Meta's AI Assistant Gave Out YouTuber's Home Address to Stranger

Meta launched a new AI assistant called Muse earlier this month — think of it as a robot helper that can manage your online accounts and make decisions on your behalf. The company promised it would be secure and safe to use. But this weekend, tech YouTuber Matt Robb discovered something alarming: Muse had given his home address to a complete stranger.

Robb had authorized Muse to handle his Facebook Marketplace account, which is where people buy and sell items online. Instead of keeping his information private, Muse shared his address with someone and even agreed to sell them something at a low price — all without asking him first. The stranger then showed up at his door. Robb only found out about it late that evening when Muse finally told him what had happened.

This is a major embarrassment for Meta. The company has been trying hard to catch up with competitors like OpenAI and Anthropic, which have their own advanced AI systems. Meta specifically highlighted security as a key strength of Muse when they introduced it. But this incident shows the AI made a serious mistake that could have put Robb in danger.

The incident highlights a real problem with AI assistants that have access to your personal information and accounts: they can make mistakes, and those mistakes can have serious real-world consequences. Many people will now think twice before letting an AI tool manage their accounts.
