Til unders\u00f8gelsen blev de mest popul\u00e6re VPN-apps udvalgt, der distribueres via Google Play-kataloget. VPN-apps, hvor der blev identificeret sikkerheds- og privatlivsproblemer, er i alt blevet downloadet 2,4 milliarder gange. Hovedkonklusioner:    <\/p>\n<ul>\n<li class=\"l\"> I 61 apps (22%) blev der identificeret dataoverf\u00f8rsler uden brug af kryptering, der skete uden for den etablerede tunnel. De fleste apps i denne kategori er popul\u00e6re og har i gennemsnit 11 millioner downloads. I 18 apps blev der foretaget direkte anmodning til tjenesten ip-api.com for at bestemme placeringen af <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/lir\/ipv4\/\" title=\"IP-adressen\" data-wpil-keyword-link=\"linked\">IP-adressen<\/a> klienten.\n<p>I 5 tilf\u00e6lde blev konfigurationsfiler overf\u00f8rt til klienten uden kryptering, indeholdende parametre til forbindelse til VPN-serveren. Forskerne gennemf\u00f8rte et eksperiment og bekr\u00e6ftede muligheden for en MITM-angreb, der g\u00f8r det muligt at omdirigere trafikken til sin <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\" title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a>, hvilket giver mulighed for at tr\u00e6nge ind i offerets kommunikationskanal, fx n\u00e5r de er tilsluttet til et offentligt tr\u00e5dl\u00f8st netv\u00e6rk kontrolleret af angriberen. Problematisk apps (en komplet liste over alle apps, hvor der er identificeret problemer, findes p\u00e5 side 17 i PDF-rapporten):  <\/p>\n<ul>\n<li class=\"l\"> BambooVPN: Turbo Fast VPN (free.vpn.unblock.proxy.bamboovpn);\n<li class=\"l\"> VPN Pro (com.nebulatech.voocvpnpro);\n<li class=\"l\"> Free VPN (com.appoxide.freevpn);\n<li class=\"l\"> Hexa VPN (com.secure.vpn.proxy);\n<li class=\"l\"> 101 VPN (com.shwe.vpn101).  <\/ul>\n<p>Forskere har informeret om problemerne med forfatterne til disse applikationer, og efter et stykke tid blev der udf\u00f8rt en ny unders\u00f8gelse af de nyeste versioner, som viste, at s\u00e5rbarheden kun var blevet rettet i to applikationer \u2014 VPN Pro og Hexa VPN.    <\/p>\n<li class=\"l\"> Ved brug af 29 apps (10%) sker der en l\u00e6kage af trafik uden for den etablerede tunnel. I 24 apps, der har i alt 360 millioner downloads, skete der l\u00e6kage af informationer om bes\u00f8gte hjemmesider p\u00e5 grund af direkte DNS-anmodninger (20 sendte DNS-anmodninger via en lokal resolver, mens 6 gjorde det gennem offentlige DNS-tjenester som Google, Cloudflare, AliDNS og DNSPod). I 6 apps, der har 54 millioner downloads, blev der identificeret trafik sender uden for tunnelen relateret til brugerens aktivitet i webbrowseren. I 4 apps blev data sendt gennem en ukrypteret tunnel.    <img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/07\/6d7ae9a29d210a4b0d21ad47ad555b40.png\" style=\"display:block;margin: 0 auto\" \/>\n<li class=\"l\"> I 169 applikationer (60%) blev der ikke anvendt trafik-obfuskering, der blev anvendt standard netv\u00e6rksporte og protokoller, der kunne spores i det almindelige flow. Denne adf\u00e6rd stemmer ikke overens med brugernes forventninger \u2014 i overensstemmelse med en unders\u00f8gelse fra sidste \u00e5r mener 82% af VPN-brugere, at en VPN giver dem anonymitet.\n<li class=\"l\"> I 76 applikationer (27%) blev der sendt enhedernes unikke identifikatorer, AAID (Android Advertising ID), som g\u00f8r det muligt at spore enheder og brugere. I 246 applikationer (87%) blev der registreret trafik til kendte reklamenetv\u00e6rk og brugertracking-tjenester (i alt blev der registreret henvendelser til 3714 forskellige URL'er). En applikation sendte pr\u00e6cise GPS-koordinater for enheden.    <img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/07\/e9895cf2be1b5a0067ad4d932db977dc.png\" style=\"display:block;margin: 0 auto\" \/>\n<li class=\"l\"> I 107 applikationer (38%) blev der anvendt indstillinger, der ikke sikrer et optimalt sikkerhedsniveau. I 20 applikationer med samlet 40 millioner installationer blev der anvendt usikre krypteringsmetoder. I 96 applikationer med 728 millioner installationer blev der anvendt up\u00e5lidelige autentificeringsmekanismer.\n<p>I 3 applikationer var parameteren data-ciphers indstillet til 'none' i OpenVPN-indstillinger, hvilket tillader oprettelse af kommunikationskanaler uden kryptering. I 8 applikationer var parameteren 'cipher' indstillet til 'none', hvilket deaktiverer kryptering ved brug af OpenVPN 2.4 og tidligere versioner. I 12 applikationer blev der anvendt direktiver, der er blevet erkl\u00e6ret for\u00e6ldede. I 61 applikationer var direktiverne for blokering af kendte angrebsmetoder ikke inkluderet i OpenVPN-konfigurationen.            <\/ul>\n<p>Kilde: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65892\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0418\u0441\u0441\u043b\u0435\u0434\u043e\u0432\u0430\u0442\u0435\u043b\u0438 \u0438\u0437 \u041c\u0438\u0447\u0438\u0433\u0430\u043d\u0441\u043a\u043e\u0433\u043e \u0443\u043d\u0438\u0432\u0435\u0440\u0441\u0438\u0442\u0435\u0442\u0430 \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u0430\u043b\u0438 \u0438\u043d\u0441\u0442\u0440\u0443\u043c\u0435\u043d\u0442\u0430\u0440\u0438\u0439 MVPNalyzer \u0434\u043b\u044f \u0432\u044b\u044f\u0432\u043b\u0435\u043d\u0438\u044f \u0443\u0442\u0435\u0447\u0435\u043a \u0438\u043d\u0444\u043e\u0440\u043c\u0430\u0446\u0438\u0438 \u0438 \u0430\u043d\u0430\u043b\u0438\u0437\u0430 \u0440\u0430\u0431\u043e\u0442\u044b VPN, \u0438 \u043f\u0440\u043e\u0432\u0435\u0440\u0438\u043b\u0438 \u0441 \u0435\u0433\u043e \u043f\u043e\u043c\u043e\u0449\u044c\u044e 281 VPN-\u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0435 \u0434\u043b\u044f \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b Android. \u0414\u043b\u044f \u0438\u0437\u0443\u0447\u0435\u043d\u0438\u044f \u0431\u044b\u043b\u0438 \u043e\u0442\u043e\u0431\u0440\u0430\u043d\u044b \u043d\u0430\u0438\u0431\u043e\u043b\u0435\u0435 \u043f\u043e\u043f\u0443\u043b\u044f\u0440\u043d\u044b\u0435 VPN-\u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0439, \u0440\u0430\u0441\u043f\u0440\u043e\u0441\u0442\u0440\u0430\u043d\u044f\u0435\u043c\u044b\u0435 \u0447\u0435\u0440\u0435\u0437 \u043a\u0430\u0442\u0430\u043b\u043e\u0433 Google Play.
