Meta Muse AI Agent Hijacked via Hidden Dictation Endpoint
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.
