“Please do not make it public”: Vulnerabilities in Sogou Keyboard encryption expose keypresses to network eavesdropping
- We analyzed Tencent’s Sogou Input Method, which, with over 450 million monthly active users, is the most popular Chinese input method in China. Analyzing the Windows, Android, and iOS versions of the software, we discovered troubling vulnerabilities in Sogou Input Method’s custom-designed “EncryptWall” encryption system and in how it encrypts sensitive data. We found that network transmissions containing sensitive data such as those containing users’ keystrokes are decipherable by a network eavesdropper, revealing what users are typing as they type. We disclosed these vulnerabilities to Sogou developers, who released fixed versions of the affected software as of July 20, 2023 (Windows version 13.7, Android version 11.26, and iOS version 11.25). These findings underscore the importance for software developers in China to use well-supported encryption implementations such as TLS instead of attempting to custom design their own.
