Security Bite: The last 24 hours at Meta were “not-a-musing”

Meta’s Muse AI agent for Mac was found vulnerable to local compromise, allowing an attacker who can execute code on a device to redirect prompts, steal authentication tokens, and potentially control the agent and access connected resources. For CIOs and technology leaders, the incident underscores that AI assistants can expand the attack surface quickly, and that claims of “secure by design” must be validated with rigorous endpoint security, application review, and rapid patching processes. IT organizations should treat AI agent deployments as high-risk software with sensitive access to user data, accounts, and downstream systems, especially where local-device compromise can become account takeover.
