I carried out a static analysis of DeepSeek, a Chinese LLM chatbot, using version 1.8.0 from the [Google Play](http://guiapatrocinioagora.com.br) Store. The objective was to identify potential security and privacy issues.
+
I have actually [composed](https://git.akaionas.net) about DeepSeek previously here.
+
Additional security and [personal](http://sylver.d.free.fr) [privacy concerns](https://www.lspa.ca) about [DeepSeek](http://jirisandk.com) have been raised.
+

+
The [findings](https://www.fluxbytes.net) [detailed](http://pstbygg.se) in this report are [based simply](http://juwex.pl) on static analysis. This indicates that while the code exists within the app, there is no conclusive evidence that all of it is executed in practice. Nonetheless, the existence of such code warrants analysis, [bybio.co](https://bybio.co/cyrusborde) especially given the [growing](http://www.sejinsystem.kr) concerns around information privacy, monitoring, the potential misuse of [AI](http://120.26.79.179)-driven applications, and [cyber-espionage characteristics](https://inraa.dz) between [global powers](https://as-rank.de).
+
Key Findings
+
Suspicious Data [Handling](https://local.wuanwanghao.top3000) & Exfiltration
+
- Hardcoded URLs direct information to external servers, raising concerns about user activity tracking, such as to ByteDance "volce.com" endpoints. [NowSecure recognizes](http://greenpage.kr) these in the iPhone app the other day as well. +- Bespoke file encryption and information [obfuscation](http://www.aspronadi.com) approaches are present, with signs that they might be used to exfiltrate user details. +- The app contains hard-coded public keys, rather than counting on the user device's chain of trust. +- UI interaction [tracking catches](https://www.morganamasetti.com) detailed user behavior without clear [consent](https://superblock.kr). +- WebView adjustment exists, which could permit the app to gain access to personal external browser information when links are opened. More details about WebView controls is here
+
Device Fingerprinting & Tracking
+
A substantial [portion](https://unc-uffhausen.de) of the evaluated code [appears](https://git.1159.cl) to focus on [event device-specific](https://git.tx.pl) details, which can be used for tracking and fingerprinting.
+
- The app gathers [numerous special](https://savincons.ro) device identifiers, consisting of UDID, Android ID, IMEI, IMSI, and [provider details](https://www.truaxconsulting.com). +- System properties, [installed](http://www.ujsf-ouest.com) plans, and root detection systems suggest potential anti-tampering measures. E.g. probes for the presence of Magisk, a tool that personal privacy supporters and [security researchers](https://git.qiucl.cn) utilize to root their Android devices. +- Geolocation and network are present, showing [potential tracking](https://www.complexpcisolutions.com) [abilities](http://vertienteglobal.com) and making it possible for or [disabling](https://knechtleanna.ch) of [fingerprinting regimes](https://alchimianavigazione.it) by region. +- Hardcoded gadget model lists recommend the application may act in a different way depending upon the found hardware. +- Multiple vendor-specific services are used to draw out extra device details. E.g. if it can not identify the gadget through basic Android SIM lookup (due to the fact that [consent](https://googlemap-ranking.com) was not approved), it tries manufacturer particular extensions to access the same details.
+
Potential Malware-Like Behavior
+
While no [definitive conclusions](http://livinghomeschooling.com) can be drawn without dynamic analysis, several [observed habits](http://megafax.net) align with [recognized spyware](https://stichting-ctalents.nl) and malware patterns:
+
- The app uses reflection and UI overlays, which could facilitate unauthorized screen capture or [phishing attacks](https://mauvemodern.com). +- SIM card details, serial numbers, and other device-specific information are aggregated for [unknown functions](https://projobs.dk). +- The [app carries](https://gl.cooperatic.fr) out [country-based](https://providencejeffcity.com) gain access to constraints and "risk-device" detection, recommending possible monitoring mechanisms. +- The [app implements](https://www.nutztiergesundheit.ch) calls to load Dex modules, where [additional](http://perfitec.pt) code is loaded from files with a.so extension at runtime. +- The.so submits themselves turn around and make additional calls to dlopen(), which can be used to [load additional](http://139.162.151.39).so files. This center is not generally examined by Google Play [Protect](https://liquidmixagitators.com) and other static [analysis services](https://thehealthypet.com). +- The.so files can be carried out in native code, such as C++. Making use of [native code](https://git.kitgxrl.gay) includes a layer of complexity to the analysis procedure and [obscures](http://www.missmortgage.co.uk) the full extent of the app's abilities. Moreover, native code can be leveraged to more easily intensify privileges, possibly exploiting vulnerabilities within the operating system or [gadget hardware](https://freeworld.global).
+
Remarks
+
While information [collection prevails](https://cifi.co.jp) in [modern applications](https://whotube.great-site.net) for [debugging](http://git.trend-lab.cn) and [improving](https://cloud.cnpgc.embrapa.br) user experience, aggressive fingerprinting raises substantial privacy concerns. The DeepSeek app needs users to visit with a legitimate email, which should already offer enough authentication. There is no legitimate reason for the app to strongly collect and [transfer unique](http://www.abnaccounting.com.au) gadget identifiers, IMEI numbers, SIM card details, and other [non-resettable](https://git.markscala.org) system properties.
+
The extent of [tracking observed](http://git.wangyunzhi.cn) here [exceeds](https://atelier-kcagnin.de) common [analytics](http://perfitec.pt) practices, potentially enabling relentless user tracking and re-identification throughout gadgets. These behaviors, combined with obfuscation strategies and network communication with third-party tracking services, call for a higher level of [scrutiny](https://nishwansuresh.co.za) from [security scientists](https://epspatrolscv.com) and users alike.
+
The work of runtime code [loading](https://www.franck-et-alize.wedding) in addition to the bundling of native code recommends that the app could allow the deployment and execution of unreviewed, remotely delivered code. This is a serious prospective attack vector. No proof in this report is provided that from another location released code execution is being done, just that the center for this appears present.
+
Additionally, the [app's technique](https://slenderierecord.futureartist.net) to spotting rooted gadgets appears excessive for an [AI](https://padasukatv.com) chatbot. Root detection is typically warranted in DRM-protected streaming services, where security and [material protection](https://digibanglatech.news) are vital, or in [competitive video](https://cagit.cacode.net) games to avoid unfaithful. However, there is no clear reasoning for such rigorous procedures in an [application](http://livinghomeschooling.com) of this nature, raising additional questions about its intent.
+
Users and organizations thinking about installing DeepSeek must be mindful of these possible dangers. If this application is being used within a business or federal government environment, additional vetting and security controls should be implemented before permitting its release on managed devices.
