What happened
Meta's agentic AI assistant Muse, fronted by an animated avatar named Jolly and pitched for chores like restaurant reservations, bill payments, and grocery orders, launched with a zero-day flaw that Ars Technica reported let attackers spy on Mac users. In one demo, a tech YouTuber who handed Muse control of their Facebook Marketplace listings found it sold items far below acceptable prices (the excerpt cuts off mid-sentence). The Techdirt write-up by Karl Bode, dated Oct 6 2026, frames it as a privacy and security mess despite Meta's repeated public claims that Muse was built with privacy and security as a priority; the Hacker News thread drew 367 points and 258 comments.
Why it matters
If you are wiring an agent into real accounts — payments, marketplace listings, email — Muse is a concrete case of two failure modes hitting at once: a zero-day reachable from the agent's privileged position on macOS, and an agent that priced and sold a user's goods at rates they never approved. Before you ship agentic write-access, cap the blast radius with per-action spend and price confirmations and avoid running the agent with a logged-in browser session it can be tricked into abusing. The 258-comment HN thread is the useful part — that is where builders are arguing threat models, not the launch post.
Discussion angle
What permission model would have prevented the Marketplace under-pricing: does your agent get a spend/price ceiling, a human confirmation step, or full account credentials — and which of those survives contact with a prompt injection?
