K\u00ebrkuesit nga Instituti Koreano i Teknologjive t\u00eb Avancuara publikuan instrumentin LTESniffer, i cili lejon t\u00eb organizoni p\u00ebrgjesh\u00ebsin\u00eb dhe kapjen e trafikut midis stacionit baz\u00eb dhe telefonit celular n\u00eb rrjetet 4G LTE n\u00eb m\u00ebnyr\u00eb pasive (pa d\u00ebrguar sinjale n\u00eb aj\u00ebr). Ky instrument ofron utilitetet p\u00ebr organizimin e kapjes s\u00eb trafikut dhe realizimin e API p\u00ebr p\u00ebrdorimin e funksionalitetit LTESniffer n\u00eb aplikacione t\u00eb jashtme. <\/p>\n

LTESniffer siguron dekodimin e kanalit fizik PDCCH (Physical Downlink Control Channel) p\u00ebr t\u00eb marr\u00eb informacion mbi trafikun nga stacioni baz\u00eb (DCI, Downlink Control Information) dhe identifikator\u00ebt e p\u00ebrkohsh\u00ebm t\u00eb rrjetit (RNTI, Radio Network Temporary Identifier). P\u00ebrcaktimi i DCI dhe RNTI m\u00eb pas lejon dekodimin e t\u00eb dh\u00ebnave nga kanalet PDSCH (Physical Downlink Shared Channel) dhe PUSCH (Physical Uplink Shared Channel) p\u00ebr t\u00eb aksesuar trafikun e ardhsh\u00ebm dhe t\u00eb ardhsh\u00ebm. Megjithat\u00eb, LTESniffer nuk merret me dekriptimin e mesazheve t\u00eb enkriptuara q\u00eb d\u00ebrgohen midis telefonit celular dhe stacionit baz\u00eb, por ofron akses vet\u00ebm n\u00eb informacionin q\u00eb transmetohet n\u00eb m\u00ebnyr\u00eb t\u00eb hapur. P\u00ebr shembull, mesazhet q\u00eb d\u00ebrgohen nga stacioni baz\u00eb n\u00eb m\u00ebnyr\u00eb t\u00eb transmetuar masivisht dhe mesazhet fillestare t\u00eb lidhjes d\u00ebrgohen pa enkriptim, duke mund\u00ebsuar mbledhjen e informacionit p\u00ebr numrin nga i cili, kur dhe n\u00eb cilin num\u00ebr jan\u00eb realizuar thirrjet. <\/p>\n

P\u00ebr organizimin e kapjes \u00ebsht\u00eb e nevojshme nj\u00eb pajisje shtes\u00eb. P\u00ebr t\u00eb kapur trafikun vet\u00ebm nga stacioni baz\u00eb, mjafton nj\u00eb transmetues marr\u00ebs i programuesh\u00ebm (SDR) USRP B210 me dy antena, me nj\u00eb kostosh prej rreth $2000. P\u00ebr t\u00eb kapur trafikun nga telefoni celular n\u00eb stacionin baz\u00eb, nevojitet nj\u00eb kart\u00eb SDR m\u00eb e shtrenjt\u00eb USRP X310 me dy transmetues t\u00eb tjer\u00eb (kostoja e paket\u00ebs rreth $11000), pasi p\u00ebr p\u00ebrgjesh\u00ebsin\u00eb pasive t\u00eb paketave t\u00eb d\u00ebrguara nga telefonat k\u00ebrkohet sinkronizim i sakt\u00eb i koh\u00ebs midis kornizave t\u00eb d\u00ebrguara dhe t\u00eb pranuara dhe marrja e sinjaleve n\u00eb dy gamet e ndryshme t\u00eb frekuencave nj\u00ebkoh\u00ebsisht. P\u00ebr dekodimin e protokollit gjithashtu k\u00ebrkohet nj\u00eb kompjuter mjaft i fuqish\u00ebm, p\u00ebr shembull, p\u00ebr analizimin e trafikut t\u00eb stacionit baz\u00eb me 150 p\u00ebrdorues aktiv\u00eb, rekomandohet nj\u00eb sistem CPU Intel i7 me 16GB RAM. <\/p>\n
