In this report, we analyze the Windows, Android, and iOS versions of Tencent’s Sogou Input Method, the most popular Chinese-language input method in China. Our analysis found serious vulnerabilities in the app’s custom encryption system and how it encrypts sensitive data. These vulnerabilities could allow a network eavesdropper to decrypt sensitive communications sent by the app, including revealing all keystrokes being typed by the user. Following our disclosure of these vulnerabilities, Sogou released updated versions of the app that identified all of the issues we disclosed.
Vulnerabilities in Sogou Keyboard encryption expose keypresses to network eavesdropping.
Any data you submit to Google is stored and analysed. That’s different from sending keystrokes as they happen though.
I’m all for criticising invasive data use and collection which Google is definitely guilty of. It’s not the same as keylogging though which is not just a privacy concern but a pretty serious security one as well. Also we have actual evidence here of Tencent doing this which makes a difference to me at least.
It sends whole words instead!
