The National Cyber Security Centre is urging UK organisations to take action amid evolving events in the Middle East.

While highlighting that there is no current significant change in the direct cyber threat from Iran to the UK, organisations are advised to review their cyber security posture.

As the conflict is fast moving, this assessment is subject to change and NSCS says that there is almost certainly a heightened risk of indirect cyber threat for those organisations and entities who have a presence, or supply chains, in the Middle East.

As a result, organisations should prepare to respond to the risk of collateral impacts in the UK from Iran-linked hacktivists by reading previously issued advisories on DDoS attacks, phishing activity and ICS Targeting.

Those who may be higher risk, for example with those with offices or supply chains in the region, should adjust their cyber security posture accordingly, by following NCSC's actions to take when threat is heightened guidance. 

Furthermore, CNI organisations may wish to pre-emptively review the NCSC's recently published guidance on actions to take now to prepare CNI organisations for severe cyber threat.
