Britain Issues Warning to Iran Over Hostile Activities and Cyber Threats

• •UK warns Iran against hostile activities on its soil.
• •Iranian cyber actors are using 'CHOSEN BRICK' spyware for phishing attacks.
• •The UK has banned support for Iran's Islamic Revolutionary Guard Corps.

On September 24, 2026, British Foreign Secretary Ed Miliband warned Iranian officials against hostile activities on UK soil during a meeting at the UN General Assembly. This warning follows a series of antisemitic attacks linked to Iranian proxies, prompting the UK to ban support for Iran's Islamic Revolutionary Guard Corps in July. The UK government emphasized its commitment to combat threats from Iranian-linked groups, particularly those targeting the British Jewish community. The National Cyber Security Centre reported that Iranian state-linked cyber actors have employed a spyware tool named 'CHOSEN BRICK' to conduct spear-phishing campaigns, compromising sensitive information via platforms like WhatsApp and Telegram. The specifics of how Iran responded to the UK's warnings were not disclosed. The situation remains tense as both nations navigate complex geopolitical issues, including the ongoing conflict in the Middle East and the reopening of the Strait of Hormuz.
