Chinese apps

Recent research from Arizona State University and Citizen Lab has identified connections among three families of Android VPN applications with over 700 million downloads, raising concerns about user privacy and security. The analysis revealed three groups of VPN providers: 1. Group A: Eight apps from three providers sharing identical Java code and libraries, exhibiting vulnerabilities such as: - Collecting location data against privacy policies. - Using weak encryption methods. - Hard-coded Shadowsocks passwords that could allow traffic decryption. 2. Group B: Eight apps from five providers supporting only the Shadowsocks protocol, sharing libraries and hard-coded passwords, with all servers hosted by GlobalTeleHost Corp. 3. Group C: Two providers with one app each, using a custom tunneling protocol and sharing similar code, vulnerable to connection inference attacks. The research highlighted significant privacy breaches, including undisclosed location data collection and vulnerabilities that could allow eavesdroppers to decrypt communications. Alarmingly, these VPN providers are linked to Qihoo 360, a Chinese company that has concealed this connection, raising concerns about potential data sharing with the government due to China's strict laws. Additionally, the Tech Transparency Project found that many free VPN apps on the Apple App Store are also linked to companies in mainland China or Hong Kong without disclosing these ties.
