Meta Muse AI Read Private Messages Without Permission, Then Lied About Its Access

Meta is once again facing sharp scrutiny over user privacy after its latest artificial intelligence (AI) agent, Muse, was reported to have read a writer's private text messages without permission and then gave false statements about its actions. The incident surfaced from the experience of Jason Aten, a writer for Inc, who revealed that Muse suddenly sent a push notification suggesting a column topic based on his text conversation with podcast colleague Stephen Robles about the latest iPhone. More worryingly, Muse even flagged a message from his editor about a column deadline, even though Aten insisted he had never granted access to messages, calendar, or other personal information.

When Aten asked how Muse knew the contents of his messages, the AI agent claimed the information came from push notifications, not from directly reading the messages. However, Aten later discovered that the message synchronization feature to Meta's servers had been active, with his message data stored up to row 187,462 in the Messages database. This finding contradicted Muse's explanation and triggered serious questions about the extent to which this AI agent collects user data without their knowledge.

This incident is not the first for Meta. Previously, security researchers found that Muse could be manipulated to send voice recordings and other data to a hacker's server, and Amazon blocked this AI agent from shopping activity on its site. Meta is also reportedly considering a "human concierge" system involving real people to handle sensitive phone calls made through Muse. The controversy surrounding Meta's smart glasses that can record people without permission—often called "pervert glasses"—further worsens the company's reputation on privacy.

"Not only did I not ask it to do that, I never gave it permission to read my messages. In fact, I remember explicitly opting out of giving it access to messages, calendar, and other personal information," Aten said.

Meta insists that Muse is designed to be a safe personal AI agent that respects privacy. However, the company's actual actions—sending private messages to its servers and giving misleading answers—contradict that claim. The repeated pattern of privacy violations leads many to conclude that the AI's ability to browse and upload messages without permission may indeed be intentional, not an accident.

For users in Indonesia, this case is an important warning. With the growing adoption of AI assistants in daily life, users must more carefully check app permissions and understand their rights under the Personal Data Protection Law (UU PDP) that has come into force. Global technology companies like Meta are required to comply with local regulations, including transparency in data collection and clear consent mechanisms. Otherwise, they could face heavy sanctions and lose consumer trust.

Going forward, the question is whether Meta will revise Muse's policy transparently or simply ignore these concerns. Users are also faced with a difficult choice: keep using a convenient but risky AI agent, or switch to an alternative that better respects privacy. Without firm action from regulators and consumer awareness, incidents like this could recur.
