What are PLCs used for in supply chains?

Programmable logic controllers automate factory lines, from sorting robots to batch processing — core to efficient execution, but internet-exposed ones invite hacks like these Iranian ones.

How do I check if my Rockwell PLCs are targeted by Iranian actors?

Scan logs for ports 44818, 2222, 102, 502; hunt CISA's IOCs (IPs, file hashes); switch to RUN mode and call Rockwell/FBI if suspicious.

Will Iranian PLC attacks disrupt my entire supply chain?

Potentially — one factory halt ripples to logistics, inventory; energy/water hits amplify, but firewalls and segmentation cut 80% risk per agency recs.
