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.
The Xzibit begins to compound itself. Soon there is so much whataboutism compressed into other instances of whataboutism that the singularity has formed. Faintly, all you can make out above the constantly repeating “Yo dawg, we heard…” is the whoosh of the empty air spinning around inside OP’s head. And suddenly, with a cacophonous roar there is nothing but silence. And then, triumphantly, a yellow sickle and hammer emblazon themselves against a red background as the Soviet National anthem plays. OP is at peace.
