Derudover giver det brugere, der bruger et enkelt netv\u00e6rk, mulighed for at bruge et andet, f.eks. n\u00e5r de rejser i et fremmed land.<\/p>\n<h2>Hvad kan hackere egentlig g\u00f8re med SS7?<\/h2>\n<p>N\u00e5r de f\u00e5r adgang til denne SS7-teknik, kan en hacker f\u00e5 adgang til pr\u00e6cis lige s\u00e5 mange oplysninger og aflytningskapaciteter som sikkerhedsudbyderne.<\/p>\n<p>De kan gennemskue opkald i forvejen og give dem mulighed for at lytte eller optage for dem. De kan gennemse SMS-beskeder, der leveres mellem telefoner, ogs\u00e5 overv\u00e5ge din telefons position ved hj\u00e6lp af n\u00f8jagtigt det system, som telefonnetv\u00e6rkene bruger til at holde en tjeneste tilbudt og ogs\u00e5 sende telefontekster, opkald sammen med information.<\/p>\n<h2>Hvordan f\u00e5r man adgang til brugen af et SS7-netv\u00e6rk?<\/h2>\n<p>St\u00f8rstedelen af de andre svar er ikke korrekte. SS7 har ingen taleopgaver. SS7 formidler alle oplysninger p\u00e5 en telefon over et netv\u00e6rk i pakkestil. Opkalds-ID, nogle kursusoplysninger, f.eks. identifikation af en krisehj\u00e6lper, alt sammen i mods\u00e6tning til det s\u00e6dvanlige opkald, alt p\u00e5 en telefon, bortset fra materialet, tilstand. SS7 udf\u00f8rer og opretter de links, der kr\u00e6ves for at finde sted p\u00e5 et netv\u00e6rk af den, der formidler din trafik, selv i dette scenarie.<\/p>\n<p>SS7 bruges i traditionelle telefonnetv\u00e6rk, s\u00e5 der er ikke noget krav om at udnytte det. Udstyret er dyrt og kan opn\u00e5s p\u00e5 visse punkter i netv\u00e6rket.<\/p>\n<p>At g\u00f8re det er en forbrydelse i henhold til Title 18, USC, og derfor vil FBI oprette dit bekendtskab, ud over beskyttelse af hjemlandet, fordi det er en national forbrydelse.<\/p>\n<h2>Pr\u00e6cis hvad er det muligt at g\u00f8re?<\/h2>\n<p>Det eneste middel til at beskytte sig mod SS7-angreb er altid at slukke for sin smartphone. Jeg og du ved, at det m\u00e5ske ikke er muligt. Det, du kan g\u00f8re, er at \"forst\u00e5 fjenden\". At v\u00e6re klar over, at opgaver som SS7-angreb er almindelige og bliver mere og mere udbredte, er nu vigtigt i 20 20.<\/p>\n<p>&nbsp;<\/p>\n<p>Men med alle de utallige mobiltelefonbrugere er muligheden for, at du bliver overv\u00e5get af cyberkriminelle, meget lille. Men hvis du tilf\u00e6ldigvis bliver l\u00e6ge, dronning og beskrevet som en pr\u00e6sident, der har smertefulde og f\u00f8lsomme individuelle oplysninger i sin egen mobil, er dine egne muligheder h\u00f8jere end for den normale person. Hvis du bruger 2FA til bankl\u00f8sninger, kan du v\u00e6re i fare for at f\u00e5 dine konti truet.<\/p>\n<p>&nbsp;<\/p>\n<p>I betragtning af n\u00f8jagtigt hvor enkelt det er at udf\u00f8re et SS7-angreb og ogs\u00e5 skade en du helt sikkert kan g\u00f8re for offeret s\u00e5vel som deres leverand\u00f8r, kan en person simpelthen forvente, at innovation inden for telekommunikation kan forsvare os slutbrugerne. For regeringsorganer, virksomheder og MSP'er er der nu en hel del muligheder, der sp\u00e6nder fra skr\u00e6ddersyede mobile VPN-tilgange til innovative muligheder som FirstPoint SIM-baseret sikkerhed p\u00e5 brugerniveau.<\/p>","protected":false},"excerpt":{"rendered":"<p>SS7 er designet til at udf\u00f8re out-band-signalering til hj\u00e6lp for denne produktion af c alle fakturerings-, routinginformationsmarkedsform\u00e5l i deres PSTN (offentlige koblede telefonnet).
