UK Businesses told to brace cyber defenses amid Iran conflict risk

**Executive summary:** The UK's National Cyber Security Centre advises UK organisations—particularly those with ties to the Middle East—to brace for likely indirect cyber threats as regional conflict escalates; it recommends checking internet-exposed assets, tightening access controls, subscribing to the NCSC Early Warning service, and reviewing guidance for critical infrastructure. The alert notes no current significant direct cyber threat from Iran to the UK but highlights past Iranian-aligned activity (disruption, wipers, influence operations) and warns that fast-moving events could increase targeting and nuisance or more serious intrusion attempts.
