Cyber worm shuts down 13 Auto plants in US

March 19, 2021


The Zotob worm 13 shuts down US auto plants. Despite having professionally installed firewalls separating the Internet, the company network and the control network, the Zotob worm had made its way into the control system (probably via a laptop). Once in the control system, it was able to travel from plant to plant in seconds. Approximately 50,000 assembly line workers had to cease work during the outages.
