Alert Overview

The United Kingdom’s National Cyber Security Centre (NCSC) alerted British organisations to a heightened risk of Iranian cyber‑attacks amid the ongoing conflict in the Middle East.

While there is no significant change in the direct cyber threat from Iran to the UK, the NCSC said this could change at any time, given how quickly the situation is developing. The warning was primarily issued for organisations and entities with a presence or supply chains in the Middle East.

Even though most of Iran is currently dealing with a widespread Internet blackout imposed by the Iranian regime, state‑sponsored hacking groups are likely still able to attack targets.

“Iranian state and Iran‑linked cyber actors almost certainly currently maintain at least some capability to conduct cyber activity,” the NCSC said.

Recommendations for UK organisations

• Prepare for potential DDoS attacks – follow previously released guidance on DDoS attacks.
• Guard against phishing – see the NCSC’s advice on phishing activity.
• Protect industrial control systems (ICS) – review the NCSC’s recommendations on ICS targeting.
• Review external attack surface – organisations facing attacks on supply chains or offices in the Middle East should review their external attack surface.
• Increase monitoring – enhance situational awareness by increasing monitoring of threats and network activity.

“In light of rapidly evolving events in the Middle East, it is critical that all UK organisations remain alert to the potential risk of cyber compromise, particularly those with assets or supply chains that are in areas of regional tensions,” Jonathon Ellison, NCSC Director for National Resilience, told BleepingComputer in an emailed statement.
“Organisations are strongly encouraged to act now, following the recommended actions to prioritise and strengthen their cyber security posture.”
