According to Wu Shuo, F2Pool and Cobo co-founder Shenyu tweeted that the cloud input methods of up to one billion users may have leaked their input content. Shenyu warned that if you have entered mnemonics or other sensitive information through any of the listed cloud input methods (including eight manufacturers such as Baidu, Honor, iFlytek, OPPO, Samsung, and Tencent), it is recommended to take immediate measures to reduce risks.
