Ballistic missiles struck targets across multiple Gulf states this weekend in retaliatory strikes following a coordinated military operation that included the largest cyber operation in recorded history. Gulf-wide airspace closures grounded major airlines, the US Navy declared a maritime warning zone across the Strait of Hormuz, and GPS jamming is disrupting nearly a thousand vessels per day. Behind the hacktivist DDoS claims now targeting Gulf organizations, a state-sponsored espionage campaign running since January is accelerating — abusing legitimate remote management tools for persistent access while OT-focused groups target water and energy infrastructure. This special edition delivers prioritized response actions from P0 through P2 drawn from a TLP:CLEAR joint advisory by CISA, FBI, NSA, and DC3.
