2009 febru\u00e1rj\u00e1ban vett\u00fck \u00e9szre az els\u0151 eseteket, b\u00e1r a probl\u00e9ma m\u00e1r korr\u00e1bban n\u00e9ha-n\u00e9ha fel\u00fct\u00f6tte a fej\u00e9t.<\/p>\n

A jelens\u00e9g le\u00edr\u00e1sa:<\/strong>
\nA t\u00e1rhelyre felt\u00f6lt\u00f6tt weboldal kib\u0151v\u00fcl javascriptekkel, ritk\u00e1n php scriptekkel. N\u00e9h\u00e1ny esetben el\u0151fordul a .htaccess f\u00e1jlok fert\u0151z\u00e9se, ilyenkor a rewrite engine-t haszn\u00e1lva t\u00e9r\u00edtik el az oldalt. A .htaccess-es tr\u00f3jai fert\u0151z\u00e9s nagyon ritka, jelenleg \u00fagy t\u0171nik ett\u0151l nem kell tartani, de az index.html, index.php \u00e9s egy\u00e9b html \u00e9s php f\u00e1jlok v\u00e9g\u00e9re besz\u00fart k\u00e1rt\u00e9kony k\u00f3dok rendszeresek sajnos.<\/p>\n

Mit\u0151l t\u00f6rt\u00e9nik meg a fert\u0151z\u00e9s?<\/strong>
\nA probl\u00e9ma kiindul\u00f3 pontja a webmester v\u00edrusos sz\u00e1m\u00edt\u00f3g\u00e9pe, ahol be van \u00e1ll\u00edtva az ftp programba az ftp kapcsolati adatok (ftpc\u00edm, felhaszn\u00e1l\u00f3n\u00e9v, jelsz\u00f3). Ennek a h\u00e1rom adatnak a birtok\u00e1ban teljesen leg\u00e1lis m\u00f3don lehet kapcsol\u00f3dni ftpre \u00e9s lehet felt\u00f6lteni, vagy karbantartani a weboldalt. A v\u00edrus kilopja a 3 adatot \u00e9s elk\u00fcldi egy hacker h\u00e1l\u00f3zatnak (botnet). A botnet kiosztja a feladatot n\u00e9h\u00e1ny megfert\u0151z\u00f6tt m\u00e1sik g\u00e9pnek (zombi). A feladat az, hogy csatlakozzon a megadott ftp c\u00edmre, n\u00e9zzen k\u00f6r\u00fcl a t\u00e1rhelyen, hogy milyen f\u00e1jlok vannak (index, main stb.. html \u00e9s php f\u00e1jlok), azt\u00e1n ha ilyet tal\u00e1l (t\u00f6bbnyire tal\u00e1l), akkor szedje le, b\u0151v\u00edtse ki a tr\u00f3jai k\u00f3ddal, majd p\u00e1r m\u00e1sodperc m\u00falva t\u00f6ltse fel.<\/p>\n

Egy sz\u00e1jt fert\u0151z\u00e9se \u00edgy kb 20-30 m\u00e1sodperc alatt megt\u00f6rt\u00e9nhet.<\/p>\n

A MEGOLD\u00c1S?<\/strong>
\nAz al\u00e1bbi l\u00e9p\u00e9seket k\u00e9rj\u00fck megtenni: (A sorrendet k\u00e9rj\u00fck betartani!)<\/p>\n

    \n
  1. K\u00e9rj\u00fck, v\u00e1ltoztassa meg ftp jelszav\u00e1t a Control Centerben (weboldal felt\u00f6lt\u00e9s, ftp adatok ikon alatt)<\/li>\n
  2. Kapcsolja vissza az ftp hozz\u00e1f\u00e9r\u00e9st ugyanezen a fel\u00fcleten (ha kikapcsolat \u00e1llapotban van)<\/li>\n
  3. Az \u00faj jelsz\u00f3t ne mentse le az ftp programj\u00e1ban, csak csatlakoz\u00e1skor adja meg k\u00e9zzel.<\/li>\n
  4. V\u00edrustalan\u00edtsa sz\u00e1m\u00edt\u00f3g\u00e9p\u00e9t.<\/li>\n<\/ol>\n
