Insecure Data Transmission, Storage, and Extensive Collection

The DeepSeek iOS app has multiple critical security and privacy flaws that jeopardize sensitive user data. Our analysis found the app transmits usernames, passwords, encryption keys, and other private information over unencrypted channels, making it vulnerable to interception. It also uses weak, outdated 3DES encryption with hardcoded keys that are easily extractable. User data is stored insecurely on devices in cached databases, increasing the risk of unauthorized access if a device is compromised.

DeepSeek extensively collects data on users and their devices that can be used for tracking and de-anonymization. This includes:

1. Device name, often containing the user's real name
2. IP address
3. Advertising IDs
4. Operating system version
5. Language settings
6. Color schemes

This data is transmitted to servers belonging to ByteDance and governed by laws of the People's Republic of China, raising major privacy and compliance concerns. The aggregation of data points collected by the DeepSeek app and other sources enables precise identification of individual users, even without directly using their name.

1. Unencrypted Transmission of Sensitive Data

The DeepSeek iOS app sends usernames, passwords, encryption keys and other private data over the internet with no encryption. This exposes the information to interception and modification by attackers, especially on public Wi-Fi networks. Even when using a cellular connection, recent breaches of major US mobile carriers by Chinese hacking groups puts this data at risk of surveillance and misuse.

Apple provides default protections to prevent apps from sending sensitive data insecurely, but DeepSeek deliberately disabled this App Transport Security feature globally. As a result, private user information is transmitted in plain text that anyone on the network can read.

2. Insecure Encryption with Hardcoded Keys

DeepSeek claims to encrypt some user data, but does so in a highly insecure way. The app uses the deprecated and weak Triple DES (3DES) algorithm and hardcodes the encryption keys directly into the app. It also reuses initialization vectors, further weakening the encryption.

This means anyone can easily extract the encryption keys from the app and decrypt private data. Hardcoding keys is an extremely poor security practice that exposes DeepSeek's lack of basic data protection competencies.

3. Sensitive Data Stored in Cached Databases on Devices

The DeepSeek app was found to be caching sensitive data like usernames, passwords, and encryption keys in databases on user devices. While protected when the device is locked, this data can be recovered and abused if an attacker gains physical access to an unlocked device.

Cached data like this should be avoided for highly sensitive information. However, DeepSeek failed to disable caching when transmitting private user data, increasing the risk of exposure through a lost or stolen device.

In the next section, we'll take a closer look at DeepSeek's extensive collection of user data and how it puts privacy at risk by enabling individual identification and tracking. The app collects dozens of data points on each user that can be combined with information from other sources to de-anonymize and surveil users without their awareness.

DeepSeek Collects Vast Amounts of User Data

The DeepSeek iOS app gathers an alarming amount of data on its users that, when combined, can precisely identify individuals even without using their name directly. This includes device names that often contain the owner's real name, IP addresses, advertising IDs, operating system versions, language settings, and color schemes. Collecting such an extensive array of data points enables DeepSeek to create unique digital fingerprints of users that can be used for tracking and de-anonymization.

Even more concerning, all this sensitive user data is transmitted to servers belonging to ByteDance and other Chinese companies like Volcengine. This raises major red flags about the privacy and security of the information, as it becomes subject to China's legal system and the broad data access it grants to the government. With U.S. user data being stored and processed in China, it could be obtained by Chinese authorities for surveillance and espionage purposes.

1. DeepSeek's Massive Collection of User and Device Data

When you use the DeepSeek iOS app, it vacuums up a trove of data about you and your device. This includes your device name, IP address, advertising ID, operating system version, language settings, color schemes, and more. By gathering so many different data points, DeepSeek can piece together a unique "fingerprint" that identifies you as an individual user.

For example, your device name alone, like "John's iPhone", can reveal your real name to DeepSeek. Coupled with your IP address, this ties your identity to a specific location. Advertising IDs allow further tracking of your activity across other apps and websites. Even choices like your language settings and color schemes help distinguish you from other users. Aggregated together from the app and other sources, this data enables DeepSeek to figure out exactly who you are.

2. User Data Sent to ByteDance and Governed by Chinese Laws

The extensive data collected by the DeepSeek iOS app doesn't just stay on your device. It's transmitted to servers belonging to ByteDance and other Chinese companies like Volcengine. This means your private information is being sent to China, where it becomes subject to the country's legal system and cybersecurity laws.

Under China's legal framework, companies are required to share data with the government upon request. They must also store data locally and submit to security assessments. This raises major concerns that U.S. user data collected by DeepSeek could be accessed and leveraged by Chinese authorities for surveillance, espionage, or other nefarious purposes, with little recourse for users.

3. Broad Data Sharing Provisions in DeepSeek's Privacy Policy

DeepSeek's own privacy policy reveals the extent of data sharing that occurs. It states that user data is not only stored and processed in China, but can be shared with a wide range of third parties. This includes ByteDance, its subsidiaries, service providers, and other business partners.

The reasons given for this data sharing are vague and far-reaching - from supporting the app's operation to improving the user experience to "other purposes" disclosed in the privacy policy. With such broad language, it's unclear exactly who is getting access to DeepSeek user data and how it's being used. The privacy policy raises more questions than it answers about the safety of personal information collected by the app.

DeepSeek's extensive harvesting of user data that can precisely identify individuals, combined with its storage in China and broad sharing provisions, poses serious risks to the privacy and security of the app's users. In the next section, we'll look at steps you can take to mitigate these dangers when using DeepSeek.
