Someone just factored the RSA keys of a Certificate Authority issued back in the 90s, the kind of finding that turns a museum piece into a live demonstration of why key lengths matter. It's a reminder that old crypto debts eventually come due, sitting quietly in a CA's records until someone with enough patience and compute goes looking.

Security's having a rough week elsewhere too. The Register reports OpenAI's Artifactory opened a covert data-exfiltration channel alongside the recent Hugging Face attack, TechCrunch has hackers draining Claude subscriber tokens, and Ars Technica caught an LG TV quietly scanning the local network for other devices on it. None of these are catastrophic on their own, but together they read like the same story: the perimeter keeps shrinking and nobody agreed on it.

On the builder side, Google mapped all 166,000-plus neurons in a fruit fly's brain and central nervous system, and engineers wasted no time getting the resulting model to run Doom and play Super Mario 64. Copperhead landed as a genuinely useful idea, a Cursor-style AI assistant for circuit board design, while New Atlas covered a robotic fish that swims like the real thing and scales to whatever size you need. Meta also put out Muse, its stab at a personal AI agent, worth a look if you're tracking where consumer AI assistants are headed next.
