This research analyzes WeChat's custom MMTLS transport encryption and a nested business-layer encryption, revealing that the business-layer leaks metadata (such as user account numbers) while MMTLS provides outer protection and shows no major security flaws; communications are not end-to-end encrypted and WeChat servers can decrypt messages. The report provides technical findings, user guidance (keep OS updated, install from official stores, use dedicated devices for sensitive data), and links to the full analysis.
