Following Russia’s full-scale invasion of Ukraine, the Ukrainian power grid has come under sustained attack by Russian forces, and keeping it up and running has been a significant challenge. One of the major issues Ukrainian energy officials have had to confront is the way in which Russian electronic warfare systems have disrupted GPS, which is a key tool in running electrical distribution systems. Taras Vasyliv, the head of the Dispatching Control Systems Department at the Ukrainian energy utility Ukrenergo, and Joe Marshall, a security researcher at Cisco, collaborated on an innovative solution to address the vulnerabilities of GPS systems in the Ukrainian grid. And on this episode of Safe Mode, they sit down with host Elias Groll to discuss the novel tool they developed to maintain the delivery of electricity even in the face of Russian jamming.
