The cybersecurity landscape for Canadian public safety has undergone a sea change, as frontier AI models like Anthropic's Mythos enable threat actors to automate the discovery of zero-day vulnerabilities and perform high-speed reconnaissance at scale. With the attack lifecycle now compressed to just minutes, adversaries are moving from initial access to full data exfiltration faster than many traditional defenses can respond. This session begins with an expert brief on how AI-led phishing, automated enumeration, and voice cloning have industrialized the exploitation of mission-critical and enterprise networks. The second half features direct insights, and mitigation advice, from an ethical penetration tester who "hacks" public safety systems using these exact adversarial techniques to uncover unknown security gaps before they result in catastrophic service disruptions.
