AI researcher exposes Meta's Muse assistant tracking personal social connections hourly

·8 views

In early October 2026, independent researcher Karan Joshi discovered Meta's AI assistant Muse maintains detailed files on people in users' social circles. The system compiles and refreshes personal information hourly from messages, photos, and past interactions without those individuals' consent. This revelation sparked debate about AI memory systems, contrasting Meta's transparency claims against privacy researchers' dossier concerns. Meanwhile, engineer Kevin Liao argued that current AI memory approaches using vector databases are flawed because they prioritize text similarity over accuracy. Liao proposed replacing such systems with structured documentation that agents and humans can review and update collaboratively.

New tool scrapes public Meetup event data from embedded cache, bypassing API restrictions

A tool called Meetup Events Scraper extracts public event data from Meetup.com without requiring login or API keys. It works by reading the Apollo GraphQL cache embedded in the public search page's HTML, which Next.js applications provide. This approach bypasses Meetup's official API, which is restricted to paying Pro subscribers. The service is offered on a pay-per-use basis, charging for each search run and per event retrieved.

Verify patches for critical NetScaler flaw CVE-2026-88772, advisories warn

Security agencies NCSC-NL and CERT-FR have issued advisories regarding the critical vulnerability CVE-2026-88772 in Citrix NetScaler ADC and Gateway devices. The flaw, which requires DTLS to be enabled for exploitation, was actively exploited before fixes were released. The fixed software builds are version 14.1-73.37 and later for the 14.1 branch. Organizations are urged to verify their patches across all systems, including failover units, and to preserve logs from the exposure period. Over 239,000 internet-facing Citrix NetScaler instances were identified in a recent scan.

Firebase Token Toolkit simplifies API testing by generating valid ID tokens

A new tool called Firebase Token Toolkit helps developers generate valid Firebase ID tokens for testing backend APIs. It bypasses the need for custom scripts by using a service account to create a custom token and exchange it via Google's authentication system. The resulting ID token is indistinguishable from one generated by a real client sign-in. The tool also assists with related tasks like managing custom claims and App Check tokens. It is a native application available for Linux, Windows, and macOS.

Study compares ten weight formats for Gemma 4 E2B on AMD MI300X hardware

A developer has conducted a performance comparison of ten different weight formats for serving the Gemma 4 E2B language model on an AMD Instinct MI300X GPU. The test used the vLLM serving framework, timing each format across various request counts and prompt lengths. Results showed FP8 format performed closest to the baseline BF16 format, while 4-bit formats were significantly slower. The fastest formats involve the most rounding of the model's original trained weights, presenting a trade-off between speed and precision. All test logs, reports, and scripts have been publicly released on GitHub.
