5 Ways AI Is Changing the Cyber Threat Landscape

Artificial intelligence is changing the way organisations work, but it is also changing the way cyber criminals operate. The important point is that AI isn’t necessarily creating completely new types of cyber attack. Instead, it is helping attackers make existing techniques faster, more scalable and more effective.

The UK’s National Cyber Security Centre (NCSC) has assessed that AI will almost certainly increase the frequency and impact of cyber attacks, with threat actors already using AI to support activities including reconnaissance, social engineering, vulnerability research and malware development. So what does this actually mean for businesses?

Here are five ways AI is changing the cyber threat landscape:

1. Phishing is becoming faster and more convincing

Phishing has been around for years, but AI is making it easier to create convincing messages at scale. Attackers can use AI to generate emails, messages and other content that are tailored to a particular person or organisation. Poor spelling and obvious grammatical mistakes, once common warning signs, are becoming less reliable indicators of a suspicious message. The NCSC has specifically identified AI’s ability to improve social engineering and phishing as one of the areas where threat actors are already seeing a capability uplift. It also assesses that AI will make these techniques more effective, efficient and harder to detect.

This matters because phishing is often not the end goal. It can provide the initial access an attacker needs to gain a foothold in an organisation. For businesses, this makes security awareness increasingly important alongside technical controls. Security Awareness Training for employees is essential in helping employees recognise and respond to increasingly sophisticated threats.

2. Attackers can carry out reconnaissance more efficiently

Before launching an attack, criminals need to understand their target. That might involve researching an organisation, identifying employees, looking for exposed services or gathering information about the technology it uses. AI can help speed up parts of this process. The NCSC reports that threat actors are already using AI to enhance reconnaissance and information-gathering activities. Its latest assessment also highlights AI-assisted vulnerability research and exploit development as an area likely to become increasingly significant. The result is a changing balance between attackers and defenders.

Organisations have always needed to understand what is exposed to the internet and where vulnerabilities exist. As AI makes reconnaissance more efficient, maintaining good visibility of your environment becomes even more important. That includes knowing what systems you have, what is exposed, which vulnerabilities need addressing and where your critical data and services sit.

3. The barrier to entry is getting lower

You don’t necessarily need to be an expert cyber criminal to benefit from AI. One of the concerns highlighted by the NCSC is that commercially available and open-source AI models are making useful capabilities more accessible to less-skilled threat actors. This doesn’t mean every attacker suddenly has the capabilities of a highly sophisticated threat group. Instead, relatively basic tasks can become easier, allowing attackers with less technical expertise to improve the quality and efficiency of their operations. That has an important implication for businesses:

The threat isn’t limited to highly sophisticated attackers.

AI can give a wider range of threat actors access to capabilities that previously required more time, knowledge or resources.

4. AI can help attackers process huge amounts of information

Cyber attacks can generate large amounts of information. Once attackers have obtained data, they need to work out what is valuable, what is useful and where it might help them achieve their objective. AI is particularly well suited to processing and analysing information at speed. The NCSC has warned that AI will almost certainly allow threat actors to analyse exfiltrated data more quickly and effectively, potentially increasing the value and impact of cyber attacks. This is another example of AI acting as a force multiplier rather than necessarily introducing an entirely new attack technique. The technology can help attackers spend less time on repetitive analysis and more time identifying opportunities.

5. AI itself is becoming part of the attack surface

There’s another side to the AI security conversation that businesses shouldn’t overlook. As organisations introduce AI tools into their environments, those systems become part of the technology they need to secure. AI models can interact with business data, applications, users and other systems. This creates new considerations around access, data protection, configuration and how those systems interact with the wider IT environment.

The NCSC’s latest assessment warns that the growing incorporation of AI systems across the UK’s technology base is creating an additional attack surface for adversaries. It highlights techniques including prompt injection, software vulnerabilities and supply-chain attacks as potential ways AI systems could be exploited. NIST has similarly identified security concerns around AI agents, noting that existing cybersecurity principles remain important but may need to be adapted to address the specific risks created by increasingly capable AI systems.

For organisations adopting AI, the question therefore isn’t simply: “How can we use AI?” It is also: “How do we use it securely?”

AI is changing the threat landscape but the fundamentals still matter

It’s easy to view AI as something that has completely transformed cyber attacks overnight. The reality is more nuanced. The NCSC’s assessment is that, in the near term, AI is primarily enhancing existing tactics and techniques rather than creating entirely new threat vectors.

What is changing is the speed, scale and accessibility of these activities.

That means organisations need to keep looking beyond individual security products and consider the bigger picture: visibility, configuration, vulnerability management, identity, user behaviour and how quickly they can detect and respond when something doesn’t look right. Our Cyber Security Services are designed to help organisations take a more joined-up approach to protecting their environments as the threat landscape continues to evolve.

What does AI mean for the next cyber attack?

AI is already being used by both attackers and defenders, and its capabilities will continue to develop. The NCSC expects AI to increase the frequency and intensity of cyber threats through 2027, while also recognising that AI can be used to strengthen cyber security and resilience. For businesses, the challenge isn’t to predict exactly what the next AI-powered attack will look like. It’s to make sure the fundamentals are strong enough to withstand an increasingly capable and fast-moving threat landscape. And that means asking a difficult question:

If an attacker does get through, how prepared are you for what comes next?
