Obiceiul de a l\u0103sa cheile pe mas\u0103, l\u00e2ng\u0103 u\u0219a de la intrare, pare banal. \u00cens\u0103, odat\u0103 cu evolu\u021bia ma\u0219inilor, acest gest poate deveni un risc. P\u00e2n\u0103 \u00een 2023, peste un milion de autoturisme au fost furate \u00een Statele Unite, iar anchetatorii spun c\u0103 ho\u021bii nu mai folosesc doar for\u021ba brut\u0103. Ei combin\u0103 metodele clasice cu tehnologia modern\u0103 pentru a fura ma\u0219ini f\u0103r\u0103 s\u0103 lase urme, scrie Economic Times.<\/a><\/p>\n

Potrivit National Insurance Crime Bureau, infractorii folosesc din ce \u00een ce mai des metode sofisticate care exploateaz\u0103 sistemele \u201ekeyless\u201d. Ceea ce era considerat c\u00e2ndva un avantaj a devenit, \u00een unele cazuri, o vulnerabilitate.<\/p>\n

Sistemele de acces f\u0103r\u0103 cheie func\u021bioneaz\u0103 prin semnale wireless transmise constant \u00eentre ma\u0219in\u0103 \u0219i telecomand\u0103. C\u00e2nd vehiculul detecteaz\u0103 cheia \u00een apropiere, u\u0219ile se deblocheaz\u0103 automat. Inginerii de la Analog Devices arat\u0103 c\u0103 peste 70% dintre ma\u0219inile moderne folosesc astfel de tehnologii, bazate pe frecven\u021be radio.<\/p>\n

Pentru \u0219oferi, totul pare simplu \u0219i comod. \u00cen realitate, aceste semnale pot fi interceptate, amplificate sau redirec\u021bionate.<\/p>\n

Cea mai frecvent\u0103 metod\u0103 folosit\u0103 de ho\u021bii moderni se nume\u0219te \u201erelay attack\u201d. Nu presupune spargerea geamurilor sau for\u021barea \u00eencuietorilor, ci captarea \u0219i retransmiterea semnalului.<\/p>\n

De obicei, ac\u021bioneaz\u0103 dou\u0103 persoane: una st\u0103 l\u00e2ng\u0103 ma\u0219in\u0103, cealalt\u0103 \u00een apropierea cheii (de exemplu, \u00een interiorul locuin\u021bei). Cu ajutorul unor dispozitive, semnalul cheii este captat \u0219i transmis c\u0103tre ma\u0219in\u0103, care \u201ecrede\u201d c\u0103 cheia este l\u00e2ng\u0103 ea \u0219i se deblocheaz\u0103 instant.<\/p>\n

Studiile arat\u0103 c\u0103 semnalul poate ajunge p\u00e2n\u0103 la aproximativ 15 metri \u00een interiorul unei case, ceea ce \u00eenseamn\u0103 c\u0103 o cheie l\u0103sat\u0103 l\u00e2ng\u0103 u\u0219\u0103 sau fereastr\u0103 poate fi detectat\u0103 din exterior. Cercet\u0103tori precum Aurelien Francillon, Boris Danev \u0219i Srdjan Capkun au demonstrat c\u0103 astfel de atacuri pot func\u021biona chiar \u0219i atunci c\u00e2nd cheia<\/a> se afl\u0103 la zeci de metri distan\u021b\u0103.<\/p>\n

\t\t\tFolia de aluminiu, o solu\u021bie simpl\u0103<\/p>\n

Pentru a reduce acest risc, unii \u0219oferi au apelat la o metod\u0103 nea\u0219teptat\u0103: \u00eenvelirea cheii \u00een folie de aluminiu. De\u0219i pare ciudat, principiul este valid.<\/p>\n

Folia ac\u021bioneaz\u0103 ca o versiune simpl\u0103 a unei \u201ecu\u0219ti Faraday\u201d, concept asociat fizicianului\u00a0Michael Faraday. Aceasta blocheaz\u0103 semnalele electromagnetice<\/a>, \u00eempiedic\u00e2ndu-le s\u0103 ias\u0103 sau s\u0103 intre.<\/p>\n

Potrivit\u00a0National High Magnetic Field Laboratory, astfel de \u201e\u00eenveli\u0219uri\u201d pot opri undele radio, izol\u00e2nd dispozitivul din interior. Chiar dac\u0103 folia nu este perfect\u0103, ea poate reduce semnificativ semnalul dac\u0103 este folosit\u0103 corect.<\/p>\n

Cum func\u021bioneaz\u0103 \u00een practic\u0103<\/p>\n

Eficien\u021ba depinde de c\u00e2t de bine este acoperit\u0103 cheia. Orice spa\u021biu liber poate permite semnalului s\u0103 \u201escape\u201d. Mai multe straturi de folie \u0219i marginile bine sigilate cresc protec\u021bia.<\/p>\n

Este recomandat \u0219i un test simplu: pui cheia \u00een folie \u0219i te apropii de ma\u0219in\u0103. Dac\u0103 aceasta nu se mai deblocheaz\u0103, \u00eenseamn\u0103 c\u0103 metoda func\u021bioneaz\u0103. Aceast\u0103 recomandare este f\u0103cut\u0103 inclusiv de poli\u021bie.<\/p>\n

De asemenea, conteaz\u0103 unde sunt p\u0103strate cheile. Dac\u0103 sunt \u021binute departe de u\u0219i \u0219i ferestre, riscul scade, mai ales dac\u0103 protec\u021bia nu este perfect\u0103.<\/p>\n

\t\t\tNu este o solu\u021bie complet\u0103<\/p>\n

Folia de aluminiu poate ajuta, dar nu elimin\u0103 complet riscul. Ma\u0219inile pot fi furate \u0219i prin alte metode, precum tractarea sau for\u021barea accesului.<\/p>\n

Exper\u021bii recomand\u0103 m\u0103suri suplimentare: huse speciale care blocheaz\u0103 semnalul, dezactivarea cheii c\u00e2nd nu este folosit\u0103 \u0219i actualizarea sistemelor de securitate.<\/p>\n

Organiza\u021bii precum Thatcham Research subliniaz\u0103 importan\u021ba unei protec\u021bii \u00een mai multe straturi.<\/p>\n

Produc\u0103torii auto \u00eencearc\u0103 deja s\u0103 \u00eembun\u0103t\u0103\u021beasc\u0103 securitatea. Tehnologii precum Ultra Wideband pot m\u0103sura mai precis distan\u021ba dintre cheie \u0219i ma\u0219in\u0103, reduc\u00e2nd riscul atacurilor. Unele chei moderne au senzori de mi\u0219care \u0219i nu mai emit semnal dac\u0103 stau nemi\u0219cate.<\/p>\n
