I conducted a static analysis of DeepSeek, a Chinese LLM chatbot, using variation 1.8.0 from the Google Play Store. The objective was to recognize possible security and privacy issues.

I have actually composed about DeepSeek formerly here.

Additional security and personal privacy issues about DeepSeek have been raised.

See likewise this analysis by NowSecure of the iPhone version of DeepSeek

The findings detailed in this report are based simply on static analysis. This suggests that while the code exists within the app, there is no definitive proof that all of it is performed in practice. Nonetheless, the existence of such code warrants scrutiny, especially given the growing issues around data privacy, security, surgiteams.com the prospective abuse of AI-driven applications, and cyber-espionage characteristics between global powers.

Key Findings

Suspicious Data Handling & Exfiltration

- Hardcoded URLs direct information to external servers, raising issues about user activity tracking, such as to ByteDance "volce.com" endpoints. NowSecure recognizes these in the iPhone app the other day as well.

• Bespoke file encryption and data obfuscation approaches are present, with indications that they could be used to exfiltrate user details.
• The app contains hard-coded public keys, rather than counting on the user gadget's chain of trust.
• UI interaction tracking captures detailed user behavior without clear authorization. - WebView control is present, which might permit the app to gain access to personal external browser data when links are opened. More details about WebView controls is here
  
  Device Fingerprinting & Tracking
  
  A substantial part of the examined code appears to focus on gathering device-specific details, which can be utilized for tracking and fingerprinting.
  
  - The app gathers numerous special gadget identifiers, including UDID, Android ID, IMEI, IMSI, and provider details.
• System residential or commercial properties, installed packages, and root detection systems suggest potential anti-tampering measures. E.g. probes for the existence of Magisk, a tool that personal privacy supporters and security scientists utilize to root their Android devices.
• Geolocation and network profiling are present, suggesting potential tracking abilities and making it possible for or of fingerprinting routines by area.
• Hardcoded gadget model lists suggest the application may behave differently depending upon the detected hardware.
• Multiple vendor-specific services are utilized to extract extra device details. E.g. if it can not figure out the gadget through standard Android SIM lookup (because authorization was not granted), it attempts manufacturer specific extensions to access the very same details.
  
  Potential Malware-Like Behavior
  
  While no conclusive conclusions can be drawn without dynamic analysis, numerous observed habits align with recognized spyware and malware patterns:
  
  - The app uses reflection and UI overlays, which might assist in unauthorized screen capture or phishing attacks.
• SIM card details, identification numbers, and other device-specific data are aggregated for unidentified functions.
• The app implements country-based gain access to constraints and "risk-device" detection, recommending possible surveillance mechanisms.
• The app executes 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 fill additional.so files. This facility is not usually examined by Google Play Protect and other static analysis services.
• The.so files can be executed in native code, such as C++. Making use of native code adds a layer of complexity to the analysis process and obscures the full degree of the app's abilities. Moreover, native code can be leveraged to more easily intensify benefits, potentially making use of vulnerabilities within the os or device hardware.
  
  Remarks
  
  While information collection prevails in contemporary applications for debugging and improving user experience, aggressive fingerprinting raises significant privacy issues. The DeepSeek app needs users to visit with a valid email, which must already supply enough authentication. There is no legitimate factor for the app to aggressively collect and send unique gadget identifiers, trademarketclassifieds.com IMEI numbers, SIM card details, and other non-resettable system properties.
  
  The degree of tracking observed here surpasses normal analytics practices, possibly making it possible for consistent user tracking and re-identification throughout devices. These habits, combined with obfuscation techniques and network interaction with third-party tracking services, call for a greater level of scrutiny from security researchers and users alike.
  
  The work of runtime code filling in addition to the bundling of native code recommends that the app could allow the release and execution of unreviewed, remotely delivered code. This is a major possible attack vector. No proof in this report is presented that from another location released code execution is being done, just that the center for this appears present.
  
  Additionally, the app's method to identifying rooted gadgets appears excessive for an AI chatbot. Root detection is frequently justified in DRM-protected streaming services, where security and content protection are vital, or in competitive computer game to avoid unfaithful. However, there is no clear reasoning for such rigorous measures in an application of this nature, raising more questions about its intent.
  
  Users and organizations thinking about setting up DeepSeek ought to understand these potential risks. If this application is being utilized within an enterprise or federal government environment, additional vetting and demo.qkseo.in security controls should be implemented before permitting its deployment on handled gadgets.
  
  Disclaimer: The analysis provided in this report is based upon static code evaluation and does not indicate that all detected functions are actively used. Further investigation is needed for conclusive conclusions.
