    Ako napoved\u00e1 u\u017e n\u00e1zov, ide o v\u00fdskum \u0161kodliv\u00e9ho k\u00f3du. Misia ESETu je chr\u00e1ni\u0165 \u013eud\u00ed a na\u0161ou \u00falohou v r\u00e1mci tejto misie je porozumie\u0165 \u0161kodliv\u00e9mu k\u00f3du, \u010di\u017ee v\u00edrusom, tr\u00f3jskym ko\u0148om a tak \u010falej.

    Reverzn\u00e9 in\u017einierstvo je v princ\u00edpe opak programovania.

    M\u00e1m si to predstavi\u0165 tak, \u017ee v\u00fdskumn\u00edk pr\u00edde do pr\u00e1ce, otvor\u00ed po\u010d\u00edta\u010d a m\u00e1 na \u0148om dvesto riadkov k\u00f3du, pri\u010dom v nich h\u013ead\u00e1 nejak\u00e9 vzorce? Nie\u010do, ako v Matrixe?<\/em><\/strong><\/p>\n\n\n\n

    D\u00e1 sa to predstavi\u0165 aj takto. Anal\u00fdza prebieha dvoma z\u00e1kladn\u00fdmi formami: statickou a dynamickou. Statick\u00e1 znamen\u00e1, \u017ee sa pozer\u00e1m na k\u00f3d a iba ho \u010d\u00edtam, nespust\u00edm ho. Na za\u010diatku prebehne nie\u010do ako preklad. Program je v strojovom jazyku, teda nejak\u00e9 jednotky a nuly \u010di pr\u00edkazy, ktor\u00fdm rozumie procesor. To sa d\u00e1 prelo\u017ei\u0165 pomocou tzv. disassembleru do jazyka, ktor\u00fd je \u010ditate\u013en\u00fd analytikom. <\/p>\n\n\n\n

    D\u00e1 sa \u00eds\u0165 aj o \u00farove\u0148 vy\u0161\u0161ie a pomocou dekompil\u00e1tora ho pretransformova\u0165 do nie\u010doho, \u010do je u\u017e ve\u013emi podobn\u00e9 aj zdrojov\u00e9mu k\u00f3du a be\u017en\u00fdm programovac\u00edm jazykom, ako napr\u00edklad C++. \u010ci\u017ee s\u00fa tam tak\u00e9to medzikroky a my sa nepozer\u00e1me len na jednotky a nuly, ale u\u017e na in\u0161trukcie a pr\u00edkazy a tie si prech\u00e1dzame. Potom u\u017e len z\u00e1le\u017e\u00ed od toho, do akej h\u013abky chceme \u00eds\u0165. Ak s\u00fa tam st\u00e1tis\u00edce riadkov, nem\u00e1 zmysel, aby sme i\u0161li do \u00fapln\u00e9ho detailu a str\u00e1vili nad t\u00fdm pol roka. Reverzer sa s\u00fastred\u00ed iba na podstatn\u00e9 \u010dasti, preto\u017ee niektor\u00e9 veci sa opakuj\u00fa a dobre pozn\u00e1me, \u010do robia.<\/p>\n\n\n\n

    Zvedavos\u0165 je asi jeden zo z\u00e1kladn\u00fdch soft skillov. \u010eal\u0161\u00edm je t\u00fa\u017eba neust\u00e1le sa u\u010di\u0165, aj ke\u010f to znie ako kli\u0161\u00e9, ale u n\u00e1s to naozaj plat\u00ed. Samotn\u00e9 IT sa vyv\u00edja ve\u013emi r\u00fdchlo, ale u n\u00e1s to plat\u00ed dvojn\u00e1sobne. My sa s \u00fato\u010dn\u00edkmi vlastne hr\u00e1me na ma\u010dku a my\u0161. Sna\u017e\u00edme sa pochopi\u0165 ako funguje malv\u00e9r, ak\u00e9 techniky vyu\u017e\u00edvaj\u00fa \u00fato\u010dn\u00edci. Naopak, \u00fato\u010dn\u00edci vym\u00fd\u0161\u013eaj\u00fa st\u00e1le nov\u00e9 techniky, aby obi\u0161li na\u0161u detekciu a aby sa im \u00fatok podaril. To znamen\u00e1, \u017ee sa v\u00fdskumn\u00edk nebude nudi\u0165, no vy\u017eaduje si to neust\u00e1le vzdel\u00e1vanie. <\/p>\n\n\n\n

    \u010co sa t\u00fdka hard skillov, z\u00e1kladn\u00fd jazyk, v ktorom fungujeme, je assembly. To je ten medzikrok medzi klasick\u00fdmi programovac\u00edmi jazykmi a jednotkami a nulami. Assembly jazyk sa u\u010d\u00ed aj na niektor\u00fdch vysok\u00fdch \u0161kol\u00e1ch, av\u0161ak je ur\u010dite menej roz\u0161\u00edren\u00fd ako napr\u00edklad Java, \u010di C++. <\/p>\n\n\n\n

    \u010clovek nemus\u00ed by\u0165 \u0161pi\u010dkov\u00fd program\u00e1tor, toto nie je na\u0161a \u00faloha, ale samozrejme poznanie ka\u017ed\u00e9ho programovacieho jazyka je v\u00fdhodou, preto\u017ee tak \u010dlovek vie pochopi\u0165 fungovanie programov.

V dne\u0161nej dobe internetu sa to v\u0161ak d\u00e1 nau\u010di\u0165 aj samo\u0161t\u00fadiom. \u010clovek sa nem\u00f4\u017ee spolieha\u0165 na to, \u017ee mu v\u0161etko d\u00e1 \u0161kola.

    Ako som spomenul \u0161kola d\u00e1 len nejak\u00e9 z\u00e1klady.

Ten sa s\u00fastre\u010fuje pr\u00e1ve na to, o \u010dom sme sa doteraz rozpr\u00e1vali. Ve\u013ea na\u0161ich kolegov s\u00fa absolventi pr\u00e1ve tohto predmetu, patrili medzi naj\u0161ikovnej\u0161\u00edch a bavilo ich to. No nie je to jedin\u00fd sp\u00f4sob, ako sa ku n\u00e1m dosta\u0165. \u010casto k n\u00e1m prich\u00e1dzaj\u00fa aj \u013eudia cez klasick\u00fd pracovn\u00fd inzer\u00e1t.<\/p>\n\n\n\n
