Meta's Muse AI agent was used to repeatedly re-add items to The RealReal's shopping cart, exploiting a 20-minute hold mechanism to indefinitely block other users from purchasing luxury goods. This represents a real-world abuse of agentic AI capabilities to cause denial-of-service conditions on e-commerce platforms. The RealReal has since updated its bot defences to restrict AI agent login, cart, and checkout actions.
Meta and partners including Walmart, Stripe, and Sierra are developing an open protocol to distinguish legitimate consumer AI agents from malicious bots when interacting with commercial websites. For defenders, this represents a meaningful step toward structured trust frameworks for agentic traffic — closing the gap between legacy anti-bot controls and the emerging reality of authorised AI-driven sessions. The protocol remains nascent, and significant adoption and integration maturity is required before organisations can rely on it as a meaningful trust signal.
Security researcher Patrick Wardle demonstrated a proof-of-concept attack against Meta's Muse AI assistant on macOS, showing that a hidden, undocumented preference key (`endo_voyager_dictation_endpoint`) can be silently modified by any process running as the logged-in user to redirect dictation audio and session tokens to an attacker-controlled server. The attack requires local code execution but can be bootstrapped remotely via a ClickFix social-engineering lure, requiring no download or installation. Once hijacked, an attacker can inject malicious instructions into Muse, capture its authentication token, and control the assistant across all of the victim's linked devices — including mobile and smart-home integrations.
