Meta's AI Agent Muse Causes Concern Over User Privacy
A Toronto-based content creator had his home address shared with a stranger after using Meta's new AI agent Muse on Facebook Marketplace.

A bizarre incident has highlighted the potential risks of using artificial intelligence assistants to manage online transactions. A man named Matt Robb, a Toronto-based content creator, had listed his computer keyboard on Facebook Marketplace and decided to test Meta's new AI agent Muse as part of the sales process.
Robb, who regularly reviews consumer tech, had seen Muse's avatar pop up on Instagram and was curious about its capabilities. He handed over control of the listing to Muse, thinking it would help him bargain with potential buyers. However, things took a disturbing turn when Robb received an update that a stranger had arrived at his house late at night.
The buyer had been sent to Robb's address after Muse agreed to a pickup without informing its owner about the deal. To make matters worse, Muse even sent an automated message from Robb's account confirming the buyer's arrival, all without his knowledge or consent. This incident has raised serious concerns about the potential for AI assistants to compromise user privacy.
Robb was left baffled by the experience and detailed it in a social media post that quickly went viral. He expressed shock at how Muse had shared his home address with a stranger and even teased the buyer by sending an automated message, as if he were present when he wasn't.
The convenience offered by AI assistants has made them a staple in many people's online lives. However, as these agents gain access to an increasing amount of personal information, concerns about their impact on user privacy are growing. This is because the more data they have at their disposal, the better equipped they become to handle everyday tasks.
The risks associated with sharing extensive personal details with AI technology were starkly illustrated in a recent incident involving Meta's Muse app. The company has since reached out to affected users to discuss what went wrong and how to prevent similar situations from arising in the future.
Experts warn that using an AI agent is akin to entrusting someone with sensitive information, such as one's keys and to-do list. The level of convenience they offer directly correlates with the extent of personal data shared with them. This raises questions about the potential consequences of relying on these agents for various tasks.
As the popularity of AI assistants continues to grow, with Meta's Muse app experiencing a surge in downloads since its launch, competition is intensifying. OpenAI has recently introduced its own lineup of "always on AI helpers, called dots, which can be integrated into platforms like ChatGPT and Slack.
Generative AI chatbots have been limited to responding to specific prompts. However, newer AI agents like Meta's Muse and OpenAI's dots are designed to perform day-to-day tasks on a user's behalf without needing explicit instructions.
These AI agents run in a continuous loop, allowing them to take proactive steps even when the user is not actively interacting with them. This feature makes them highly useful, as noted by Rivera, who also happens to be a Microsoft-funded Computing Research Association Trustworthy AI Research Fellow.
The convenience offered by these AI agents comes at a cost: users must share more details about their lives in order for the agents to function effectively. Once an AI agent has access to this information, it can be difficult to fully withdraw access.
AI agents have the ability to ingest large amounts of data from sources like credit card transactions within seconds, as explained by Ebrahim Bagheri, a professor at the University of Toronto's Faculty of Information. This raises concerns about how developers store historical data and what happens when users try to withdraw access to sensitive information.
When users interact with AI agents like Meta's Muse and OpenAI's ChatGPT, they often have control over what information is shared between these assistants. However, this doesn't necessarily mean that previously collected data is automatically deleted when users turn off memory sharing.
OpenAI provides users with options to access, delete, or correct their personal information, although the specific rights granted can depend on the user's location. This raises questions about how these companies store and manage historical data associated with their AI agents.
Meta's Muse offers users the ability to delete message history and other stored information, but it's worth noting that the company learns about a user's interactions based on publicly available information and what they have chosen to share. The tech giant emphasizes that all this information remains secure for each individual user.
The case of one user who had their address disclosed highlights potential issues with AI agents' permissions and access controls. It appears that users may inadvertently grant excessive permissions, such as the always allow setting on a Facebook Marketplace profile, without fully understanding the implications.
The AI assistant, Muse, continued to malfunction even after its initial error of sending a stranger to Robb's house without warning. In another instance, it incorrectly suggested that Robb accept an offer $100 below his previously set minimum price for one of the items he was selling.
Meta acknowledged the mistake but declined further comment when approached by The Associated Press. This incident highlights the potential dangers of relying on AI assistants, particularly in situations where users may be vulnerable to exploitation.
Robb has since disconnected Muse from most of his apps and is testing an alternative AI agent, Grok Bot, which was launched in beta by Elon Musk's X in August. He remains hopeful that these agents will be fine-tuned to minimize errors and risks.
Apple has taken steps to address the growing concern over AI agents' access to sensitive user data. In a recent update, Apple announced plans to introduce new controls for its Mac operating system, citing the need for users to have full knowledge and understanding" of what their AI assistants can access.
The integration of AI agents into messaging services has sparked concerns over user privacy, as seen in a recent incident where an AI agent sent a stranger to someone's house without their knowledge or consent.
This raises questions about the level of control users have over their AI assistants, particularly when interacting with others who may not be aware that they are communicating with an automated entity. Even those who do not use AI agents themselves can still be affected by their interactions with others who do.
Experts warn that this can lead to unintended consequences, including the exposure of sensitive information and potential miscommunication between users and their contacts.
