Hulumtuesit nga Instituti Koreano i Teknologjive t\u00eb Avancuara publikuan mjetin LTESniffer, i cili lejon organizimin e p\u00ebrgjesh\u00ebm (pa d\u00ebrguar sinjale n\u00eb aj\u00ebr) p\u00ebr t\u00eb p\u00ebrgjuar dhe kapur trafikun midis stacionit baz\u00eb dhe telefonit celular n\u00eb rrjetet 4G LTE. Ky mjet ofron utilitar p\u00ebr organizimin e kapjes s\u00eb trafikut dhe realizimin e API-s\u00eb p\u00ebr p\u00ebrdorimin e funksionalitetit t\u00eb LTESniffer n\u00eb aplikacione t\u00eb pal\u00ebve t\u00eb treta. <\/p>\n

LTESniffer ofron dekodimin e kanalit fizik PDCCH (Physical Downlink Control Channel) p\u00ebr t\u00eb marr\u00eb informacion rreth trafikut nga stacioni baz\u00eb (DCI, Downlink Control Information) dhe identifikuesve t\u00eb p\u00ebrkohsh\u00ebm t\u00eb rrjetit (RNTI, Radio Network Temporary Identifier). Identifikimi i DCI dhe RNTI lejon m\u00eb pas dekodimin e t\u00eb dh\u00ebnave nga kanalet PDSCH (Physical Downlink Shared Channel) dhe PUSCH (Physical Uplink Shared Channel) p\u00ebr t\u00eb siguruar akses n\u00eb trafikun q\u00eb hyn dhe del. Sidoqoft\u00eb, LTESniffer nuk merret me dekriptimin e mesazheve t\u00eb kriptuara q\u00eb d\u00ebrgohen midis telefonit celular dhe stacionit baz\u00eb, por ofron qasje 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 mod\u00eb transmetimi t\u00eb p\u00ebrgjithsh\u00ebm dhe mesazhet fillestare t\u00eb lidhjes d\u00ebrgohen pa kriptim, duke lejuar mbledhjen e informacionit se nga cili num\u00ebr, kur dhe n\u00eb cilin num\u00ebr jan\u00eb b\u00ebr\u00eb thirrjet. <\/p>\n

P\u00ebr organizimin e kapjes nevojitet pajisje shtes\u00eb. P\u00ebr t\u00eb p\u00ebrgjuar trafikun vet\u00ebm nga stacioni baz\u00eb, mjafton nj\u00eb transmetues\/pranues i programuesh\u00ebm (SDR) USRP B210 me dy antena, me \u00e7mim rreth $2000. P\u00ebr t\u00eb p\u00ebrgjuar trafikun nga telefoni celular n\u00eb stacionin baz\u00eb k\u00ebrkohet nj\u00eb bord SDR m\u00eb t\u00eb shtrenjt\u00eb USRP X310 me dy transmetues\/pranues shtes\u00eb (kostoja e paket\u00ebs rreth $11000), pasi p\u00ebr p\u00ebrgjuar n\u00eb m\u00ebnyr\u00eb pasive paketat q\u00eb d\u00ebrgohen nga telefonat, k\u00ebrkohet sinkronizim i sakt\u00eb i koh\u00ebs midis kadrove q\u00eb d\u00ebrgohen dhe priten dhe marrja e sinjaleve n\u00eb dy frekuenca t\u00eb ndryshme n\u00eb t\u00eb nj\u00ebjt\u00ebn koh\u00eb. P\u00ebr dekodimin e protokollit gjithashtu k\u00ebrkohet nj\u00eb kompjuter mjaft i fuqish\u00ebm, p\u00ebr shembull, p\u00ebr analizimin e trafikut nga stacioni baz\u00eb me 150 p\u00ebrdorues aktiv \u00ebsht\u00eb e rekomanduar nj\u00eb sistem me CPU Intel i7 dhe 16GB RAM. <\/p>\n
