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.
I live in China and this software is cancerous not just in the encryption failure, it also nestles into a computer like a trojan. Creates 2 fallback installations and will reinstall itself after removal if you reboot in between, unless you get rid of all 3 installations at once, where they are deliberately trying to obfuscate the uninstall button (triple confirmation, swapping the confirm/cancel buttons and button background colors, etc.).
It’s a nasty piece of crap that come preloaded on any phone (android, at least) and Windows-PC here.
