It seems that even its own employees are worried. Before launching the AI agent, engineers found a security vulnerability that could've allowed Muse users to break into Meta's own databases and services and access other people's sensitive information, [*404 Media* reports](). Such a hack would be disastrous. Meta asks users to let Muse control everything from their [bank accounts to their emails](). The vulnerability was fixed in a "mad dash" before the product was released, but some employees are apparently convinced that the threat hasn't gone away. "Many senior engineers believe it's inevitable we're going to have a massive data breach as a result of Hatch," a Meta source told *404*, referring to Muse's internal nickname. To allow it to perform tasks that require a computer, like booking flights or shopping for groceries, Muse agents run on a kernel-based virtual machine, or KVM, which is supposed to be isolated from the rest of Meta's infrastructure. But barely two weeks before Muse launched, engineers rushed to fix a "sudden spike in reported KVM escapes," according to an internal post by Meta executives, or instances in which a Muse agent sneaks out of its virtual machine and starts interacting with other Meta systems — or even other users' virtual machines. One of these vulnerabilities could've allowed an attacker using a normal Muse account to access the sensitive data in Meta databases. According to the reporting, concern around the vulnerability was serious enough that it even landed on CEO Mark Zuckerberg's desk, with several security teams working day and night to fix it. But the Meta source sounded dubious about whether the fixes were robust enough, calling them "half-baked protections being rushed out to enable the launch." KVM escapes are considered so dangerous that Meta is offering a $300,000 bounty to anyone who finds a vulnerability that can cause one to happen. On its bug bounty page, Meta lays out the stakes in stark terms. "Because a Muse agent holds a user's most sensitive data and can act on their behalf, we treat compromise of that boundary as a first-class security risk," the company [says](), as pointed out by *404*. Experts say flaws in how Meta walls off its agent that could lead to such an escape happening. "This issue is that Hatch makes the virtualization boundary a production security boundary," security researcher Patrick Wardle told *404*. " I feel like this design is inherently risky, particularly risky as AI lowers the cost of finding, analyzing, and exploiting exactly these kinds of complex virtualization vulnerabilities." The panic behind the scenes over the KVM escape comes at a pivotal moment over the current expectations around AI tools and their actual capabilities. For months, top AI companies have publicly fretted about how their powerful agents have [broken containment and launched cyberattacks on other companies and government websites](). We're now seeing how dangerous the tech can be amid the push to have AI agents control our personal lives. **More on AI:** [*Man Says Meta’s Muse AI Gave His Home Address Out to Strangers*]() ## Author At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled. ### Author social links [Bluesky]()
