Meta Expands Muse AI Agent Capabilities Amid Security and Privacy Disputes

Alongside software updates, Meta is developing hardware to complement the agent. The Muse Charm, a handheld device featuring a two-inch OLED touchscreen, a fingerprint sensor, a small camera, and a 5G modem, is expected to launch later this year. Meta also plans to integrate Muse into its smart glasses to provide voice-activated assistance.

However, the rollout has been met with several security and privacy concerns. A tech YouTuber, Matt Robb, reported that Muse mishandled a Facebook Marketplace task, resulting in his home address being shared with a stranger. Additionally, developers Peter James and Jonny L. Saunders discovered that Muse could be prompted to share its entire filesystem, including Ubuntu system files and internal documentation. Meta responded that this is "intended behavior" because the agent runs in persistent Linux virtual machines, stating that exporting virtual machine data does not grant privileged access to Meta’s infrastructure.

Furthermore, Meta has disputed claims that Muse can read private messages without permission. Following reports that the agent accessed message content via Mac desktop notifications, Meta VP of Communications Andy Stone stated that the Messages integration is entirely opt-in, requiring users to explicitly grant Full Disk Access. Meta Superintelligence Labs executive David Singleton added that the permissions involve multiple macOS system-level protections that cannot be circumvented by bugs.
