Na za\u010diatku bol kybernetick\u00fd \u00fatok na bezpe\u010dnostn\u00fdch \u0161pecialistov<\/h3>\n

Pozorovatelia Severnej K\u00f3rey si ned\u00e1vno mohli v\u0161imn\u00fa\u0165, \u017ee krajina rie\u0161i nejak\u00e9 v\u00e1\u017ene probl\u00e9my s pripojen\u00edm.

Najmenej jeden z centr\u00e1lnych smerova\u010dov, ktor\u00e9 umo\u017e\u0148uj\u00fa pr\u00edstup k sie\u0165am krajiny, sa v jednom momente zdal by\u0165 paralyzovan\u00fd, \u010do ochromilo digit\u00e1lne spojenie krajiny s vonkaj\u0161\u00edm svetom.<\/p>\n

Spo\u010diatku sa pozorovatelia domnievali, \u017ee ide o kybernetick\u00fd \u00fatok<\/strong> niektorej krajiny\u00a0 ako reakciu na s\u00e9riu testov rakiet.<\/p>\n

Zodpovednos\u0165 za pokra\u010duj\u00face v\u00fdpadky internetu v Severnej K\u00f3rei v\u0161ak nenesie americk\u00e9 kybernetick\u00e9 velenie ani \u017eiadna in\u00e1 \u0161t\u00e1tom podporovan\u00e1 hackersk\u00e1 agent\u00fara. V skuto\u010dnosti to bola pr\u00e1ca jedn\u00e9ho Ameri\u010dana v tri\u010dku, py\u017eamov\u00fdch nohaviciach a papu\u010diach, ktor\u00fd noc \u010do noc sedel vo svojej ob\u00fdva\u010dke, pozeral filmy o mimozem\u0161\u0165anoch a jedol pikantn\u00e9 kukuri\u010dn\u00e9 \u200b\u200bpochutiny \u2013 a pravidelne chodil do svojej pracovne kontrolova\u0165 priebeh programov, ktor\u00e9 sp\u00fa\u0161\u0165al, aby naru\u0161il internet v celej krajine<\/strong>.<\/p>\n

Najlep\u0161ia obrana je \u00fatok<\/h3>\n

Pred viac ako rokom bol nez\u00e1visl\u00fd hacker, ktor\u00fd sa predstavuje ako P4x, s\u00e1m hacknut\u00fd severok\u00f3rejsk\u00fdmi \u0161pi\u00f3nmi. P4x bol len jednou z obet\u00ed hackerskej kampane, ktor\u00e1 sa zamerala na z\u00e1padn\u00fdch bezpe\u010dnostn\u00fdch expertov so zjavn\u00fdm cie\u013eom ukradn\u00fa\u0165 ich hackersk\u00e9 n\u00e1stroje a podrobnosti o zranite\u013enostiach softv\u00e9ru. Hovor\u00ed, \u017ee sa mu podarilo zabr\u00e1ni\u0165, aby hackeri z\u00edskali \u010doko\u013evek cenn\u00e9. Napriek tomu sa c\u00edtil hlboko znepokojen\u00fd \u0161t\u00e1tom podporovan\u00fdmi hackermi, ktor\u00ed sa zamerali na neho osobne \u2013 a tie\u017e absenciou akejko\u013evek vidite\u013enej reakcie od vl\u00e1dy USA.<\/p>\n

Tak\u017ee po roku, ke\u010f nechal svoju nev\u00f4\u013eu dusi\u0165, P4x vzal veci do vlastn\u00fdch r\u00fak.<\/p>\n

P4x pre magaz\u00edn Wired potvrdil, \u017ee v severok\u00f3rejsk\u00fdch syst\u00e9moch na\u0161iel mno\u017estvo zn\u00e1mych bezpe\u010dnostn\u00fdch dier<\/strong>, ktor\u00e9 mu umo\u017enili samostatne spusti\u0165 \u00fatoky typu \u201eodmietnutie slu\u017eby\u201c (denial-of-service) na servery a smerova\u010de, od ktor\u00fdch z\u00e1vis\u00ed dostupnos\u0165 internetov\u00fdch slu\u017eieb v krajine. Hacker odmietol verejne odhali\u0165 tieto zranite\u013en\u00e9 miesta<\/strong>, preto\u017ee by pod\u013ea neho pomohli severok\u00f3rejskej vl\u00e1de br\u00e1ni\u0165 sa pred jeho \u00fatokmi. Ako pr\u00edklad v\u0161ak uviedol zn\u00e1mu chybu v softv\u00e9ri webov\u00e9ho servera NginX<\/strong>, ktor\u00e1 nespr\u00e1vne zaobch\u00e1dza s ur\u010dit\u00fdmi hlavi\u010dkami HTTP, \u010do umo\u017e\u0148uje servery, na ktor\u00fdch je softv\u00e9r spusten\u00fd, zahlti\u0165 a vypn\u00fa\u0165 ich. Nar\u00e1\u017eal tie\u017e na n\u00e1jdenie \u201estarobyl\u00fdch\u201c verzi\u00ed softv\u00e9ru webov\u00e9ho servera Apache a hovor\u00ed, \u017ee za\u010dal sk\u00fama\u0165 n\u00e1rodn\u00fd opera\u010dn\u00fd syst\u00e9m\u00a0 zn\u00e1my ako Red Star OS<\/strong>.<\/p>\n

P4x hovor\u00ed, \u017ee do zna\u010dnej miery zautomatizoval svoje \u00fatoky na severok\u00f3rejsk\u00e9 syst\u00e9my, pravidelne sp\u00fa\u0161\u0165al skripty, ktor\u00e9 vymen\u00favaj\u00fa, ktor\u00e9 syst\u00e9my zost\u00e1vaj\u00fa online, a potom sp\u00fa\u0161\u0165a exploity na ich odstr\u00e1nenie. Ak v\u00e1m tieto pojmy ve\u013ea nehovoria, nez\u00fafajte. S\u00e1m hacker v\u0161ak tvrd\u00ed, \u017ee pod\u013ea neho ide o mal\u00fd a\u017e stredne ve\u013ek\u00fd test penetr\u00e1cie, teda sk\u00fa\u0161ky bezpe\u010dnosti syst\u00e9mov.<\/p>\n

Be\u017en\u00fdch obyvate\u013eov sa kybernetick\u00fd \u00fatok na krajinu net\u00fdkal, preto\u017ee aj tak nemaj\u00fa pr\u00edstup na internet.

Hacker organizuje nov\u00fd, tentokr\u00e1t u\u017e skuto\u010dn\u00fd \u00fatok<\/h3>\n

Hacker uzn\u00e1va, \u017ee jeho \u00fatoky nie s\u00fa ni\u010d in\u00e9 ako \u201estrh\u00e1vanie vl\u00e1dnych transparentov alebo hyzdenie budov\u201c, ako hovor\u00ed. Ale tie\u017e tvrd\u00ed, \u017ee jeho hackovanie sa doteraz zameriavalo na testovanie a sk\u00famanie s cie\u013eom n\u00e1js\u0165 zranite\u013en\u00e9 miesta. Teraz m\u00e1 v \u00famysle pok\u00fasi\u0165 sa skuto\u010dne nab\u00fara\u0165 do severok\u00f3rejsk\u00fdch syst\u00e9mov, ukradn\u00fa\u0165 inform\u00e1cie a zdie\u013ea\u0165 ich s odborn\u00edkmi.<\/p>\n

Z\u00e1rove\u0148 d\u00fafa, \u017ee z\u00edska viac hacktivistov pre svoju vec pomocou webovej str\u00e1nky na dark webe, ktor\u00fa spustil v pondelok s n\u00e1zvom FUNK Project (FU North Korea) v n\u00e1deji, \u017ee vytvor\u00ed v\u00e4\u010d\u0161iu kolekt\u00edvnu palebn\u00fa silu.<\/p>\n

Dve strany mince<\/h3>\n

Pod\u013ea kritikov v\u0161ak nemus\u00ed by\u0165 hackersk\u00fd \u00faspech tak pozit\u00edvnym javom. To, \u017ee USA ani po roku od hackersk\u00fdch \u00fatokov nevykonali \u017eiadne medializovan\u00e9 kroky, neznamen\u00e1, \u017ee sa nedeje v\u00f4bec ni\u010d.<\/p>\n

Teoreticky je mo\u017en\u00e9, \u017ee teraz sa severok\u00f3rejsk\u00e1 vl\u00e1da s\u00fastred\u00ed na zv\u00fd\u0161enie bezpe\u010dnosti svojich siet\u00ed a skomplikuje tak u\u017e prebiehaj\u00face oper\u00e1cie zo strany USA.<\/p>\n

\u010eal\u0161ie kritiky \u010dinov hackera P4x s\u00fa o p\u00f4vode hackerov, ktor\u00ed ho napadli – s\u00edce boli objednan\u00ed Severnou K\u00f3reou, ale s najv\u00e4\u010d\u0161ou pravdepodobnos\u0165ou boli z \u010c\u00edny.<\/p>\n
