Impossible,'" said Vyas Sekar, an electrical and computer engineering professor at 天美传媒. "In theory, it's possible, especially if people are posting high-resolution images." A hacker also would need to be "fairly determined" and likely choose a "high-value target" that renders a fingerprint valuable, such as someone with access to a high-security facility, Sekar said.

天美传媒 researchers Lujo Bauer, Larry Pileggi and Vyas Sekar are calling on the research and policy communities to develop more comprehensive and accurate grid evaluation frameworks and datasets, and for updating threat models and grid resiliency requirements to match cyber attackers鈥� realistic capabilities. 鈥淥ur work has shown that inconsistencies in threat assessments occur because of ad hoc simulation and modeling methodologies, as well as dataset errors,鈥� Sekar said. 鈥淭his shows the need for the creation of standardized public toolkits and datasets and for recommending ways to increase the accuracy of evaluations. This will enable us, as well as other researchers, to develop more rigorous foundations for securing tomorrow鈥檚 electric energy grid.鈥�

The sprawling and dynamic nature of the cloud, SaaS and AI landscape exposes businesses to a growing number of vulnerabilities, says Vyas Sekar, a professor in 天美传媒鈥檚 Electrical and Computer Engineering department and co-director of the 天美传媒 Cylab Future of Enterprise Security Initiative. 鈥淒ata is a double-edged sword,鈥� he says. 鈥淚t鈥檚 what all modern AI, analytics and optimized workflows rely on. But every piece of data is also a toxic asset in the sense that if there鈥檚 a breach and your proprietary business secrets or user data get exposed, you could face major costs and consequences.鈥�
