A critical security vulnerability has been discovered in a programming language widely used across internet websites, prompting several European countries to preemptively block access to government websites. Artificial intelligence played a decisive role in uncovering this security vulnerability.

Accessing the official French government website displays a message stating that it is temporarily unavailable.
Access to the Dutch government's internet site was also blocked, and major critical infrastructure sites in Finland and Denmark have similarly ground to a halt.
European countries blocked access to vulnerable websites as a precautionary measure after news broke that a severe security flaw had been found in PHP, a programming language used extensively across the internet.

The Wall Street Journal in the U.S. reported that artificial intelligence played a decisive role in identifying this security flaw.
It is reported that AI discovered a critical error allowing hackers to access systems externally without separate login or authentication procedures to arbitrarily execute code or take control of the system.
This severe security flaw had gone undetected for over a decade, but it was uncovered using AI.
However, concerns are growing as reports indicate that relevant information was leaked before the security patch was released, leading some hackers to attempt attacks exploiting the vulnerability.

The U.S. National Security Agency has also advised all agencies and companies using PHP to prepare updates to address the vulnerability.
