The Citizen Lab’s Mona Wang, Jeffrey Knockel, and Zoë Reichert, in collaboration with Princeton researchers Prateek Mittal and Jonathan Mayer, co-authored a new paper on the network security of Android apps. Their research found that a large portion of popular Chinese apps use broken proprietary network protocols instead of TLS.

The paper, titled “WireWatch: Measuring the security of proprietary network encryption in the global Android ecosystem,” will be presented by Wang at the 2025 IEEE Symposium on May 14, 2025. Register here.
