An analysis by Claroty s newly branded Team82 research team found striking vulnerabilities in the CODESYS and WAGO industrial systems. The vulnerabilities, if exploited, can lead to serious consequences, including gaining control of industrial equipment and operations. An attacker could stop a PLC program responsible for temperature regulation of the production line, or change centrifuge speeds as was the case with Stuxnet. These types of attacks could lead to real-life damage and affect production times and availability.
