網(wǎng)站建設(shè)是指使用標(biāo)識語言（markup language)，通過一系列設(shè)計、建模、和執(zhí)行的過程將電子格式的信息通過互聯(lián)網(wǎng)傳輸，最終以圖形用戶界面（GUI）的形式被用戶所瀏覽。簡單來說，網(wǎng)頁設(shè)計的目的就是產(chǎn)生網(wǎng)站。簡單的信息如文字，圖片（GIF，JPEG，PNG）和表格，都可以通過使超文件標(biāo)示語言、可擴(kuò)展超文本標(biāo)記語言等標(biāo)示語言放置到網(wǎng)站頁面上。
大家都有這樣很煩地經(jīng)歷：可能在網(wǎng)上沖浪時，IE會莫名被被改的希奇古怪了，收藏家也多了
許多什么什么精美照片之類的網(wǎng)址，我后來研究這種網(wǎng)頁，隱藏的很深的，首先發(fā)現(xiàn)它的主頁有這
樣的代碼有引用什么www.coolstarpage.com的代碼，
<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代碼這樣的：
<SCRIPT LANGUAGE="JScript.Encode">#@~^tREAAA==@#@&@!Z O@#@&\mD, WMNdP{JYf;/mMrwD] ...</SCRIPT>
顯然用Microsoft Script Encoder加密JavaScript代碼了，網(wǎng)絡(luò)真好，很快找到了
Decoder for Microsoft Script Encoder（該工具的源代碼有附）改程序的具體機(jī)制及算法詳見：
http://www.virtualconspiracy.com/scrdec.html
【題外話】
Windows腳本加密器(Windows Script Encoder - screnc.exe)是微軟提供給大家加密
html,JScript,ASP等腳本,該工具下載地址：
http://msdn.microsoft.com/scripting/default.htm?/scripting/vbscript/download/vbsdown.htm
微軟沒有提供解密工具，微軟在主頁上這樣說：
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 - 要加密的腳本文件
filename2 - 加密后輸出的腳本文件
舉個例子：
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>
你已經(jīng)看到了加密后的腳本使用了Scripting.Encoder這個COM對象來實(shí)現(xiàn)的。
【言歸正卷】
解密后代碼大致為:

批注（我加上了注解，代碼中Ghost Studio及 http://ghoststudio.yeah.net字符串是我代替用的，其中有些代碼是我自己根據(jù)對Windows的了解而加上去的）
更重要的是可以執(zhí)行一個可執(zhí)行文件
雖然JAVA對Applet的安全作出了限制，但由于瀏覽器或語言漏洞的原因，當(dāng)它與功能比較強(qiáng)大的腳本語言結(jié)合時，這些小應(yīng)用程序�？蓱{借正�；蛟幟氐氖侄螌τ脩�
的機(jī)器進(jìn)行惡意修改，比如修改注冊表，運(yùn)行相關(guān)的DOS命令，在用戶機(jī)器上安裝木馬或激活相關(guān)的應(yīng)用程序，其功能之強(qiáng)大遠(yuǎn)非單純的網(wǎng)頁所能勝任，由此看來，現(xiàn)在網(wǎng)上
所流傳的說什么瀏覽相關(guān)網(wǎng)頁中病毒或者硬盤被格式化也就見怪不驚了。另外，還有一種嵌入式應(yīng)用程序就是ActiveX，是微軟的一種插件技術(shù)，也可以象Applet一樣
進(jìn)行一些針對本機(jī)的操作。現(xiàn)在讓我們了解一下以下代碼編制的機(jī) 理（如果你不了解腳本語言，可僅看看程序修改了哪些注冊表表 項(xiàng)，然后找到 這些表項(xiàng)并修改回來）。
讓我們再來看看這個com.ms.activeX.ActiveXComponent東西是什么？
我的computer時Windows 2000
在目錄 \WINNT\Java\Packages\有一個zip文件Tn9j75np.zip大概5M
里面是一堆的java class
我提供代碼中有將有源文件ActiveXComponent.java代碼大致是：
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對java的支持主要靠這個文件:\SystemDir\msawt.dll（Microsoft AWT Library for Java）
