AI Helped Find a Critical PHP Bug. Attackers Didn't Wait.

from Daily AI Signal

Two separate teams, both working with AI models, found the same critical flaws in PHP, the language behind WordPress, Drupal and many other websites. PHP patched them on Wednesday, but Amazon saw an exploit attempt four days before disclosure. We go through who found what, how OpenAI coordinated the fix, and why the gap between finding and patching bugs is now the thing to watch. Also today: Microsoft says a China-state aligned group used the ARTEX AI agent framework through compromised ConnectWise apps to try more than 2,250 Microsoft 365 tenants. OpenAI's GPT-6 models arrive on Google Cloud in private preview. Anthropic opens a waitlist for Claude Duet, an agent that messages you first. And Meta spent about $35 billion on capex in one quarter. Quick hits: Nvidia's OpenShell reference design for safe agents, President Trump's data-center power post, and a DeepMind engineer's resignation over military work. Every story is checked against its sources; links below. This show is written with Claude, Anthropic's model.
