Meta founder and CEO Mark Zuckerberg has gone to great lengths<\/a> to hype the security of its new AI assistant Muse, claiming it is \u201cbuilt from the ground up for privacy and security.\u201d A zero-day vulnerability that gives locally run apps and terminal commands complete control of the agent raises serious doubts. Further raising questions, Amazon on Sunday began blocking Muse from its site.<\/p>\n

Meta introduced<\/a> Muse a few weeks ago. The assistant \u201cbooks appointments, fills out forms and handles customer service,\u201d \u201cproactively takes tasks off your plate,\u201d and can \u201cmake purchases, generate images, create documents, and connect with your favorite apps and services.\u201d The macOS app (curiously, there\u2019s no Windows version) also works with a user\u2019s WhatsApp, email, calendar, and social media accounts. When a task requires a tool that doesn\u2019t exist, Muse creates one on the fly.<\/p>\n

Meta doth hype Muse security too much<\/h2>\n

Of course, for Muse to do any of these things, users must first give it access to their accounts. This includes authenticating the assistant to each service and, because the app runs on macOS, giving it permissions to a broad range of operating system-restricted device resources like writing files to disk, accessing the mic and camera, and monitoring location and calendars. Apple has spent years developing these defenses to prevent installed apps or commands entered into the terminal from accessing these resources, clearly because the company considers them a security threat. Muse completely undoes these default measures.<\/p>\n
