What are the cybersecurity threats across the manufacturing sector?
Specific examples of advanced cybersecurity manufacturing threats include:
- Multi-stage spear phishing exploits that obtain access to the organization’s IT infrastructure before pivoting to the OT network.
- Exploits that connect to internet-accessible PLCs without providing authentication credentials for initial access.
- Using commonly used ports and standard application-layer protocols to communicate with controllers and download modified control logic.
- Modifying PLC control logic and parameters.
These threat trends are the fruits of greater IT-OT connectivity in the digital transformation process. Integrating IT and OT systems provides more efficient production processes but exposes manufacturing operations to new risks.
