Secure Courier is a consent flow in Tollbooth DPYC, a monetization network for paid MCP services, that lets an AI agent act for a Nostr npub without holding the user's nsec. The service sends a signed, sealed direct message over Nostr relays, the user replies with a signed approval and an expiry, and the service issues its own encrypted grant. Lonnie VanZandt presents it as an alternative to central identity providers and CIBA. The thread gives no audit results.

Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe. A postMessage handler from the MathLive virtual keyboard used innerHTML, letting sandboxed code inject an unsandboxed iframe. A YouTube oEmbed endpoint allowed by the CSP reflected JavaScript, enabling exfiltration of private data via a ChatGPT share URL. OpenAI fixed it and paid a $5,000 bounty.

Hotseat is a free, open-source macOS menu bar app that moves Claude Code and Claude Desktop to another of the user's Claude accounts in one click and returns to the same session. Sessions, settings, skills and MCP servers are shared, so `claude --resume` works under either account. When a session hits a usage limit, it offers to continue under another account. It never reads tokens or cookies. Install with Homebrew.

On-policy state training is a method for training chain embedding retrievers for multi-hop RAG on the states the encoder itself reaches, including those built on its own wrong retrievals. Each state is labeled with the earliest missing gold passage, other missing gold passages are masked, and updates are contrastive and mixed with teacher-forced states. It retrieves complete evidence more often than teacher-forced training and graph-based systems, and transfers to harder long-chain HotpotQA and 2WikiMultiHopQA variants the authors built.

Clean-label poisoning attack on federated learning for Basic Safety Message anomaly detection in vehicular networks, from Sagduyu, Erpek, Stephenson and Xue (paper submitted 23 October 2026).

A feature-consistency relabeling defense keeps attack success low without hurting clean accuracy, and a game-theoretic model shifts equilibria against attacking.
