According to experts, around 450 million users worldwide may have been affected by the vulnerability. The problem is that the keyboard records keystrokes, and without encryption, there is no difficulty understanding what a person is typing, including logins and passwords. Moreover, all the information went to the servers of the Chinese IT giant Tencent.
Eventually Tencent acknowledged the problem. Later, after long negotiations with The Citizen Lab, Sogou developers also noticed the vulnerability and later released updates for all versions of the app.
“By analyzing Windows, Android and iOS versions, we found troubling vulnerabilities in the specially designed EncryptWall encryption system and how it encrypts sensitive data,” the experts said.
