One Hidden Meta Muse Setting Could Let Attackers Turn the AI Assistant Into a Backdoor

What happened

Security researcher Patrick Wardle demonstrated a way malware already present on a Mac can hijack Meta’s Muse AI assistant. The exploit works by toggling a hidden setting to redirect audio input from the user’s microphone away from Meta’s servers to the attacker. This manipulation lets the attacker listen in and capture dictated prompts meant for the AI assistant without alerting the user.

The risk

Any malicious software with local access to the Mac can silently flip this switch and turn Muse into a backdoor. The attacker gains the same broad permissions the user granted the AI, including access to spoken input. Since the user triggers Muse manually by tapping the microphone, this redirection is hard to detect, making it an effective interception vector for sensitive voice commands or data.

Why it matters

This flaw weakens trust in AI assistants running locally with microphone access. It raises the bar on the sophistication attackers need because they must already have malware installed—but it forces operators to rethink assumptions about how AI apps handle permissions internally. Businesses and individuals rely on AI helpers for private tasks and commands. When that trust erodes, the risk of confidential data leaks spikes and defensive controls must tighten.

Who should pay attention

Mac users with Muse AI, security teams monitoring Mac endpoints, and app developers building AI assistants should take note. Operators need to understand that local malware can turn voice-controlled AI agents into covert listening posts. Security tooling and permissions management have to evolve to detect or block this kind of misuse.

What to watch next

Watch for Meta’s response and patches addressing this hidden setting vulnerability in Muse. Also track any reported exploit kits or malware variants that incorporate this bypass. Longer term, keep an eye on how AI assistant platforms improve permissions transparency and harden microphone input controls against stealthy redirection attacks.
