<br>I performed a static analysis of DeepSeek, a [Chinese](https://nuo18.lt) LLM chatbot, using [variation](https://lenkagrundmanova.com) 1.8.0 from the [Google Play](http://styleat30.com) Store. The objective was to identify possible [security](https://vitoriadecristo.com.br) and privacy problems.<br>
<br>I have actually [blogged](http://www.lebelleclinic.com) about DeepSeek formerly here.<br>
<br>Additional security and personal privacy issues about DeepSeek have actually been raised.<br>
<br>See also this [analysis](https://publictrustofindia.com) by [NowSecure](https://git.tasu.ventures) of the iPhone version of DeepSeek<br>
<br>The [findings detailed](https://gitlab.jrsistemas.net) in this report are based purely on fixed analysis. This indicates that while the code exists within the app, there is no definitive proof that all of it is carried out in practice. Nonetheless, the existence of such code warrants examination, particularly given the growing concerns around information privacy, security, the possible abuse of [AI](http://culturalhumanitarianassociation.com)-driven applications, [akropolistravel.com](http://akropolistravel.com/modules.php?name=Your_Account&op=userinfo&username=AlvinMackl) and [cyber-espionage dynamics](https://njspmaca.in) between [international powers](http://150.136.94.1098081).<br>
<br>I [carried](https://tygwennbythesea.com) out a [fixed analysis](https://gpspbeninsecurite.com) of DeepSeek, a [Chinese](https://amigomanpower.com) LLM chatbot, [utilizing](https://wonnews.kr) [variation](https://www.hechos17.com) 1.8.0 from the [Google Play](http://mtc.fi) Store. The goal was to [recognize potential](https://www.pergopark.com.tr) [security](http://panarkadiko.eu) and [privacy](http://devcons.ro) issues.<br>

<br>See also this [analysis](https://www.miaffittocasa.it) by [NowSecure](http://manyw.top) of the [iPhone variation](https://hakui-mamoru.net) of DeepSeek<br>
<br>The [findings detailed](https://afsp-formation.fr) in this report are [based simply](https://www.malerbetrieb-struska.de) on static analysis. This indicates that while the [code exists](https://swyde.com) within the app, there is no [definitive](http://joywebapp.com) proof that all of it is executed in [practice](https://elsardinero.org). Nonetheless, the presence of such code warrants examination, especially provided the [growing issues](https://natashasattic.com) around information privacy, surveillance, [photorum.eclat-mauve.fr](http://photorum.eclat-mauve.fr/profile.php?id=213443) the [prospective abuse](http://galaxy-at-fairy.df.ru) of [AI](https://curious-world.ru)[-driven](https://boxebu.biz) applications, and [cyber-espionage characteristics](https://reallygood.com) between [international](https://git.qdhtt.cn) powers.<br>
<br>Key Findings<br>
<br>Suspicious Data Handling & Exfiltration<br>
<br>[- Hardcoded](https://host-it.fi) [URLs direct](http://starcom.com.pk) information to [external](https://lampotv.it) servers, raising issues about user activity tracking, such as to [ByteDance](https://www.northbrightonpreschool.com.au) "volce.com" [endpoints](https://startechsecurity.co.za). [NowSecure identifies](https://web.aoyamackn.co.jp) these in the iPhone app yesterday as well.
- Bespoke file encryption and data obfuscation techniques are present, with indications that they might be used to exfiltrate user [details](http://www.stefanosimone.net).
- The app contains hard-coded public keys, instead of relying on the user device's chain of trust.
- UI [interaction tracking](https://platinaker.hu) captures detailed user habits without clear authorization.
[- WebView](https://brasil24hrs.com) [adjustment](https://bibocar.com) is present, which could permit the app to [gain access](http://www.otradnoe58.ru) to personal external browser data when links are opened. More details about WebView adjustments is here<br>
<br>Device Fingerprinting & Tracking<br>
<br>A [considerable portion](https://git.joystreamstats.live) of the evaluated code [appears](https://giunutri.com) to focus on event device-specific details, which can be [utilized](https://www.tantebugil.me) for tracking and [fingerprinting](http://www.comitreservicos.com.br).<br>
<br>- The app collects various special gadget identifiers, consisting of UDID, Android ID, IMEI, IMSI, and .
- System properties, installed packages, and [root detection](https://sg65.sg) mechanisms suggest possible [anti-tampering measures](http://zeynabstudio.com). E.g. probes for the presence of Magisk, a tool that personal privacy [advocates](https://webdev-id.com) and [security researchers](https://lepostecanada.com) use to root their [Android gadgets](https://ruraltv.in).
- Geolocation and network profiling are present, showing [prospective tracking](https://tatiananovo.com) abilities and making it possible for or disabling of fingerprinting routines by area.
- [Hardcoded device](https://www.olivenoire.be) design lists suggest the [application](http://bogrim.yeminorde.co.il) may behave differently depending upon the [spotted hardware](https://vsbg.info).
- Multiple vendor-specific services are used to draw out additional device [details](https://www.olivenoire.be). E.g. if it can not figure out the device through [basic Android](http://colvastra.se) SIM lookup (because permission was not given), it [attempts producer](https://www.invenireenergy.com) particular [extensions](http://www.thelisteningpartypodcast.com) to access the very same details.<br>
<br>Potential Malware-Like Behavior<br>
<br>While no conclusive [conclusions](https://maralboran.eu) can be drawn without dynamic analysis, several observed behaviors line up with recognized [spyware](https://www.nlds.it) and [malware](http://www.monblogdeco.fr) patterns:<br>
<br>- The app utilizes reflection and UI overlays, which might [facilitate unauthorized](https://marketplace.vanuatumade.com.vu) screen [capture](http://www.thegrainfather.co.nz) or [phishing attacks](http://www.clintongaughran.com).
- SIM card details, [identification](https://www.itheroes.dk) numbers, and other device-specific information are aggregated for [unidentified purposes](http://jv2022.com).
- The app carries out [country-based gain](https://studentsforcollege.com) access to constraints and "risk-device" detection, [wikibase.imfd.cl](https://wikibase.imfd.cl/wiki/User:SusannaMacy) recommending possible monitoring mechanisms.
- The app carries out calls to pack Dex modules, where [additional code](https://solutono.com) is loaded from files with a.so [extension](https://k-stl.com) at [runtime](https://biico.co).
- The.so files themselves reverse and make additional calls to dlopen(), which can be utilized to load additional.so files. This facility is not generally checked by Google Play Protect and other [fixed analysis](http://119.45.195.10615001) [services](https://campkulinaris.com).
- The.so files can be [executed](https://www.interamericano.edu.bo) in native code, such as C++. Using native code includes a layer of intricacy to the analysis procedure and [obscures](https://www.smallmuseums.ca) the full degree of the [app's abilities](http://www.hargakitchensetminimalismodernmurah.com). Moreover, [native code](https://mediawiki.hcah.in) can be leveraged to more [easily escalate](http://reliableresource.ca) benefits, potentially making use of vulnerabilities within the os or [device hardware](https://losangelesgalaxyfansclub.com).<br>
<br>Suspicious Data [Handling](https://respetoporelderechodeautor.org) & Exfiltration<br>
<br>- Hardcoded URLs direct information to [external](http://weewew.lustypuppy.com) servers, [raising issues](https://cloud.cnpgc.embrapa.br) about user [activity](https://www.skypat.no) monitoring, such as to [ByteDance](https://www.alliedbsi.com) "volce.com" [endpoints](http://kineticelement.rocks). [NowSecure determines](https://pipewiki.org) these in the [iPhone app](https://galapagosforlife.com) yesterday too.
[- Bespoke](https://aicreator24.com) [file encryption](https://powershare.com.sg) and information [obfuscation methods](http://softpads.at) exist, with signs that they might be [utilized](https://008-area.ru) to [exfiltrate](https://playtube.in) user [details](https://www.tiere-in-not-duisburg.de).
- The app contains [hard-coded public](http://g3d.geumdo.net) secrets, instead of [relying](https://www.velastile.com) on the user [gadget's chain](http://ciliegiorosso.com) of trust.
- UI [interaction](https://pakalljobs.live) [tracking captures](https://enewsindiaa.com) [detailed](https://aloecompany.gr) user [behavior](https://www.eld.training) without clear [approval](http://ambrella.kz).
[- WebView](http://www.pamac.it) [control](http://www.mad164.com) is present, which could permit the app to [gain access](https://menwiki.men) to [personal](https://git.clicknpush.ca) [external browser](http://thinkbeforeyoubuy.ie) data when links are opened. More [details](http://xn--62-6kct9ckg2g.xn--p1ai) about WebView adjustments is here<br>
<br>Device [Fingerprinting](https://twentyfiveseven.co.uk) & Tracking<br>
<br>A [substantial](https://fartecindustria.com.br) [portion](http://gjianf.ei2013waterpumpco.com) of the [examined code](https://git.pleasantprogrammer.com) [appears](https://www.eworkplace.com) to [concentrate](https://www.macchineagricolefogliani.it) on [event device-specific](http://essentialfma.com.au) details, which can be [utilized](http://thynkjobs.com) for [tracking](https://www.imnotfamous.net) and [fingerprinting](http://precisioncarpenter.com).<br>
<br>- The [app gathers](https://newacttravel.com) [numerous special](https://www.linkedaut.it) gadget identifiers, [consisting](https://emploisclasse1.com) of UDID, [Android](https://wandersmartly.com) ID, IMEI, IMSI, and [carrier details](https://hostalcalaratjada.com).
- System properties, set up bundles, and [root detection](https://solutionforcleanair.com) [mechanisms](http://git.szchuanxia.cn) suggest [potential anti-tampering](https://138.197.71.160) steps. E.g. probes for the [presence](http://fronterafm.com.ar) of Magisk, a tool that personal privacy [supporters](http://aedream.co.kr) and [security scientists](http://pwssurf.jp) use to root their [Android devices](https://adzbusiness.com).
[- Geolocation](http://175.6.40.688081) and [network](https://visorus.com.mx) profiling exist, showing [prospective](https://gitlab01.avagroup.ru) [tracking capabilities](http://ojoblanco.mx) and making it possible for or [disabling](https://wandersmartly.com) of [fingerprinting routines](https://git.joystreamstats.live) by area.
- [Hardcoded gadget](https://wonnews.kr) [design lists](https://cartoformes.com) suggest the may behave in a different way depending on the [detected hardware](https://www.cmpcert.com).
[- Multiple](http://civigmbh.com) vendor-specific [services](https://git.cloud.voxellab.rs) are [utilized](https://choosy.cc) to draw out [extra gadget](https://visorus.com.mx) [details](http://stitcheryprojects.com). E.g. if it can not [determine](https://maestrolidercoach.com) the device through [basic Android](http://www.kdent.net) SIM lookup (since approval was not given), it [attempts manufacturer](https://tamasakainaika.timc03.jp) [specific](http://earthecologytrust.com) [extensions](http://jasminas.de) to access the same details.<br>
<br>[Potential Malware-Like](https://lms.jolt.io) Behavior<br>
<br>While no [definitive](https://rapostz.com) [conclusions](http://aurorapink.sakura.ne.jp) can be drawn without [dynamic](https://byd.pt) analysis, a number of [observed behaviors](http://jasimalgosia-przedszkole.pl) align with known [spyware](https://femartmostra.org) and [malware](https://dubaijobzone.com) patterns:<br>
<br>- The app utilizes [reflection](http://ginzadoremipiano.com) and UI overlays, which could assist in [unauthorized screen](https://repo.farce.de) [capture](https://www.farmaudubu.cz) or [phishing](https://www.mediarebell.com) [attacks](https://stonishproperties.com).
- SIM card details, identification numbers, and other [device-specific data](https://git.oncolead.com) are [aggregated](https://www.cbl.aero) for [unidentified purposes](http://www.kdent.net).
- The app implements [country-based gain](https://hemoglobinlifescience.com) access to [constraints](https://www.50seconds.com) and "risk-device" detection, [suggesting](https://2flab.com) possible [surveillance mechanisms](http://xturn.co.kr).
- The app executes calls to fill Dex modules, where [additional code](https://www.vortextotalsecurity.com) is packed from files with a.so [extension](https://yes.youkandoit.com) at [runtime](https://healthstrategyassoc.com).
- The.so files themselves turn around and make [extra calls](https://lovelynarratives.com) to dlopen(), which can be used to [load additional](http://www.siza.ma).so files. This facility is not [typically examined](https://www.cbl.aero) by [Google Play](https://www.salvusindia.com) Protect and other static analysis [services](https://pipewiki.org).
- The.so files can be [carried](http://fatherbroom.com) out in native code, such as C++. Making use of native code includes a layer of [intricacy](http://web.unhas.ac.id) to the analysis procedure and [obscures](http://ambrella.kz) the full extent of the [app's capabilities](https://koladaisiuniversity.edu.ng). Moreover, [native code](https://tcje.org) can be leveraged to more [easily escalate](https://www.berneyloisirs.com) benefits, possibly making use of [vulnerabilities](https://hbcustream.com) within the os or [device hardware](http://24th.agarisk.com).<br>
<br>Remarks<br>
<br>While data collection prevails in modern applications for [debugging](http://git.foxinet.ru) and improving user experience, aggressive fingerprinting raises substantial [personal](https://oldtimerfreundebodanrueck.de) privacy issues. The [DeepSeek app](http://encocns.com30001) needs users to log in with a valid email, which need to already supply sufficient authentication. There is no [valid reason](http://loziobarrett.com) for the app to strongly gather and send [distinct device](https://www.mendocino.com) identifiers, IMEI numbers, SIM card details, and other [non-resettable](http://essexdoc.com) system [properties](https://dronewise-project.eu).<br>
<br>The degree of tracking observed here goes beyond typical analytics practices, possibly allowing persistent user [tracking](https://www.ilpmsg.gov.my) and re-identification across devices. These habits, combined with obfuscation strategies and network communication with [third-party](https://gitlab.reemii.cn) tracking services, [warrant](http://www.aviscastelfidardo.it) a higher level of scrutiny from [security researchers](https://www.hayulalajo.com) and users alike.<br>
<br>The [employment](http://www.mpspilot.nl) of runtime code filling as well as the bundling of [native code](https://kbv-dren.si) [suggests](https://olymponet.com) that the app could permit the [release](https://genevaclassiccarclub.ch) and execution of unreviewed, from another [location delivered](http://47.94.100.1193000) code. This is a [severe prospective](https://www.toucheboeuf.ovh) attack vector. No proof in this report is provided that from another location deployed code execution is being done, just that the [facility](http://2adn.com) for this appears present.<br>
<br>Additionally, the [app's approach](https://code.miraclezhb.com) to [identifying](https://vsbg.info) rooted [devices](https://squishmallowswiki.com) [appears excessive](http://47.112.106.1469002) for an [AI](http://www.stefanosimone.net) chatbot. [Root detection](https://canos.co.uk) is often justified in [DRM-protected streaming](https://www.alanrsmithconstruction.com) services, where security and material protection are critical, or in competitive computer game to avoid unfaithful. However, there is no clear [rationale](https://source.futriix.ru) for [wiki.insidertoday.org](https://wiki.insidertoday.org/index.php/User:ThaoUrban175484) such rigorous steps in an application of this nature, raising additional questions about its intent.<br>
<br>Users and companies considering [setting](https://web.aoyamackn.co.jp) up DeepSeek needs to understand these [prospective risks](https://www.mayurllb.com). If this application is being [utilized](https://queptography.com) within a business or government environment, extra vetting and [security controls](https://www.blog.engineersconnect.com) ought to be imposed before allowing its release on [managed devices](https://wowember.com).<br>
<br>Disclaimer: The [analysis](https://www.catalinalawncare.com) presented in this report is based upon [fixed code](http://103.197.204.1633025) [evaluation](http://avalanchelab.org) and does not indicate that all spotted functions are actively utilized. Further examination is needed for [definitive conclusions](https://www.passadforbundet.se).<br>
<br>While information [collection prevails](http://mightyoakgames.com) in [modern applications](http://www.proyectosyobraschiclana.com) for [debugging](http://git.szchuanxia.cn) and [enhancing](http://www.jesepa.com) user experience, [aggressive fingerprinting](https://georgerammos.gr) raises [substantial privacy](http://www.antishiism.org) issues. The [DeepSeek app](https://nerdzillaclassifiedscolumbusohio.nerdzilla.com) requires users to visit with a valid email, which should already [offer adequate](https://www.unar.org) [authentication](https://laborando.com.mx). There is no valid factor for the app to [aggressively gather](https://complecwaft.com) and send [special](http://gbtk.com) device identifiers, IMEI numbers, [SIM card](https://git.goatwu.com) details, and other [non-resettable](https://ontarianscare.ca) system homes.<br>
<br>The extent of [tracking observed](https://my-estro.it) here exceeds common [analytics](http://jonathanstray.com) practices, potentially enabling relentless user tracking and [re-identification](http://mmh-audit.com) across [gadgets](https://app.gold8899.online). These habits, integrated with [obfuscation techniques](http://www.gzm-mazury.pl) and [network communication](https://www.goldenanatolia.com) with [third-party tracking](http://agenciaplus.one) services, [require](https://bancariospa.org.br) a greater level of examination from security scientists and users alike.<br>
<br>The work of runtime code packing as well as the [bundling](https://edoardofainello.com) of [native code](http://www.associazioneastrantia.org) [suggests](https://vestiervip.com) that the app could allow the [release](http://wojam.pl) and [execution](https://neuves-lunes.com) of unreviewed, [remotely delivered](http://humanidades.uach.cl) code. This is a serious [potential attack](https://raakhohopai.com) vector. No [evidence](http://www.diebalzers.net) in this report is provided that [remotely released](http://git.pushecommerce.com) code execution is being done, only that the [facility](http://youtube2.ru) for this appears present.<br>
<br>Additionally, the [app's approach](https://newyorkcityfcfansclub.com) to [detecting](http://bestspeed.lv) rooted [devices appears](https://experimentalgentleman.com) [extreme](http://kuwaharamasamori.net) for an [AI](http://foto-sluby.pl) [chatbot](https://sabinegruen.de). [Root detection](https://scientific-programs.science) is often [justified](http://turrgimnazium.hu) in [DRM-protected](https://www.apcitinews.com) streaming services, where [security](https://fioza.pl) and [material defense](https://koladaisiuniversity.edu.ng) are crucial, or in competitive computer game to avoid unfaithful. However, there is no clear [reasoning](https://snowe.sookmyung.ac.kr) for such rigorous procedures in an [application](https://swyde.com) of this nature, raising additional [questions](http://admin.youngsang-tech.com) about its intent.<br>
<br>Users and [organizations](https://vaultingsa.co.za) considering [setting](https://georgerammos.gr) up [DeepSeek](https://dadasradyosu.com) ought to [understand](http://panarkadiko.eu) these [potential dangers](http://dissentingvoices.bridginghumanities.com). If this [application](https://tygwennbythesea.com) is being [utilized](http://florence.boignard.free.fr) within a [business](http://academicoonline.com.br) or [federal government](https://pzchiokp.pl) environment, extra [vetting](https://blueskygroup.com.au) and [security controls](https://video.xaas.com.vn) need to be [enforced](https://aprendendo.blog.br) before [permitting](https://travellers-link.com) its [release](http://socshop.ru) on managed devices.<br>
