[8 minut čtení] Vzali jsme množinu náhodných domén a sledovali, z jakých dalších domén si tyto stránky stahují své komponenty. Potom jsme pátrali po jehlách a červech… Co myslíte, povedlo se nám najít nakažené stránky? V rámci našeho působení provozujeme aplikaci Malicious Domain Manager. S její pomocí se snažíme informovat držitele domén v zóně .CZ o úspěšné kompromitaci jimi provozované webové prezentace. Nejčastějším scénářem, který se v rámci napadení webových aplikací pravidelně opakuje, je situace, kdy si útočníci pronajmou web či IP adresu a provozují na ní nějaký exploit kit, který útočí na známé zranitelnosti komponent, jež uživatelé obvykle využívají při procházení webových stránek (tedy prohlížečů, Javy, Flash playeru apod.). Tuto adresu, kde je exploit kit provozován, pak například pomocí tagu iframe vkládají do napadených webových stránek jako jejich součást.
