  • In this report, we examine cloud-based pinyin keyboard apps from nine vendors (Baidu, Honor, Huawei, iFlyTek, OPPO, Samsung, Tencent, Vivo, and Xiaomi) for vulnerabilities in how the apps transmit user keystrokes.

We estimate that up to one billion users could be vulnerable to having all of their keystrokes intercepted, constituting a tremendous risk to user security.
