# Iranian Cyber Threats on the Rise: A Warning to UK Organizations

The United Kingdom's National Cyber Security Centre (NCSC) has issued a warning to British organizations of an increased risk of Iranian cyberattacks amid the ongoing conflict in the Middle East. While there is no direct threat from Iran to the UK, the NCSC advises organizations with a presence or supply chains in the region to be vigilant and prepared for potential attacks.

The NCSC's advisory highlights the continued threat posed by state-sponsored hacking groups in Iran, despite the current Internet blackout imposed by the Iranian regime. These groups are believed to maintain some capability to conduct cyber activity, posing a risk to targets in the Middle East and beyond. The warning comes as a follow-up to previous advisories from U.S. cyber agencies, which have also warned of escalating risks from Iranian-backed hacking groups.

To prepare for potential attacks, UK organizations are advised to review their external attack surface and increase monitoring. Those facing attacks targeting their supply chains or offices in the Middle East should prioritize strengthening their cybersecurity posture. The NCSC recommends that organizations follow previously released guidance on Distributed Denial-of-Service (DDoS) attacks, phishing activity, and Industrial Control Systems (ICS) Targeting.

In light of rapidly evolving events in the Middle East, it is crucial for UK organizations to remain alert to the potential risk of cyber compromise, particularly those with assets or supply chains in areas of regional tensions. Jonathon Ellison, NCSC Director for National Resilience, emphasizes the importance of proactive measures: "Organisations are strongly encouraged to act now, following the recommended actions to prioritise and strengthen their cyber security posture."

The Iranian cyber threat landscape is complex and constantly evolving. As one U.S. Department of Homeland Security advisory noted in June, escalating risks from Iran-backed hacking groups and pro-Iranian hacktivists due to unrest in the Middle East warrant close attention. A joint advisory issued by U.S. cyber agencies in October warned of Iranian-affiliated hackers targeting U.S. critical infrastructure.

In response to these concerns, it is essential for organizations to prioritize their cybersecurity posture and take proactive steps to mitigate potential risks. By following established guidelines and staying informed about emerging threats, UK organizations can reduce their exposure to the Iranian cyber threat.

### Background on the Iranian Cyber Threat

The Iranian cyber threat landscape is characterized by state-sponsored hacking groups that have demonstrated a willingness to engage in sophisticated cyberattacks against targets in the Middle East and beyond. These groups often employ tactics such as DDoS attacks, phishing, and ICS targeting to disrupt critical infrastructure and steal sensitive information.

### Measures to Mitigate the Risk

To mitigate the risk of Iranian cyberattacks, UK organizations should take the following steps:

1. Review their external attack surface and increase monitoring. 2. Follow established guidance on DDoS attacks, phishing activity, and ICS Targeting. 3. Prioritize strengthening their cybersecurity posture.

### Conclusion

The Iranian cyber threat landscape is complex and constantly evolving. As UK organizations continue to operate in a rapidly changing environment, it is essential that they prioritize their cybersecurity posture and take proactive steps to mitigate potential risks. By following established guidelines and staying informed about emerging threats, organizations can reduce their exposure to the Iranian cyber threat and protect themselves against potential attacks.
