Canadian cybersecurity agency warns AI is reshaping cyber threats

Canada’s Centre for Cyber Security has warned that frontier AI models are rapidly transforming the cyber threat landscape, reducing the time organisations have to detect, contain and respond to attacks.

According to the Cyber Centre, AI is enabling cybercriminals to identify vulnerabilities, automate complex attack chains and generate increasingly convincing phishing campaigns, deepfakes and voice impersonation attacks at unprecedented speed and scale.

The advisory follows a joint statement by the Five Eyes cybersecurity agencies urging organisations worldwide to strengthen cyber resilience before AI-enabled attacks evolve into major operational, financial and national security incidents.

The Cyber Centre also highlights internal risks associated with unapproved AI use, including the exposure of sensitive information and reliance on inaccurate or manipulated AI-generated outputs.

Rather than viewing AI solely as a source of risk, the Cyber Centre encourages organisations to integrate frontier AI into cybersecurity operations. AI can help identify vulnerabilities earlier in software development, strengthen secure-by-design practices, improve security monitoring and accelerate incident detection and response.

The guidance emphasises that fundamental cyber hygiene, including timely patching, phishing-resistant multi-factor authentication, network segmentation, centralised logging and regularly tested incident response plans, remains essential despite rapid advances in AI capabilities.

Why does it matter?

The guidance reflects a shift in cybersecurity from preparing for future AI risks to responding to immediate operational challenges. As frontier AI enables attackers to identify vulnerabilities, automate exploitation and produce more sophisticated phishing and social engineering campaigns, organisations may have less time to detect and contain incidents.

The advisory also reinforces an emerging consensus among the Five Eyes partners that AI should be treated as both a cyber risk and a defensive capability. Alongside robust governance and responsible AI use, organisations are increasingly expected to combine AI-enabled security tools with strong cyber hygiene, secure-by-design practices and resilient incident response capabilities to keep pace with a rapidly evolving threat landscape.
