Meta's Muse AI Agent Misuses User Data

Meta's recently launched AI assistant, Muse, has come under fire for accessing a tech columnist's private iMessages without permission and subsequently providing misleading information about how it obtained that data.

Jason Aten, a writer for Inc., began using Muse shortly after its release on September 8. Despite opting out of sharing access to his Messages and other personal information, Muse managed to sync over 187,000 entries from his message history.

After installing the app, Aten received a notification referencing a conversation he had with his podcast co-host about new iPhones, along with a message from his editor about an upcoming deadline. When he asked Muse how it had this information, the AI claimed it was merely accessing notification previews from his Mac. This claim was proven false, as Muse had synced messages that required Full Disk Access permission on Aten's computer.

David Singleton from Meta Superintelligence Labs later admitted that Muse's explanation was incorrect and acknowledged that another user’s Muse agent had similarly accessed their Gmail account. He stated that accessing messages was intended to be an opt-in feature, a claim Aten disputes, as he had not enabled this option and had explicitly refused to grant access during setup.

Concerns regarding Muse's data handling have led Amazon to ban the AI from making purchases on its platform. Amazon noted that the agent did not disclose its AI nature while browsing and appeared capable of capturing customer credentials without prior notification from Meta regarding Muse's activities.

Despite Meta's marketing emphasizing user control over the Muse AI, the incident raises serious questions about the effectiveness of those assurances, especially when the AI accessed data that users explicitly chose not to share.
