Former Meta security chief Alex Stamos called it “totally insane” to hand over personal data to Meta’s AI agent Muse, Business Insider reported. Muse encourages users to provide email logins and credit card information and can crawl through years of personal instant messages and access entire email inboxes, including exchanges with exes and passport numbers. On Alex Kantrowitz’s “Big Technology Podcast,” Stamos said some users hand over their password vaults, effectively giving Muse control over their entire digital lives. He also discussed viral personal AI assistant startup Instinct, founded by a 23-year-old research scientist months ago, which raised $1 billion in a September funding round and develops agents that autonomously complete day-to-day tasks; Stamos said such agents must break security measures by definition and that Instinct figured out ways to defeat automated bot detection mechanisms. Meta maintains on its website that Muse is safe because it runs on a virtual machine that is “isolated so no one else’s agent can access it,” but admitted “no automated system is perfect” and advised users to “review Muse’s activity and only grant the access you’re comfortable with.” Security researchers have already discovered vulnerabilities that could give hackers access to sensitive personal data, as The Information reported in September, causing Meta to bolster its defenses; last month, researchers once again identified other ways attackers can expose sensitive information when users share message exchanges through web links, per Ars Technica.
