MI5 has warned that Ireland breaking news audiences and security officials across Europe should pay close attention to a rapidly changing threat landscape involving foreign states, artificial intelligence and extremist violence. The intelligence service says state-backed activity has expanded sharply in recent years, while AI is giving attackers new ways to spread propaganda, conduct reconnaissance and potentially develop dangerous weapons.
Speaking at his annual address in London, MI5 Director General Sir Ken McCallum said the service is now committing more resources to countering state threats than it did during the Cold War. He described Russia as the leading aggressor and warned that Iran-linked activity in the UK is also growing.
MI5 warns of expanding state threats
According to the intelligence chief, foreign threats have quadrupled over the past decade. Russia is accused of using hybrid warfare, a broad term covering cyber-attacks, sabotage, disinformation and activity carried out through intermediaries rather than conventional military forces.
MI5 believes the expulsion of almost 1,000 Russian intelligence officers and associated personnel since Russia’s invasion of Ukraine has weakened Moscow’s traditional covert network. However, the service says the Kremlin has increasingly turned to criminal groups and other proxies to carry out operations.
The warning comes amid wider concern among European governments that Russia could test the resolve of countries supporting Ukraine. The intelligence service said Russia had not moved into direct conventional conflict with NATO, but was seeking to create instability and pressure through less visible methods.
What is hybrid warfare?
- Cyber-attacks against public or private infrastructure
- Sabotage and covert disruption
- Online influence campaigns and misinformation
- Criminal proxies acting on behalf of foreign states
Artificial intelligence raises new security concerns
AI was a central theme of the address. Sir Ken said the technology is intensifying the contest between cyber attackers and defenders, while extremist groups are already exploring ways to use AI in planning and operations.
MI5 has identified attempts to use AI to improve reconnaissance and attack methods, including the development of AI-assisted drones. The service is also concerned that generative AI could produce highly personalised propaganda and radicalising content aimed at individuals or specific communities.
The most serious long-term concern involves bioweapons. Sir Ken said the danger had not yet materialised, but warned that AI could eventually lower barriers to understanding or developing biological threats. To assess these risks, MI5 has launched an AI Threat Assessment Centre to distinguish credible dangers from exaggerated claims.
Iran-linked activity and UK security
Iran was also identified as a growing source of hybrid activity. MI5 said there had been 50 arrests during the previous year linked to Iran-related operations. The alleged targets included Jewish communities and sensitive military locations.
The intelligence chief referred to concerns surrounding activity near RAF Fairford, where seven people were arrested and later bailed following reports involving suspicious vehicles. He said the incident was not isolated and that Iranian interest had been detected beyond that particular location.
The UK’s National Security Act, introduced in 2023, is being used to address individuals working on behalf of foreign powers. MI5 said the legislation has been applied to threats associated with Russia, Iran and China.

Extremist terrorism remains a major concern
MI5 said counter-terrorism work and efforts against state threats are now operating on a broadly comparable scale, representing a major change from previous years. The UK terrorism threat level was raised to severe in April, meaning an attack is considered highly likely.
Islamist terrorist organisations continue to inspire and direct attacks, but officials highlighted the growth of extreme right-wing terrorism. The service said online anti-immigration and anti-Muslim grievances were increasingly tipping into terrorist intent.
One particularly concerning trend is the young age of some people involved in extremist investigations. Sir Ken said MI5 had recently investigated a radicalised 13-year-old in the UK. Information from that case helped an international partner prevent a potentially lethal attack.
Why online radicalisation matters
Extremist networks can now reach vulnerable people directly through encrypted messaging services, social media platforms and algorithm-driven content. AI may make that process more effective by creating tailored material in different languages and styles.
For communities across Ireland, developments in UK security policy are relevant because threats involving online radicalisation, cybercrime and foreign interference do not stop at national borders. They may also become part of wider Irish politics news, Garda cooperation and European security discussions.

Foreign interference and democratic debate
Asked about claims that Russia interfered in the Brexit referendum, Sir Ken acknowledged that Moscow-linked media outlets, internet trolls and bot farms had attempted to influence public discussion. However, he distinguished between interference being attempted and an election or referendum result being changed.
He also cautioned against exaggerating the power of such campaigns, saying that portraying online influence networks as overwhelmingly powerful could play into the hands of adversaries. The comments underline the challenge facing governments: protecting democratic debate without amplifying hostile messaging.
What happens next?
MI5, GCHQ, MI6 and the UK’s AI Security Institute are working together to evaluate emerging threats. Their priorities include hostile-state activity, cyber operations, extremist content, drone technology and the possible misuse of AI in biological research.
The warning also highlights the importance of resilience. Governments, technology companies, schools and the public all have a role in identifying manipulation, reporting suspicious activity and improving digital security.
For readers following latest Irish news, the key takeaway is that international security is increasingly shaped by technology. Russia-linked operations, Iran-related activity and AI-enabled extremism are not separate risks; they are overlapping challenges that can affect public safety, democratic institutions and communities across Europe.
Conclusion
MI5’s latest assessment shows why Ireland breaking news coverage must increasingly include cyber security, foreign interference and artificial intelligence. The intelligence service says threats are growing in scale and sophistication, but early detection, international cooperation and responsible technology governance can help reduce the danger.
As AI develops, security agencies will need to separate genuine risks from speculation while acting quickly against extremist and state-backed operations. For the public, awareness and reliable information remain essential defences.
