V\u00e1\u0161 flash disk byl, dokud jste na n\u011bj d\u00e1vali pozor a sv\u011bdomit\u011b se ho pokou\u0161eli neztratit, vcelku bezpe\u010dn\u00fd. Nikdo se do n\u011bj bez toho, abyste ho p\u0159ipojil k\u00a0po\u010d\u00edta\u010di, nedostal. Jako r\u00e1na z\u00a0\u010dist\u00e9ho nebe tedy p\u016fsob\u00ed novinka, \u017ee na internetov\u00e9m obchod\u011b Amazon je mo\u017en\u00e9 koupit jeho zlou verzi, tedy USBkill.USBkill, zl\u00e1 verze USB flash diskuUSBkill funguje na velmi jednoduch\u00e9m principu. Vypad\u00e1 p\u0159esn\u011b jako norm\u00e1ln\u00ed USB flash disk, nic ned\u00e1v\u00e1 najevo, \u017ee tento kus elektroniky naprosto zni\u010d\u00ed v\u00e1\u0161 po\u010d\u00edta\u010d nebo jin\u00e9 elektronick\u00e9 za\u0159\u00edzen\u00ed s\u00a0USB portem. Av\u0161ak jeho prim\u00e1rn\u00ed \u00falohou nen\u00ed \u00faschova dat. Po zastr\u010den\u00ed do va\u0161eho po\u010d\u00edta\u010de se USBkill rapidn\u00ed rychlost\u00ed nabije a v\u00a0r\u00e1mci milisekund vy\u0161le do USB portu elektrick\u00fd proud s\u00a0nap\u011bt\u00edm okolo 200 V. Ten b\u011bhem chvilky naprosto u\u0161kva\u0159\u00ed va\u0161i z\u00e1kladn\u00ed desku, kde se nach\u00e1z\u00ed v\u0161echna citliv\u00e1 elektronika. Pokud budete m\u00edt \u0161t\u011bst\u00ed, va\u0161e pevn\u00e9 ulo\u017ei\u0161t\u011b dat, tedy HDD a SDD disky z\u016fstanou netknuty a budete z\u00a0nich moci extrahovat va\u0161e data. V\u00a0opa\u010dn\u00e9m p\u0159\u00edpad\u011b se s\u00a0nimi nav\u017edy rozlu\u010dte, pr\u00e1v\u011b byly zni\u010deny ne\u00faprosn\u00fdm proudem. Tento proces se opakuje klidn\u011b i 100x za sekundu do doby, ne\u017e je USBkill odpojen.Nebezpe\u010dnost USBkill spo\u010d\u00edv\u00e1 pr\u00e1v\u011b v\u00a0tom, \u017ee na prvn\u00ed a i druh\u00fd pohled je nerozezn\u00e1te od norm\u00e1ln\u00edch USB flash disk\u016f. Teoreticky tedy m\u016f\u017eete naj\u00edt venku USB flash disk a omylem ho p\u0159ipojit k\u00a0va\u0161emu PC. Bohu\u017eel se ukazuje, \u017ee tato praktika je \u010d\u00edm d\u00e1l t\u00edm \u010dast\u011bj\u0161\u00ed, jak ukazuje relativn\u011b ned\u00e1vn\u00fd p\u0159\u00edpad, kter\u00fd se stal v\u00a0Spojen\u00fdch st\u00e1tech americk\u00fdch a p\u0159i n\u011bm\u017e byly zni\u010deny 2 po\u010d\u00edta\u010de. Je tedy velmi d\u016fle\u017eit\u00e9, abyste ke sv\u00e9mu po\u010d\u00edta\u010di nep\u0159ipojovali ciz\u00ed a nezn\u00e1m\u00e1 za\u0159\u00edzen\u00ed.                                                                                                                                                                                                                                                                                                                                                                                        4\/5 - (4 votes)        "},{"@context":"https:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Jsou USB flash disky po\u0159\u00e1d bezpe\u010dn\u00e9?","item":"https:\/\/www.celcz.cz\/jsou-usb-flash-disky-porad-bezpecne\/#breadcrumbitem"}]}]
