Google announces Gemini has reached 1 billion monthly active users (MAUs) in the Gemini app, with voice input driving most usage. The milestone mirrors OpenAI’s ChatGPT and signals Gemini’s rapid integration across Google products, while OpenAI and others continue to compete in the AI race.
Security researchers have found two critical vulnerabilities in the PHP programming language, labelled PHP2Shell, and PHP maintainers have released emergency patches. Governments and major tech firms have urged operators to update immediately or temporarily take sites offline after AI-assisted research and an early public leak triggered millions of exploitation attempts between 21–27 October 2026.
Vulnerabilities in PHP, a core technology powering about 70% of websites, have prompted governments and major sites to take systems offline to patch critical flaws. OpenAI researchers credit frontier AI with help in discovering the bugs, and cybersecurity teams warn that exploitation could allow data theft and server takeover. Patches have been issued, and authorities urge immediate updating.
Advanced AI models and open-source hacking tools have exposed and helped exploit long-hidden software vulnerabilities. Firms have linked autonomous tools like Artex to active attacks, while frontier models have found thousands of bugs in PHP and other critical codebases. Organisations are patching systems and warning that AI will accelerate both discovery and malicious reuse of flaws.
