Even Silent Apps Speak: Privacy Risks of Platform-Level Traffic in Meta VR

Overview This repository contains the platform-level traffic dataset and the analysis code used in the submission. The dataset contains platform-level traffic collected from Meta Quest devices under controlled experimental conditions. Dataset Structure Due to storage limitations, only a subset of the dataset is released. A random sample of 30 pcap files per application is included Each application's traces are compressed into: <app-name>.zip Collection Summary Devices: Meta Quest 2, Quest 3, and Quest Pro (multiple units across two environments) Tools: adb, tcpdump, automated shell scripts Capture Duration: 180 seconds per session Collection Periods: VR app data from April–September 2024 Dataset Size: 84,492 pcap files (≈ 600 GB) for VR apps Data Characteristics Metadata: Each file labeled with app, device ID (1-8), headset model (Quest 2, 3, or Pro), and timestamp Data Filtering: Only platform-level traffic exchanged with Meta's infrastructure (AS32934) is included. Local network setup packets (e.g., DHCP) are removed. Corrupted or incomplete sessions are excluded. Ethical and Privacy Considerations All devices were configured with privacy settings enabled and data sharing disabled No user-generated content or application payloads were inspected All traffic remains encrypted, and only metadata (e.g., packet size, timing) is used
