The DeepSeek app, which recently surpassed ChatGPT on Apple’s App Store, has been found to transmit user data to Chinese servers without encryption due to security flaws. According to research by NowSecure, the app disables Apple’s internal security system (ATS) and transfers data over the internet without encryption.

Experts warn that while individual data points may not be highly sensitive, aggregating them could reveal users’ identities. Additionally, DeepSeek uses the 3DES encryption algorithm, which is considered weak and insecure.

This issue has raised privacy concerns, as the collected data could potentially be used for espionage. As a result, users are advised to avoid entering personal information into the app. Furthermore, the Android version of DeepSeek does not have a high-security level either, and users should exercise caution when using it.
