Meta Muse Exposes Users' Personal, Business Secrets When They Share Conversations

2 weeks 4 days ago
Security researchers say Meta's Muse AI assistant exposed thousands of users' shared conversations because conversation titles were placed in subdomains that could be discovered through public DNS records. Meta has since suspended the sharing feature while it considers making changes. Ars Technica reports: Like many online services, Muse has allowed users to share searches, conversations, images, and similar content with other people. Such share features usually involve clicking an option to create a unique URL that anyone can use to load a page hosting the content. To keep potentially sensitive information from being accessible to unintended people, the URLs typically contain a long sequence of text that can't be easily guessed. Muse, which Meta CEO Mark Zuckerberg said last month was "built from the ground up for privacy and security," seems to take the same precautions. But a central design decision for constructing URLs has made the links easy to discover. As a result, researchers from security firm Claroc said they were able to enumerate 6,800 links Muse users created for sharing conversations with others. After opening a few hundred of them, the researchers found information that was clearly not intended to be publicly available... [...]. "If you had asked us beforehand, we would have guessed that gathering these would take real effort," the researchers wrote. "It took one query." [...] The easiest way to discover the URLs is to perform a passive DNS search through one of many available commercial services. Passive DNS records store the historical resolution of domain names to IP addresses, as well as nameserver, and mail-server records over time. Passive DNS systems typically collect DNS responses from sensors positioned at recursive DNS resolvers or other infrastructure. A passive DNS record is generally created when a monitoring system observes a DNS response. In the case here, once the intended party clicks on the share link, the DNS information is recorded in a searchable database. Claroc researchers were able to discover the Muse share links because all of them use the domain name cf.metaaiusercontent.com. Discovery is further made easy by the decision to add the conversation name to the URL, along with a long string of text. Simplified examples of such links are home-sale-budget-9f21c8a3.cf.metaaiusercontent.com, q3-revenue-review-7b1e42f0.cf.metaaiusercontent.com, and loan-application-draft-a4c9e2.cf.metaaiusercontent.com. It's this last design decision, putting the conversation title in the subdomain rather than in the URL path, that makes public discovery possible.

Omarchy 4.0.5 Released With Better NVIDIA Laptop Support

The Omarchy project has released Omarchy 4.0.5, introducing a substantial collection of hardware compatibility improvements, desktop performance optimizations, security fixes, and package updates for the Arch Linux-based operating system. Released on October 18, 2026, the update focuses on refining the existing desktop experience while preparing the distribution for its next major feature release.

Among the most important changes are improved NVIDIA hybrid graphics support for laptops, an updated Linux 7.2.8 kernel featuring the BORE scheduler, and compatibility improvements for Qt 6.12. The release also resolves boot-related black screens, fixes audio problems affecting certain Dell and USB speaker configurations, corrects Steam graphics driver selection, and improves the reliability of several desktop utilities.

Although version 4.0.5 is primarily a maintenance release, its improvements extend across many of the components that determine how smoothly a Linux desktop operates. From faster application launches and more responsive desktop panels to stronger security defaults and more reliable hardware detection, the update demonstrates Omarchy's continued emphasis on delivering a preconfigured Linux environment that requires relatively little manual setup.

Omarchy Continues Refining Its Arch Linux Desktop Experience

Omarchy is an opinionated Arch Linux-based distribution designed to provide a ready-to-use development and desktop environment built around the Hyprland Wayland compositor. Rather than presenting users with a minimal installation that requires extensive customization, Omarchy combines a carefully selected collection of applications, themes, keyboard shortcuts, and system configurations into a cohesive desktop experience.

The distribution has attracted attention among developers and experienced Linux users who appreciate keyboard-driven workflows, tiling window management, and the flexibility of Arch Linux without necessarily wanting to configure every component manually. Its desktop environment emphasizes efficient navigation, integrated development tools, and a consistent visual design, while retaining access to Arch's extensive software repositories.

Version 4.0.5 continues that approach by concentrating on problems that can interrupt everyday workflows. The release improves hardware compatibility, corrects regressions introduced by newer software packages, and reduces unnecessary delays in common desktop operations. Rather than introducing a dramatic redesign, the developers have focused on making the existing environment more predictable and responsive.
