A ▲ +3.3% - Agilent Technologies, Inc. $A zero-day has been released for Muse, Meta's new AI agent, and a Meta AI security engineering manager who left the company this month says he would never use it, citing security and privacy concerns. He was reacting to the zero-day a researcher posted, which lets malware hijack Muse for Mac. A local process with no special privileges can change an undocumented Muse setting and send dictated prompts to an attacker's server. This could allow for prompt capture, prompt injection and theft of Muse's authentication material. It can also get access to whatever the user has let Muse access, including files, Mail, Messages, Calendar and Notes. -- ICD A rose 3.3% today, though the headline references a security vulnerability in Meta's Muse AI agent for Mac—not Agilent Technologies. The zero-day allows malware to hijack Muse and potentially capture sensitive user data and authentication credentials. The stock movement appears unrelated to this cybersecurity disclosure. 21-SEP-2026 03:11 PM ET
