Considerations for Critical Infrastructure Operators Working With Third-Party ICS Integrators
US agencies warn critical infrastructure operators about third-party ICS integrator risks.
The FBI and CISA have issued a fact sheet highlighting risks for critical infrastructure entities working with third-party Industrial Control System (ICS) integrators. The agencies emphasize the importance of the principle of least privilege and secure practices to prevent malicious actors from exploiting third-party access. A recent incident involved foreign cyber actors gaining access to a US industrial automation company's network, exfiltrating sensitive SCADA and ICS data.

The lesson from this incident
Full lessonForeign cyber actors exploited trusted third-party access granted to an industrial automation company to infiltrate networks and exfiltrate sensitive SCADA and ICS data. The root failure lies in over-permissioned third-party accounts that lacked proper controls, monitoring, and least-privilege enforcement. This matters because ICS and SCADA systems underpin physical operations in critical infrastructure — a compromise can cascade from data theft to operational disruption or even physical harm. Organizations often extend implicit trust to integrators without validating their security posture, creating a backdoor that bypasses perimeter defenses entirely.
What helps against this
How we list vendors- Privileged access management (PAM)
Admin accounts stop being one stolen password away from control of everything.
- OT and industrial control system security
Factory, building and utility control systems get visibility and protection.
- Third-party risk management (TPRM)
You know which suppliers could hurt you, and you hear quickly when one of them is breached.
