Ten pak pochopiteln\u011b nespust\u00edte a je to op\u011bt pr\u016f\u0161vih. Pro\u010d o tom v\u0161em p\u00ed\u0161i? Proto\u017ee se op\u011bt objevuj\u00ed \u010dl\u00e1nky o Confickerovi, co\u017e byl a je z\u00e1ke\u0159n\u00fd malware se v\u0161\u00edm v\u0161udy. Vznikl u\u017e v roce 2008 a dodnes je podle antivirov\u00e9 spole\u010dnosti Chec Point t\u0159et\u00edm nejnebezpe\u010dn\u011bj\u0161\u00edm na sv\u011bt\u011b. Prvn\u00ed a druh\u00e9 m\u00edsto si uzurpuj\u00ed RoughTed a Rig ek. Conficker um\u00ed vyu\u017e\u00edt mezer a d\u011br p\u0159\u00edmo v opera\u010dn\u00edm syst\u00e9mu Windows. Proto jsou hodn\u011b d\u016fle\u017eit\u00e9 z\u00e1platy a aktualizace. I p\u0159esto se stalo, \u017ee se Conficer dok\u00e1zal nabourat i do bavorsk\u00e9 jadern\u00e9 elektr\u00e1rny Gundremmingen. Koncern RWE sice tvrdil, \u017ee bezpe\u010dnost provozu rozhodn\u011b nebyla nijak ohro\u017eena, ale kdo v\u00ed. Vir byl odhalen b\u011bhem chystan\u00e9 p\u0159\u00edpravy kontroly bloku B. A nebyl s\u00e1m, byl tam s n\u00edm nalezen i W32.Ramnit. Conficker se m\u016f\u017ee objevit kdekoli, proto\u017ee je vybudov\u00e1na s\u00ed\u0165 infikovan\u00fdch po\u010d\u00edta\u010d\u016f. Hacke\u0159i jej tak mohou ovl\u00e1dat a zad\u00e1vat jim vlastn\u011b jak\u00fdkoli \u00fakol. Tak\u017ee je jasn\u00e9, \u017ee vir se lidn\u011b m\u016f\u017ee \u0161\u00ed\u0159it i lavinovit\u011b mezi spousty u\u017eivatel\u016f.  Obrana je pro b\u011b\u017en\u00e9ho u\u017eivatele v podstat\u011b jednoduch\u00e1. Jak jsem ji\u017e zm\u00ednil v\u00fd\u0161e, je to pravideln\u00e1 aktualizace syst\u00e9mu a spu\u0161t\u011bn\u00fd antivir. Tyto dva bezpe\u010dnostn\u00ed prvky by m\u011bly proniknut\u00ed viru zabr\u00e1nit.
