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.
What’s the deal with Android “keyboards”? Why is it just an app that you can install? And why can it have more functionality/permissions from the OS beyond just being a local keyboard? As an iOS user this is very bizarre and foreign to me.
I feel like every time the topic of Android keyboards (again, why is this a thing?) comes up it’s some kind of big spyware thing. Seems like most every app on Android and iOS is spyware anyway, of course.
