**Persian Gulf risk is shifting not through constant vessel attacks, but through a decentralised posture, infrastructure pressure, and fast-moving uncertainty in the Strait of Hormuz.**

This week’s Maritime Intelligence Brief assesses how Iran’s IRGC “Mosaic Defence” doctrine changes the operational picture: authority is distributed across semi-autonomous provincial commands, enabling local units to execute asymmetric missions even when central leadership and infrastructure are degraded.

Alongside the Gulf update, this edition highlights a live cyber risk for ship operators: newly disclosed high-severity vulnerabilities affecting NAVTOR’s NavBox operational data gateway a reminder that satellite-connected shipboard OT systems remain a high-value target surface.

 

### **What this means for maritime operators**

- **Threat dynamics are less predictable:** decentralised command can increase variability in tactics and tempo.
- **Risk is not just at sea:** infrastructure pressure and regional disruption can quickly reshape port access, routing decisions, and contingency planning.
- **Cyber and physical risk are converging:** shipboard OT gateways and satellite links remain attractive points of exploitation.
