Terrorists could use AI to target UK with drones and bioweapons, MI5 chief warns

The MI5 chief warned that terrorists could use artificial intelligence to target the UK with drones and bioweapons. The warning matters because AI may help attackers plan, adapt, and scale operations faster than before. It could also lower the technical knowledge needed for some dangerous activities.

A drone attack might involve commercially available aircraft guided toward a target, while AI could assist with navigation, image analysis, or selecting targets. Biological threats are more complex, but AI could help process scientific information or support planning. The article’s related warning describes AI as “supercharging” security threats involving drones, cyberattacks, and biological weapons.

This does not mean every terrorist group can immediately carry out such attacks. It means intelligence agencies must assess rapidly changing tools alongside traditional extremist and state threats. MI5 also warns that rightwing extremists are increasingly likely to consider terrorist attacks, making technology-enabled threats part of a wider and evolving security challenge.

MI5, formally the Security Service, is the United Kingdom’s domestic intelligence agency. Its role is to protect national security within the UK, especially against terrorism, espionage, and hostile-state activity. Unlike a police force, it primarily gathers and assesses intelligence, then works with law-enforcement and other agencies to reduce threats.

In practice, MI5 may investigate suspected terrorist networks, identify people involved in attacks, and share information that supports arrests or disruption. It can also track espionage and state threats. The source highlights that MI5 is dealing with more state threats than during the Cold War, showing that its work extends beyond terrorism.

MI5 does not operate in isolation. Counterterrorism depends on intelligence sharing, policing, surveillance under legal safeguards, and cooperation with partners. The warnings about AI, rightwing extremism, drones, and bioweapons show why its mission must adapt as both ideologies and technologies change.

When officials say AI could “supercharge” threats, they mean it may increase the speed, scale, precision, or accessibility of harmful activity. AI can automate tasks that once required specialist time, such as analysing information, generating convincing messages, or helping plan operations. That could benefit attackers using drones, cyber tools, or biological knowledge.

For example, an attacker might use software to analyse drone-camera images, choose routes, or coordinate several devices. In cyberattacks, automated systems can search for weaknesses or produce tailored messages. In biological work, AI might help organise published scientific information. These tools do not remove the need for materials, access, expertise, or physical action.

The article presents this as a growing security concern, not proof that every threat is imminent. MI5 must therefore watch how widely capable tools spread and how extremists or hostile states combine them. The central risk is acceleration: existing threats may become easier to attempt and harder to detect in time.

Commercial drones are widely sold, and many AI services are accessible through ordinary digital platforms. Basic biological knowledge is also available in textbooks, research papers, and online resources. Together, these trends can lower some barriers to terrorism. However, access to information is not the same as possessing the facilities, materials, skills, or opportunity needed for a successful attack.

A potential attacker could buy a drone, use software to analyse images, and find public information about targets or methods. AI might help organise that information or automate parts of planning. Biological attacks generally require far greater control, equipment, safety procedures, and specialist ability. The danger lies in reducing some early-stage obstacles, not making every operation simple.

The source gives no figures for availability, cost, or capability. It does show that MI5 sees AI as intensifying threats and that terrorists could consider drones and bioweapons. Security agencies therefore face a broad pool of accessible tools, alongside the continuing challenge of distinguishing harmless use from preparation for violence.

The source gives a striking comparison: MI5 is tackling more state threats now than during the Cold War. That suggests the modern security environment is not simply less dangerous because the Cold War ended. Instead, threats have multiplied across different actors, technologies, and methods.

During the Cold War, state espionage and confrontation between major powers dominated much of the intelligence landscape. Today, MI5’s warnings also cover terrorists using AI, drones, and biological weapons, along with cyberattacks. The agency has separately warned that rightwing extremists are increasingly likely to consider terrorist attacks. These examples show a wider mix of state and non-state dangers.

The source does not provide a numerical comparison or explain precisely how threats are counted. It does establish that MI5’s workload from state threats exceeds its Cold War level. The implication is that intelligence agencies must manage overlapping risks, rather than focus on one clear geopolitical rivalry or one traditional form of espionage.

A drone attack could injure people, damage buildings, disrupt transport, or strike a sensitive site. Its effects would depend on the drone, payload, target, and timing. A biological weapon could cause illness, deaths, fear, and pressure on health services. The consequences might extend well beyond the place where the agent was first released.

Biological attacks are particularly difficult to contain because contamination and infection may be invisible. People may not realise they have been exposed, and symptoms can take time to appear. During that interval, individuals could move through communities. Responders would need to identify the agent, trace contacts, protect medical staff, and limit further spread.

The source does not describe a specific planned attack, casualty estimate, or biological agent. It reports the MI5 chief’s warning that terrorists could use AI with drones and bioweapons. The forward concern is that faster planning and wider access to tools could make rare but potentially severe threats harder to anticipate.

Intelligence agencies try to stop attacks before they happen by gathering information about suspected networks, assessing risks, and identifying preparations. They may combine human intelligence, digital evidence, surveillance, and reports from partner agencies. When evidence reaches the required threshold, police or security services can investigate, arrest, disrupt plans, or impose other lawful measures.

A simple example is connecting several clues: extremist statements, suspicious communications, unusual purchases, or efforts to obtain attack equipment. One clue may mean little, but a pattern can reveal intent. Agencies then share relevant intelligence with police and other authorities. Exact methods are often secret, so the source does not describe MI5’s operational techniques.

No system catches every threat. Agencies may lack information, misunderstand a person’s intentions, or face too many signals to examine immediately. Attackers can act alone, change methods, or use accessible technology such as AI and drones. The warnings about rising rightwing extremism and expanding state threats show why prevention requires constant adaptation rather than a final solution.
