I conducted a fixed analysis of DeepSeek, a Chinese LLM chatbot, bybio.co utilizing variation 1.8.0 from the Google Play Store. The objective was to identify prospective security and privacy issues.

I have actually composed about DeepSeek formerly here.

Additional security and personal privacy concerns about DeepSeek have actually been raised.

The findings detailed in this report are based simply on fixed analysis. This implies that while the code exists within the app, there is no conclusive proof that all of it is executed in practice. Nonetheless, the presence of such code warrants examination, especially provided the growing concerns around data privacy, monitoring, the possible abuse of AI-driven applications, and cyber-espionage dynamics in between global powers.

Key Findings

Suspicious Data Handling & Exfiltration

- Hardcoded URLs direct data to external servers, raising concerns about user activity monitoring, such as to ByteDance “volce.com” endpoints. NowSecure recognizes these in the iPhone app the other day as well. - Bespoke file encryption and information obfuscation methods are present, with indications that they could be used to exfiltrate user details.

• The app contains hard-coded public keys, instead of depending on the user gadget’s chain of trust.
• UI interaction tracking catches detailed user habits without clear permission.
• WebView adjustment is present, which could permit for the app to gain access to personal external web browser information when links are opened. More details about WebView manipulations is here
  
  Device Fingerprinting & Tracking
  
  A substantial part of the analyzed code appears to concentrate on gathering device-specific details, which can be used for townshipmarket.co.za tracking and fingerprinting.
  
  - The app gathers numerous special device identifiers, consisting of UDID, Android ID, IMEI, IMSI, and provider details.
• System properties, set up packages, systemcheck-wiki.de and root detection systems suggest prospective anti-tampering measures. E.g. probes for the presence of Magisk, a tool that personal privacy supporters and security researchers use to root their Android devices.
• Geolocation and network profiling are present, suggesting possible tracking abilities and enabling or disabling of fingerprinting programs by area.
• Hardcoded device design lists suggest the application might act differently depending on the .
• Multiple vendor-specific services are utilized to draw out extra device details. E.g. if it can not identify the device through standard Android SIM lookup (due to the fact that permission was not granted), it tries producer particular extensions to access the exact same details.
  
  Potential Malware-Like Behavior
  
  While no definitive conclusions can be drawn without vibrant analysis, several observed behaviors align with recognized spyware and malware patterns:
  
  - The app uses reflection and UI overlays, which could facilitate unapproved screen capture or phishing attacks.
• SIM card details, identification numbers, and other device-specific data are aggregated for unidentified purposes.
• The app executes country-based gain access to constraints and “risk-device” detection, suggesting possible security mechanisms.
• The app carries out calls to load Dex modules, where additional code is packed from files with a.so extension at runtime.
• The.so files themselves reverse and make extra calls to dlopen(), which can be used to pack additional.so files. This facility is not normally examined by Google Play Protect and other static analysis services.
• The.so files can be implemented in native code, such as C++. Using native code includes a layer of complexity to the analysis procedure and obscures the complete level of the app’s capabilities. Moreover, native code can be leveraged to more quickly intensify advantages, potentially making use of vulnerabilities within the os or gadget hardware.
  
  Remarks
  
  While data collection prevails in contemporary applications for debugging and enhancing user experience, aggressive fingerprinting raises significant privacy concerns. The DeepSeek app needs users to visit with a legitimate email, which ought to currently provide sufficient authentication. There is no valid reason for the app to strongly gather and transfer unique gadget identifiers, IMEI numbers, SIM card details, and other non-resettable system properties.
  
  The level of tracking observed here surpasses normal analytics practices, possibly making it possible for consistent user tracking and re-identification across gadgets. These behaviors, combined with obfuscation strategies and network interaction with third-party tracking services, prawattasao.awardspace.info warrant a higher level of analysis from security researchers and users alike.
  
  The employment of runtime code filling along with the bundling of native code suggests that the app might permit the release and execution of unreviewed, from another location delivered code. This is a serious possible attack vector. No proof in this report exists that from another location deployed code execution is being done, just that the facility for this appears present.
  
  Additionally, the app’s approach to spotting rooted gadgets appears excessive for an AI chatbot. Root detection is frequently justified in DRM-protected streaming services, where security and content security are crucial, or in competitive computer game to avoid unfaithful. However, there is no clear rationale for such rigorous steps in an application of this nature, raising further concerns about its intent.
  
  Users and companies considering installing DeepSeek must understand these possible risks. If this application is being used within an enterprise or federal government environment, extra vetting and security controls ought to be implemented before allowing its release on handled devices.
