- Wiz: at least nine AI developer platforms breached in October, driving LLMjacking.
- EMBRACE: built-in browsers in five AI coding tools could run commands or read the disk.
- Epoch: open-weight GLM 5.3 exploited six Firefox releases for about $1,000 each.
- Prompt caching took one agent to up to 94% cache reads, about a quarter of the bill.
- Apple Intelligence's Qwen access opens for testing in China on November 4.
AI developer tooling took the hits today: Wiz counts at least nine AI developer platforms breached in October, and EMBRACE found command-execution flaws in the built-in browsers of five coding tools.
Meanwhile inference keeps getting cheaper, with Anthropic tokens down 77% and prompt caching reaching up to 94% cache reads in one measured agent.
