TLDR:
- Eight out of nine Chinese character keyboard apps have vulnerabilities that allow eavesdropping
- Researchers from Citizen Lab uncovered exploitable vulnerabilities in popular Pinyin keyboard apps
Research conducted by Citizen Lab revealed that the majority of keyboard apps used for inputting Chinese characters on mobile devices are susceptible to passive eavesdropping attacks. These vulnerabilities pose risks to user data such as login credentials, financial information, and messages that are typically encrypted. The study focused on nine Pinyin apps from vendors like Baidu, Samsung, Huawei, and others, with all except Huawei found to be transmitting keystroke data to the cloud in a way that enables eavesdroppers to collect and read the data in clear text.
The scope of vulnerabilities found by Citizen Lab researchers highlights that up to 76% of keyboard app users in mainland China could be impacted by these weaknesses. The vulnerabilities were considered easy to exploit and did not require advanced technical skills. Methods of exploitation varied among different apps, with vulnerabilities identified in local and cloud-based components. The findings suggest that up to one billion users could be affected by these vulnerabilities, potentially enabling mass surveillance by various entities.
These vulnerabilities underscore the importance of addressing security issues in popular apps that handle sensitive user data. As mobile devices continue to play a crucial role in daily activities, ensuring the security and privacy of user information becomes paramount in safeguarding against potential exploitation and eavesdropping attacks.
