According to Foresight News, a tweet from Shen Yu suggests that cloud input methods used by up to a billion users may pose a risk of leaking input content. Analysis indicates that severe vulnerabilities exist in input method software from eight out of nine manufacturers. Some manufacturers have not even encrypted user input content, further exacerbating the risk. These vulnerabilities could potentially affect up to a billion users.
If users have used these cloud input methods to input mnemonic words or other sensitive information, it is recommended to immediately update the input method software and operating system they are using. This is a crucial step in mitigating the risk of data leaks and ensuring the security of user information.
