Global Threat Landscape

• US strikes tanker skirting the blockade; naval scope widens [corroborated]
  US forces struck an oil tanker near Iran's main export terminal, deep inside the Persian Gulf. It is the first strike on a commercial vessel attempting to run the blockade, and it signals that maritime enforcement now extends beyond military targets. Overnight strikes also hit Iranian command centres and missile sites on a sixth consecutive day of exchanges. Shipping operators should treat sanctioned-cargo routing anywhere in the Gulf as a kinetic risk, not merely a compliance one.
• Kuwait intercepts 32 drones; Iran hits US bases in Kuwait and Jordan [corroborated]
  Iranian retaliatory strikes targeted US military bases in Kuwait and Jordan, with Kuwait's Defence Ministry reporting 32 drones intercepted since dawn and warning residents of debris from air-defence engagements. The volume confirms Iran retains deep one-way-attack drone inventories despite a week of degradation strikes. Organisations near military installations in Kuwait, Jordan, and Bahrain should treat air-defence debris and interception overpressure as a primary duty-of-care exposure. Relevant capability: hostile-environment safety planning and close protection deployment.
• Hormuz transits collapse to three in 24 hours [corroborated]
  Open-source tracking recorded just three transits in the past 24 hours (two inbound, one outbound), against a pre-war daily average near 110. Whatever the declaratory status, commercial deterrence is now near-total. European energy planners should lock in alternative-supply contracts and treat Gulf routing as unavailable for unescorted traffic until further notice.

NATO & Allied Sphere

• US equipment reductions from NATO crisis plans confirmed [corroborated]
  Alliance planning sources confirm that fighters, bombers and submarines have been cut from NATO crisis plans. The rotation of a 4,000-strong armoured brigade combat team and a long-range fires battalion has also been cancelled. European staffs are re-baselining regional defence plans around reduced US enablers. That accelerates the capability-substitution programmes announced at Ankara and widens the role of vetted private-sector capability in national preparedness frameworks.
• European spending response: five Allies past 3.5% core target [corroborated]
  Lithuania, Estonia, Latvia, Poland, and Greece will exceed the 3.5% core-defence spending target this year, with European Allies and Canada trending toward roughly $634 billion in 2026 outlays. For the security sector, the near-term effect is procurement acceleration in exactly the domains the Ankara summit prioritised: CBRN preparedness, counter-UAS, infrastructure protection, and secure communications.
• NL CBRN vendor assessment: documentation phase
  The Dutch Ministry of Defence CBRN cluster assessment framework, published this week, moves qualifying vendors into the documentation phase. That phase covers curriculum standards, training infrastructure and supply-chain vetting evidence. Providers that intend to qualify should have their evidence packages assembled this quarter. Mission Support's four-level CBRN curriculum is structured by level, so each level can be checked against the published criteria.

Critical Infrastructure & Cyber

• NCSC-NL detects active Citrix NetScaler zero-day exploitation [corroborated]
  NCSC-NL detected active exploitation of a zero-day vulnerability in Citrix NetScaler appliances at multiple Dutch critical organisations, and issued confidential alerts to the affected entities. NetScaler appliances sit at the identity and remote-access boundary of the very organisations already under Sandworm reconnaissance pressure. That gives attackers a second, concurrent access vector into the Dutch critical-infrastructure target set. Organisations running NetScaler should apply emergency mitigations immediately and start a compromise assessment without waiting for confirmation that they were targeted. Relevant capability: cybersecurity assessment and incident response.
• Poland grid attack formally attributed to Russian intelligence [corroborated]
  The EU and UK formally attributed the cyberattack on Poland's power grid to Russian state actors. It is the bloc's most direct public attribution of a critical-infrastructure attack this year. Formal attribution unlocks coordinated response mechanisms, but it also widens the retaliation surface for European operators. Energy-sector security teams should assume that attribution announcements are followed by waves of opportunistic probing against peer operators.
• Water-management posture: no de-escalation signal
  The Sandworm campaign against Dutch waterboard SCADA systems remains active, and the affected authorities have not signalled that remediation is complete. This week's elevated measures were an IT/OT segmentation review, MFA enforcement on HMI access and a remote-access policy audit. They should be treated as the new baseline, not a temporary surge. Physical reviews of SCADA-adjacent sites remain warranted: physical security assessment.
