The Five Eyes cyber security agencies have issued a joint warning that artificial intelligence is rapidly accelerating cyber threats, including the exploitation of zero day vulnerabilities, and urged organizations to act immediately.

In a statement released on June 22, 2026, senior leaders from agencies across the United States, United Kingdom, Canada, Australia, and New Zealand emphasized that the evolution of AI is reshaping both offensive and defensive cyber capabilities at a pace measured in months rather than years.

Five Eyes Agencies Warn AI
According to the CISA, AI is significantly lowering the barrier to entry for threat actors while increasing the speed, scale, and sophistication of attacks. Advanced AI models are expected to outperform current expectations, enabling attackers to automate reconnaissance, vulnerability discovery, and exploit development.

This shift is already reducing the time between vulnerability disclosure and active exploitation, creating a critical challenge for defenders who rely on traditional patching and mitigation timelines.

The agencies warned that zero-day vulnerabilities will become more prevalent as AI systems introduce new classes of software flaws and logic errors that are difficult to detect with conventional methods.

At the same time, adversaries are increasingly leveraging AI to identify these weaknesses before vendors can respond, amplifying the risk to critical infrastructure, enterprise environments, and supply chains.

The Five Eyes alliance stressed that cyber risk is no longer a purely technical issue but a core business concern that requires executive-level accountability.

Organizations are being urged to reassess their cyber resilience strategies, ensuring that security controls are not only implemented but also capable of withstanding real-world attack scenarios. The statement highlights that failure to adapt will result in operational disruption, financial loss, and long-term strategic disadvantage.

To mitigate these risks, the agencies outlined several urgent actions. Organizations are advised to reduce their attack surface by limiting unnecessary system exposure and isolating critical assets.

Accelerating patch management is identified as a priority, particularly as AI-driven threats shrink remediation windows. Legacy and unsupported systems are considered high-risk liabilities that must be addressed or replaced.

Identity and access management remains a key focus, with recommendations to enforce strong authentication mechanisms and regularly audit user privileges. Additionally, organizations are encouraged to prepare for inevitable breaches by testing incident response plans and ensuring rapid containment capabilities.

While highlighting the risks, the agencies also noted that AI can strengthen cyber defense when applied effectively.

Security teams can leverage AI-driven tools to improve threat detection, identify vulnerabilities earlier in the development lifecycle, and accelerate incident response. However, the statement cautions that success depends on integrating AI into a broader security strategy rather than relying solely on new technologies.

The Five Eyes warning underscores a growing consensus within the cybersecurity community that AI is fundamentally altering the threat landscape. Organizations that prioritize foundational security practices while adopting AI-driven defense mechanisms are more likely to maintain resilience as the pace of cyber threats continues to accelerate.

If this quote is accurate, the overall message aligns with what many national cyber agencies have been emphasizing for a while: AI is mainly an accelerant (faster recon, better social engineering, quicker weaponization), which compresses defender timelines.

That said, I can’t verify the specific “June 22, 2026” joint statement from this excerpt alone. For something this consequential, it’s worth confirming via the agencies’ official sites/press releases before treating any details (especially around “more prevalent zero-days”) as authoritative.

What’s solid in the advice (regardless of the exact press release)
These are the controls that still move the needle the most when attacker speed increases:

• Patch and mitigate faster (time-based security)
  Prioritize internet-facing systems and “known exploited” vulnerabilities first. If your org can’t consistently patch critical external services quickly, add compensating controls (WAF rules, virtual patching, strict allowlists, segmentation) until you can.
• Reduce attack surface
  Remove/disable unused services, close inbound exposure, restrict admin interfaces to VPN/ZTNA, and aggressively inventory shadow IT. AI helps attackers find “forgotten” assets faster.
• Identity hardening
  Enforce phishing-resistant MFA where possible (FIDO2/WebAuthn), minimize standing privileges, monitor for impossible travel/token misuse, and protect privileged accounts with separate admin identities and tighter conditional access.
• Assume compromise: containment readiness
  Test incident response with realistic scenarios (ransomware + data theft). Make sure you can isolate endpoints quickly, revoke tokens/sessions, rotate secrets, and restore from offline/immutable backups.
• Visibility and detection engineering
  Centralize logs (identity, endpoint, cloud control plane, DNS, email). Detection quality matters more than “having a tool,” especially if adversaries can iterate faster.
• Supply chain and third-party risk
  Maintain SBOMs where feasible, control update channels, and monitor for unusual vendor access paths. Faster exploit cycles make supplier incidents spread more quickly.

A note on “AI will increase zero-days”
It’s plausible that AI-assisted research could reduce the cost of finding certain bug classes, but “more zero-days” is hard to assert confidently without public data over time. What is already observable is the shrinking gap between disclosure and exploitation for high-value products, and AI can further compress that window.

Practical takeaway
Whether or not the quoted statement is word-for-word correct, the defensive response is the same: shorten patch/mitigation timelines, harden identity, reduce exposure, and verify incident-response readiness. AI tooling can help, but it won’t compensate for weak fundamentals.

Perhaps this could also be an opportunity for vendors to use AI in their testing and reviews, strengthening security before releasing products. Sometimes less rush and more care can make all the difference.
