“This is not a drill.”
— Lukasz Olejnik, visiting senior research fellow at King’s College London, on the PHP vulnerabilities, October 21, 2026
Today I attended the IT-ISAC’s threat presentation on cyberattack trends in 2026, titled “Make It Harder: Turning Today’s Cyber Threats into Action.” Among the trends it highlighted was one that should keep every executive and board member up at night: AI is accelerating vulnerability discovery, and with it, cyber risk itself.
The warning did not stay theoretical for long. Roughly coinciding with the presentation, government websites across Europe went dark. Their operators pulled them offline as a precaution against critical, AI-discovered vulnerabilities in PHP, the code running beneath most of the web. Hackers were already exploiting the flaws.
