Chinese Keyboard App Vulnerabilities Explained

We analyzed third-party keyboard apps Tencent QQ, Baidu, and iFlytek, on the Android, iOS, and Windows platforms. Along with Tencent Sogou, they comprise over 95% of the market share for third-party keyboard apps in China. This is an FAQ for the full report titled “The not-so-silent type: Vulnerabilities across keyboard apps reveal keystrokes to network eavesdroppers.”

The not-so-silent type: Vulnerabilities across keyboard apps reveal keystrokes to network eavesdroppers

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. Our analysis found that eight of the nine apps identified contained vulnerabilities that could be exploited to completely reveal the contents of users’ keystrokes in transit. 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.
