Cybersecurity and AI: What’s Changing, and What Comes Next?

AI is changing cybersecurity by accelerating familiar attack and defense tasks while expanding the risks around AI systems and generated code. The evidence points to a consequential shift, not routine autonomous attacks.

Yes—AI is already changing cybersecurity, but the best-supported picture is acceleration and amplification, not a wholesale reinvention. Attackers and defenders can use AI to do parts of familiar work faster, while AI systems and AI-generated code create risks that organizations must secure. That is a meaningful shift, but it is not evidence that cyberattacks are routinely autonomous or that human defenders are obsolete.

How is AI changing cybersecurity right now?

The clearest near-term change is that AI can help people carry out existing cyber tasks more efficiently. The UK National Cyber Security Centre (NCSC) says threat actors already use AI to support reconnaissance, vulnerability research and exploit development, social engineering, basic malware generation, and analysis of stolen information. Its assessment expects these capabilities mainly to improve existing tactics through 2027, rather than to produce a wave of entirely new attack methods. NCSC, Impact of AI on cyber threat from now to 2027 (2025).

That forecast is not a claim that every attacker has advanced AI capability. The NCSC assesses that well-resourced, highly capable actors are better positioned to exploit advanced tools; other groups may use or adapt commercial and open-source models. The likely result is uneven adoption, with AI helping some actors increase the speed, scale, or effectiveness of particular operations.

Google Threat Intelligence Group (GTIG) reported in May 2026 its first identified case of a threat actor using a zero-day exploit it believes was developed with AI, alongside AI-assisted development of adversary infrastructure and malware. GTIG also described malware that can interpret system state and generate commands, and attacks targeting AI environments and software dependencies. These are attributed observations from one threat-intelligence group—not a measure of how common such activity is across all attackers. Google Threat Intelligence Group, May 12, 2026.

Why are vulnerabilities and patching a pressure point?

AI-assisted vulnerability research and exploit development are a particular concern because they can put pressure on the time defenders have to respond. The NCSC says the period between vulnerability disclosure and exploitation has already shrunk to days, and expects AI to reduce it further. Known vulnerabilities in systems that remain unpatched are a likely target.

This makes timely vulnerability management more important, not less. Organizations need to identify exposed systems, prioritize fixes, and verify that patches have been applied. The NCSC also warns of increased risk to critical national infrastructure and its supply chains, including operational technology that may have lower security levels. Its statements are a forecast through 2027, not a claim that every disclosed flaw will be exploited.

Does AI make cyberattacks autonomous?

Not according to the NCSC’s near-term assessment. It considers fully automated, end-to-end advanced cyberattacks unlikely by 2027. Skilled people are expected to remain involved, while automating selected stages such as vulnerability identification, exploitation, or changing malware and infrastructure to evade detection. In other words, automating parts of an attack chain should not be confused with a fully independent operation.

The distinction matters: AI can increase the pace of work without removing the human decisions, access, and operational control involved in an advanced intrusion. The NCSC also cautions that the technology is changing quickly and that technical surprise is likely, so this forecast should be read as time-bounded rather than permanent.

AI creates risks when organizations deploy it, too

AI is not only a tool an attacker might use; an AI system connected to company data, software, or operational technology can itself become part of an organization’s attack surface. The NCSC identifies direct and indirect prompt injection, software vulnerabilities, and supply-chain attacks as possible routes into AI systems and, potentially, into wider connected systems. Rushed deployment can put release schedules ahead of security; weak encryption, poor identity management, and excessive data collection can add exposure. NCSC assessment.

AI-generated code needs the same security discipline as other code: teams should understand what they are deploying, review it, and maintain the dependencies and systems it relies on. NIST’s SP 800-218A supplements its Secure Software Development Framework with practices and tasks for generative AI and dual-use foundation models. It is intended for model producers, producers of systems that use models, and acquirers of those systems, and is meant to be used alongside NIST SP 800-218A.

In a July 2026 report on generative AI in software engineering, eu-LISA says AI coding assistants may support productivity gains but emphasizes evaluating tools over time, monitoring changes, and resourcing the review of generated code. The practical point is not that every AI-generated line is unsafe; it is that generated code still needs accountable engineering review. eu-LISA, July 9, 2026.

Can defenders use AI to improve security?

Yes. The same broad advances can support defensive work. GTIG reports using AI agents to identify software vulnerabilities and reasoning systems to help fix them. That is an example of a capability reported by the vendor, not proof that an AI tool will reliably secure any organization or eliminate the need for security engineers. The National Academies’ 2026 rapid expert consultation likewise frames generative and agentic AI as expanding capabilities for both attackers and defenders, with near-term risks as well as longer-term opportunities. National Academies, Implications of AI for Cybersecurity (2026).

What do cybersecurity practitioners report about AI adoption?

SANS Institute’s July 2026 survey drew on 536 security practitioners and 57 senior leaders globally. Its figures describe respondents’ reports and views; they are not independently measured global rates of AI use or attack incidence.

2026 SANS survey finding What it measures
78% of surveyed organizations Reported active AI use in cybersecurity.
27% of practitioners Described their AI deployments as mature production.
63% of practitioners Reported significant shortcomings in AI threat detection and response, up from 45% in the 2025 survey.
78% of organizations Reported confirmed or suspected AI-enabled attacks in the past year; this is a survey response, not a measured global incidence rate.
95% of respondents Believed threat actors were already using AI.
73% of practitioners Said AI had changed their team’s training requirements, up from 51% in 2025.
61% of practitioners Reported using AI in red-team work, up from 33% in 2025.
50% of senior leaders; 36% of practitioners Reported that their organization had a formal AI risk program, showing a difference between the two respondent groups.

The pattern in the survey is a gap between adoption and readiness: reported use is broad, but relatively few practitioners describe deployments as mature, and many report detection and response shortcomings. The SANS results do not establish why organizations have these gaps or how each organization should address them. SANS Institute, AI in Cybersecurity (July 2026).

What should organizations do differently?

The sources point to established security work that becomes more urgent as AI changes the pace and expands the systems organizations need to protect:

  • Keep vulnerability response moving. Track exposed assets, prioritize known vulnerabilities, and verify fixes rather than assuming disclosure gives teams ample time.
  • Secure AI integrations. Review what an AI tool can access, how it connects to other systems, and how identities, data, and permissions are managed. Consider prompt injection, software flaws, and dependency or supply-chain risk as part of the threat model.
  • Apply secure development practices. Use lifecycle controls suited to AI systems and models, drawing on NIST SP 800-218A alongside the SSDF.
  • Review generated code and dependencies. Evaluate tools, monitor changes, and assign enough engineering capacity to understand and inspect what is deployed.
  • Prepare the people doing the work. SANS respondents report that AI is changing team training needs; organizations should ensure security staff can assess AI-related risks as well as use relevant defensive tools.

These are risk-response priorities, not guarantees that any single control will prevent an AI-related incident.

Is cybersecurity changing as dramatically as software development?

The comparison is useful as a question, not as a proven equivalence. AI is changing how security teams and attackers can perform parts of their work, and organizations are also taking on new risks when they connect AI to code, data, and infrastructure. But the evidence available here supports a more specific conclusion than “cybersecurity is unrecognizable”: through 2027, the NCSC expects AI chiefly to amplify existing intrusion methods, while human expertise remains central to advanced operations.

The change is consequential because speed matters in vulnerability response and because AI adoption adds systems that need oversight. It is also dual-use: the same broad advances can assist discovery and repair as well as exploitation. How disruptive the shift becomes will depend in part on whether organizations can match adoption with secure engineering, review, and workforce readiness.
