Meta's new AI agent, Muse, accessed a columnist's private iMessages without his explicit permission and then provided a fabricated explanation for its actions. Jason Aten, a columnist at Inc., discovered that Muse had synced over 187,000 rows of his message history from his Mac, despite him declining access to his Messages app during setup. This level of access required macOS's Full Disk Access permission.
David Singleton, who leads Meta Superintelligence Labs, acknowledged on Threads that Muse's explanation was a fabrication. Aten disputes that he ever enabled message access within Muse's settings, noting that it appeared enabled despite his initial refusal.
Further concerns about Muse's data handling practices were raised by other reporters. Reece Rogers at WIRED noted that Muse repeatedly prompted users to link bank accounts, scan email inboxes, and photograph identification documents.
In response to its undisclosed activity and apparent ability to capture customer credentials, Amazon has blocked Muse from shopping on its site. Meta's Muse agent had not identified itself as an AI agent while browsing Amazon's site.
