其实源文件并不复杂，只不过有几串特长字符让人迷惑罢了。查看源文件，没有
进入会员区的调用和链接，故此五行乱码一定是JavaScript的调用和链接。观察
发现函数codeIt是密码计算式，函数dw是输出JavaScript语句，试着把第一行的
F删去，破坏其语句结构发现输出script LANGUAGE="JavaScript">再把gwhqjfW,
\[*;#\[;=EX.ydy%whqjfXD00F删去。输出!-- flag=0 flag2=0 -->由此可得出五
行乱码为
script LANGUAGE="JavaScript">"> <!-- flag=0 flag2=0 -->-> t/script>
script LANGUAGE="JavaScript">" SRC="vpencr.txt"> t/script>
script LANGUAGE="JavaScript">" SRC="vpps.txt"> t/script>
script LANGUAGE="JavaScript">"> t!-- function main() { member=document
.all.username.value pass=document.all.password.value encryption() pass
word() } --> t/script>
script LANGUAGE="JavaScript"> !-- function NewWindow(){window.open("de
ngji.htm","","height=400,width=340,toolbar=yes,directories=yes,status=
yes,scrollbars=yes,resize=yes,menubar=no");} // --> t/script>
当然实际中困难重重,曾头脑发昏地考虑用计算器算出每个nS值—^@^,而且F的值
有出入,应为"<",但已经无关紧要了。
在IE地址栏输入vpencr.txt，vpps.txt，dengji.htm的URL，获得vpencr.txt和v
pps.txt,并证实dengji.htm
的URL正确。
vpencr.txt（密码表）源码
function encryption()
{
mm = "Z"
k = "j"
b = "p"
mmmm = "&"
ccc = "6"
l = "i"
c = "q"
m = "s"
abcd = "m"
o = "n"
u = "z"
e = "d"
gg = "U"
p = "u"
jj = "O"
v = "a"
j = "y"
x = "c"
t = "h"
h = "k"
vv = "C"
*
*
*
*
*
y = "t"
lll = "."
mmm = ","
cccc = "]"
g = "l"
dddd = "{"
eeee = "}"
ffff = ""
gggg = "|"
hhhh = "!"
iiii = "@"
jjjj = "#"
kkkk = "$"
llll = "%"
nnnn = "("
}
希奇，这个密码表我好象在哪见过？:)
vpps.txt源码
function password()
{
if(member==h l g g p m v)
{
if(pass==v y y v x h)
{alert("PASS、、、欢迎来到成员区")
window.location.href = y u lll t y abcd
flag2=1}
}
if(member=="")
{}
else
{
if(flag==3)
{window.location.href = "http://***.***.com"
flag2=1}
if(flag2==1) {}
else
{alert ("现在要格式化你的硬盘！！！！————骗你的，呵呵")
flag=flag 1}
}
}
对照vpencr.txt，member=h l g g p m v=killusa, pass=v y y v x h=attack,
href=y u lll t y abcd=tz.htm。搞定！当然也可把会员区的URL改为window.op
en(y u lll t y abcd,"","location=0");叫他进了会员区也不知道自己在哪个目
录下。
使用密码表好象成了一种潮流，好处很多啦，无须非凡转换，就能使"鸡"＝"鸭"
^@^，只不过当前个人主页没有文件权限，看懂密码表比看懂函数计算式轻易多了
。有一些个人主页就是直接调用密码表，不隐藏地址，很轻易被人copy下分析。
