Meta's Muse AI Chat Security Flaw Exposes 6,800 Conversations

Security researchers at Claroc discovered a critical vulnerability in Meta's AI agent Muse, exposing over 6,800 publicly accessible links to shared conversations. These included confidential corporate data such as revenue analyses, loan applications, and internal HR information. The flaw stemmed from Muse's sharing feature, where conversation links could be found via public DNS records, bypassing the intended obscurity of random identifiers. After being alerted by Ars Technica on October 20, 2026, Meta temporarily disabled the sharing functionality. The incident highlights growing concerns about data privacy in AI agent platforms, especially as Meta expands Muse for business use. Meanwhile, Muse has seen explosive growth, with 10.9 million global downloads in 40 days, driven by Meta's marketing push and integration across its app ecosystem.

Meta's AI Companion Muse Hits 10M U.S. Downloads in 40 Days

Meta's AI companion Muse has surpassed 10 million U.S. downloads within its first 40 days, making it the fastest-growing app since Threads. According to Sensor Tower, it reached about 10.9 million global downloads, with 10.2 million from the U.S., accounting for 94% of total downloads. Meta significantly boosted its visibility by allocating 39% of its ad budget to Muse in October, up from 23% in September, making it a top advertiser. Muse shows strong retention, with a 30% 7-day retention rate in the U.S., outperforming rivals like ChatGPT, Grok, and Claude, though it loses more users after the first day.
