To address the security vulnerabilities associated with disabling App Transport Security (ATS) in DeepSeek, several alternative security measures could have been implemented:
1. Enable and Enforce ATS: The most straightforward alternative is to enable ATS and ensure that all communications between the app and its backend services use HTTPS. This would prevent the app from sending sensitive data over unencrypted channels, significantly reducing the risk of man-in-the-middle (MitM) attacks[2][4].
2. Implement End-to-End Encryption (E2EE): DeepSeek could have implemented E2EE to protect user data from interception and manipulation. This involves encrypting data on the client-side before it is transmitted to the server, ensuring that only the intended recipient can decrypt it. This approach would safeguard sensitive information even if the data is intercepted during transmission[6].
3. Use Stronger Encryption Algorithms: Instead of using outdated encryption algorithms like 3DES, DeepSeek could have adopted more secure and modern encryption standards such as AES-256. This would make it much harder for attackers to decrypt and access sensitive data[4][6].
4. Certificate Pinning: Implementing proper certificate pinning would help prevent attackers from using fake certificates to intercept traffic. This involves embedding the expected SSL/TLS certificate or public key in the app, ensuring that only communications with the expected certificate are trusted[6].
5. Mobile App Attestation: Using a mobile app attestation solution like Approov could ensure that only genuine, unmodified instances of the app can connect to backend APIs. This would prevent tampered or repackaged apps from making unauthorized API requests and stealing user data[2].
6. Secure Data Storage: DeepSeek should ensure that all data stored on the device or transmitted to servers is encrypted and protected against unauthorized access. This includes using secure storage mechanisms for sensitive data such as passwords and encryption keys[4][6].
7. Regular Security Audits: Conducting regular security audits and penetration testing would help identify vulnerabilities early on, allowing DeepSeek to address them before they become major issues. This proactive approach would enhance the overall security posture of the app[2][4].
By implementing these measures, DeepSeek could significantly improve its security and protect user data more effectively, reducing the risks associated with disabling ATS and other security vulnerabilities.
