OPC-UA Cyber Threats Explained →
OPC-UA serves as a specification for data exchange and communication between an Engineer Workstation and Endpoints. For attackers aiming to target all devices using OPC-UA in a facility, the ideal scenario would be to execute a PITM (Plant in the Middle) attack. This enables hackers to monitor all OPC data transmissions within the plant, and also manipulate that transmitted data in a way that convinces the recipient of the attacker's altered data integrity. This insidious attack method means that it will take longer for the organization to detect that anything is amiss, giving it more time to carry out its destructive objectives.
