 This virus can destroy the core production control computer software used by chemical, power generation and power transmission companies in various countries around the world, and instead "issue orders" to other computers in the factory.They can also use multiple vulnerabilities in Windows systems and Siemens SIMATICWinCC systems to attack.Although these systems operate independently from the network, if the operator inserts a virus-infected U disk into the system's USB interface, the virus will be able to gain control of the system without any other operational requirements or prompts.
