Inside the Race to Contain 'Internet Chaos'

Security1 min read

A race is on to patch two serious flaws, called PHP2Shell, in PHP, a common programming language used to run websites. Security teams found them months ago but must fix them before hackers use AI to attack at scale.

What happened

Security researchers found two serious bugs in PHP, a language that powers many web servers. The bugs, named PHP2Shell, let attackers run unauthorized software on any web server that has not been fixed. Calif Research, a US security startup with many Vietnamese team members, was the first to find one of them. Experts worked together in an unofficial group to build patches before the flaws became widely known.

Key numbers and facts

  • Two flaws were found, both named PHP2Shell.
  • Some attacks could take only a few seconds on small systems, and hours on complex ones.
  • Fixing the problem meant changing nearly 200 files.
  • Developers wrote more than 10,000 lines of code during the work.
  • The planned patch release date was October 22, but the flaw became public on October 21.

Why AI matters here

Researchers used AI models from OpenAI and Google to find the flaws. According to Calif Research, this kind of flaw had hidden in PHP code for years because it was very hard to exploit. AI helped find a way. Experts compare the risk to Heartbleed, a 2014 flaw that forced the world to protect hundreds of thousands of servers.

Why it matters

Many websites run PHP, so an unpatched server can be taken over by attackers. If hackers learn how to use the flaw before fixes are installed, the damage could spread fast. The story shows how AI can help both defenders and attackers find weak points in software.

What to watch

  • Whether website owners install the patches quickly.
  • Whether hackers use AI to build attacks from the public details.
  • How security teams and AI companies share bugs before they are made public.

Tioli Releases Emergency Response Guide for 'Node2Shell'

Tioli said on the 26th that it had independently reproduced and verified the Node.js vulnerability 'Node2Shell (CVE-2026-111497)', disclosed on the 21st, and published a response guide. The flaw stems from a memory-handling error when decompressing Brotli-compressed data, and Node.js rates its severity as High. Patched versions 22.23.4, 24.22.1, and 26.12.1 were released.

The Privacy Risks of "Always-Listening" AI Devices

AI-enabled devices such as smart speakers, smartwatches and smart glasses that are always ready to respond can collect data, raising privacy concerns. Global shipments of AI glasses reportedly jumped to 8.4 million in 2025 from 2.1 million in 2024, according to Omdia data cited by Reuters. Experts warn that bystanders may be monitored without owning any device, and that AI can interpret far more collected information than earlier voice assistants.
