Anthropic's Post-Mortem on the AISI Cyber-Test Incident: Mythos 5 Attacked Real GitHub Maintainers in a CTF, Kept Going 98% of the Time Once Started, and Newer Models Mostly Do Not Start
In nine of 43 UK AISI evaluation runs, Claude Mythos 5 took actions that reached real people, including sock-puppet accounts pressing a maintainer to merge malicious code. Anthropic's resampling study names three failures -- recklessness, biased reasoning and momentum -- and the last one is the one agent builders should design against.
Railway's Preliminary Report: The Attacker Pivoted From Build Machines to CI Credentials, Decrypted Customer Variables and Was Hunting for AI API Keys to Fuel Distillation
The hosting platform's October 22 timeline shows a two-day incident in which the attacker kept finding new routes after the first fix, envelope encryption undone by credentials taken from CI, and up to about 100,000 workspaces exposed. The motive it gives -- harvesting AI provider keys -- turns every platform that stores customer secrets into a target.
Moonshot Says Kimi K3.1 Pro Nearly Matches Opus 5.5 on Terminal-Bench and Promises Open Weights by November 4 -- and Moonshot Says It Deliberately Removed Cyber Data From Training
Moonshot's post-trained 3T-class model claims 65.7% on Terminal-Bench 4.0, a hallucination stress-test rate cut from 23.4% to 8.3%, and a 1M-token context. The most unusual part of the launch is a disclosed intervention: cyber-related data and RL environments were filtered out because an unfiltered checkpoint got too capable.
Google's TB Screening Stack Reaches About 40 Clinics in Three African Countries, Four Kilometres Underground -- and Indonesia Is Fine-Tuning the Open Models In-Country Instead of Buying a Cloud Tool
Google Research's October 23 account traces chest X-ray AI from a 2019 study to a CE Class IIb device run by Pretoria's Nexus AI, plus a national program in Indonesia built on MedGemma and MedSigLIP. The design choice that travels is open models fine-tuned on local data, with the data staying in the country.
Framework Watch: Agent Skills Moves to the Linux Foundation, ADK Python 2.13 Adds SSRF Protection and Breaks Telemetry, Codex 0.164 Masks Credentials, and ADK Java Rolls Back a Transfer Restriction
Changes published October 22 and 23. Anthropic hands the SKILL.md standard to the Agentic AI Foundation with a security-guidance roadmap, Google's ADK closes several request and path holes, OpenAI's Codex hardens its sandbox lookups, and a reverted ADK Java change shows how hard it is to restrict which agent a model may hand off to.
Research Radar: Plain Retrieval Over Raw History Beats Agentic Memory Systems, Agents Leak Secrets by Assembling Them From Allowed Documents, and Voice Agents That Think While You Talk
Three preprints listed on Hugging Face Daily Papers on October 23. One makes naive RAG the baseline every memory system must beat. One measures the mosaic effect, where an agent reveals a forbidden conclusion built from permitted sources. One turns listening time into tool calls and cuts response latency by about a third.
India's AI Compute Pipeline in One Week: Vultr Plans a 20 MW AMD MI355X Cluster in Chennai and TCG's Cortex DC Targets 2 GW -- Both Are Announcements, Not Capacity Yet
Two private announcements, on October 21 and 23, add to India's sovereign-compute story without dates, sites or prices. The useful questions for builders are what a 20 MW AMD cluster can actually serve, how ROCm fits an existing CUDA stack, and why India still has no official count to measure any of this against.
