The defining cybersecurity story of 2026 is not a new category of attack. It is the acceleration of old ones. Adversaries are not reinventing their playbooks. They are speeding them up with AI, compressing the time between scanning a target and causing impact. The major threat reports of the year, from IBM, CrowdStrike, the World Economic Forum and Verizon, all point to the same shift.
AI as a force multiplier for attackers
Across the leading intelligence reports, AI shows up as a dual threat. It multiplies the speed and scale of attacks while also creating an entirely new attack surface.
CrowdStrike recorded an 89 per cent increase in attacks from AI-enabled adversaries, with the fastest recorded breakout time dropping to 27 seconds and the average to 29 minutes. IBM's X-Force team observed a 44 per cent year-over-year rise in attacks that began with the exploitation of public-facing applications, driven partly by AI-enabled vulnerability discovery. The World Economic Forum's Global Cybersecurity Outlook found that 87 per cent of respondents identified AI-related vulnerabilities as the fastest-growing cyber risk of the year.
The headline numbers
The scale of the shift is best seen in the aggregate data from 2025 into 2026.
| Metric | Figure | Source |
|---|---|---|
| Increase in AI-enabled adversary attacks | 89% | CrowdStrike 2026 |
| Increase in active ransomware groups year over year | 49% | IBM X-Force 2026 |
| Rise in exploitation of public-facing applications | 44% | IBM X-Force 2026 |
| Share of breaches caused by vulnerability exploitation | 40% (X-Force) / 31% entry points (Verizon) | IBM, Verizon 2026 |
| Increase in major supply chain compromises since 2020 | Nearly 4x | IBM X-Force 2026 |
| Respondents naming AI vulnerabilities the fastest-growing risk | 87% | WEF 2026 |
| Global cybersecurity market (2026) | 211.69 billion US dollars | Statista Market Insights |
Vulnerability exploitation overtakes stolen credentials
A notable change in 2026 is that vulnerability exploitation has become the leading way attackers get in. The Verizon Data Breach Investigations Report, which analysed more than 22,000 confirmed breaches, found vulnerability exploitation accounted for 31 per cent of breach entry points, overtaking stolen credentials. Many of these vulnerabilities require no credentials at all, which lets attackers bypass humans and move straight from scanning to impact.
Ransomware is fragmenting, not fading
Ransomware remains a defining threat, but its economics are shifting. The ecosystem fragmented as active groups surged, while publicly disclosed victim counts rose more modestly. At the same time, more victims are refusing to pay, and median payments have declined, pushing groups toward pure-extortion attacks that steal data without encryption. This reduces operational complexity for attackers while maintaining pressure through the threat of exposure.
The forward-looking concern is autonomy. Several analysts expect agentic AI to handle critical portions of the ransomware chain, including reconnaissance, vulnerability scanning and even ransom negotiation, with reduced human oversight.
The supply chain weak link
Large supply chain and third-party compromises have nearly quadrupled since 2020, as attackers exploit trust relationships and the automation built into development and deployment pipelines. With AI-powered coding tools accelerating software creation and occasionally introducing unvetted code, the pressure on these pipelines is expected to grow.
What defenders should do
The reports converge on a consistent set of priorities:
- Close basic security gaps first, since missing authentication controls and unpatched public-facing applications remain the most exploited weaknesses.
- Adopt AI-driven and agentic detection and response, to match the speed of automated attacks. Internal detection rates reached 50 per cent in 2025, and faster detection carries a measurable cost advantage.
- Harden the software supply chain, with provenance, integrity checks and scrutiny of SaaS integrations and continuous-integration pipelines.
- Treat cyber as a continuous, measurable programme tied to business resilience, mapped to established frameworks rather than annual check-the-box exercises.
The core lesson of the 2026 reports is uncomfortable but clear. The fundamentals have not changed, but the speed has. Defenders who rely on manual response against AI-accelerated attackers are increasingly outpaced, and the path forward runs through both stronger hygiene and faster, automated defence.
