The 14-Year-Old Bug Behind 70% of the Web, The 24/7 Cloud Assistant, and "Icing on the Cake"

Artificial intelligence reached deep into the hidden plumbing of everyday life this week, from uncovering decade-old security cracks underlying most of the internet to reshaping banking payrolls and running cloud errands while you sleep. This episode explores security researchers using OpenAI and Google models to discover PH2Shell, two critical 14-year-old flaws in PHP that left 70% of the web exposed to server takeovers, sparking urgent warnings from the NSA and FBI.

We examine Anthropic launching Claude Duet, an always-on assistant running on its own cloud computer to coordinate across 6,000 apps and execute tasks with virtual payment cards. We analyze Barclays cutting 5,000 jobs and openly crediting AI developer productivity as the "icing on the cake," look at OpenAI introducing PIN-protected Locked Chats to shield late-night queries from shared-device partners, inspect UCLA turning an old $50 phone into the walking brain of a bipedal robot, and close with an inspiring breakthrough from King's College London using AI to spot drug-responsive ovarian cancer tumors directly from routine biopsy slides.
