『第 16 楼』:
一个加密vbs的解密过程--第五次揭锅
使用 LLM 解释/回答一下
【续四】打开decode_5.txt看看,都什么玩意,太让各位失望了,怎么就这点儿内容,没有搞错吧?
for ii=1 to len(b):a=asc(mid(b,ii,1))
if a=d then a=13
if a=f then a=10
if a=j then
a=34
elseif a>=h and a<=m then
a=a+r
elseif a>=k and a<=n then
a=a+s
elseif a>=53 and a<=57 then
a=a+u
elseif a>=48 and a<=52 then
a=a+v
end if
uc=uc+chr(a)
next
uc=rn+c+uc
各位看官,我检讨,我让大家高兴的太早了,其实在上一篇里虽然加入了b=lO+qO,但实际运行中经过一系列 if的筛选,最后还是跟decode_4.txt差不多的一个玩意,不过显得整齐了些,也算是收获,为什么会这样,别忘了咱们是用Intercept(code)替代execute(code),否则execute看到有这么多可执行代码会迫不及待的去执行,那时你即使再手疾眼快的话也比不上惨剧发生的快了,假如你过于手疾眼快按冷启的话,没准坏的就不是瘟痘屎系统了,你得拿着某(几)个硬件在奸商的跪台前哭求:大叔大姨行行好,修理费能不能再降点儿,可怜可怜穷人吧,5555……
唉,够累的了,没办法,接着来吧,小车不倒只管推,继续,把第四锅里的
lO=……
qO=……
b=lO+qO
再放进锅里,外加差不多由 a到 v的变量,然后加上前面的拦截程序,不过怎么加得考虑下,因为目前的代码相当于execute解出一层密文后看到的新指令,它将继续执行这些代码,所以目前的代码实际仍然还处在第一锅execute(y)的运行期内,而执行目前的代码,最后是给uc(b)函数返回值,作为还给当初第一锅execute(uc(lO+qO))括号内的结果,但是如果这个返回值里还有可执行的指令的话,execute(uc(lO+qO))会继续执行,所以现在我们得看看uc这个值到底是个什么东西,所以Intercept必须去截获uc的值,所以代码应改写成这样子的:

将上面的代码保存为Decoding_5th.vbs,运行后uc的值就放在decode_6.txt,这回我保您可以看到有明确含意的东东,您就瞧好吧【待续】

因为有循环执行替换的代码所以建议使用OpenTextFile方法。。。。。。并且应用参数8“追加数据方式”这样虽然会得到重复代码,但可避免遗漏。。
用楼上代码补 end sub 运行后得到的代码似乎有点错误在dyz=后面好像”符号转换错了,另外才看到楼上希望连贴 实在不好意思。。。。

【续四】Open decode_5.txt and take a look, what is this stuff? It's so disappointing to everyone. How come there's only this little content? Did I get it wrong?

Because there is code that executes replacement in a loop, it is recommended to use the OpenTextFile method... Also, apply parameter 8 "append data mode" so that although duplicate code will be obtained, omissions can be avoided...
After running the code above with end sub added, the obtained code seems to have an error. It seems that the " symbol conversion is wrong after dyz=. Also, I just saw that the building above hopes to post continuously. I'm really sorry...

哇,我的妈呀,怎么还是这么乱啊,各位看官,对不起啊,有点累您眼神了,不好意思啊,又让您过早兴奋了。不过还好,都是ASCII码,比b=lO+qO的乱码强,而且这么多,说明密文 b=lO+qO肯定是代进去解码了,尽管有点乱,我开始也是,被两个挨着的execute弄晕过去几次,不过您手头上如果有EmEditor这个文本编辑器的话就没问题,一目了然,UEdit好象不行,尽管UEdit功能比EmEditor多些,但这时它就有点弱智,EmEditor看到的效果和我在引文中标记的差不多,这样您一下子就会发现,实际上这是若干个变量在赋值或字符串,然后带了一个 execute(code),这个是重要的,它将推动程序继续深入地向下一步走,否则到此就停下了,另外最后捎带了一个函数er,里面还引用某个叫rr的函数,不管了,焦点肯定要集中在execute()括号内的东东,那是一些变量在合并字符串,看来不少变量都是上面当中赋过值的,没错就是它了,如果解出码来,兴许就是明文了(底气有点不足),所以还是那么干,设计一个拦截程序Intercept:
Sub Intercept (code)
WScript.Echo code
OutPutFile="decode_7'.txt"
Set objFSO=CreateObject("Scripting.FileSystemObject")
Set objTXT=objFSO.CreateTextFile(OutPutFile,True,False)
objTXT.Write code
objTXT.Close
Set objWSH=CreateObject("WScript.Shell")
objWSH.Run OutPutFile
WScript.Quit
End Sub
用Intercept()去把execute()掉包,获得将要执行的代码,所以把上面的结果改造一下,像这样:

Wow, my god, it's still so messy. Dear readers, I'm sorry. It's a bit tiring for your eyes. I'm sorry to have made you excited too early. But fortunately, it's all ASCII code, which is better than the garbled code of b=lO+qO. And there are so many of them, which means the ciphertext b=lO+qO must have been substituted for decoding. Although it's a bit messy, I was like that at the beginning too. I got confused by two adjacent executes several times. But if you have EmEditor this text editor on hand, it's okay. It's clear at a glance. UEdit doesn't seem to work. Although UEdit has more functions than EmEditor, it's a bit stupid at this time. The effect EmEditor sees is similar to what I marked in the quote. In this way, you will immediately find that actually this is the assignment or string of several variables, and then there is a execute (code ), which is important. It will push the program to go further to the next step. Otherwise, it will stop here. In addition, a function er is brought at the end, which also refers to a function called rr. Regardless, the focus must be on the things inside the parentheses of execute(). It seems that many variables have been assigned above. Yes, it's it. If the code is decoded, it may be the plaintext (a bit lacking in confidence). So I still do that. Design an intercept program Intercept:
Sub Intercept (code)
WScript.Echo code
OutPutFile="decode_7'.txt"
Set objFSO=CreateObject("Scripting.FileSystemObject")
Set objTXT=objFSO.CreateTextFile(OutPutFile,True,False)
objTXT.Write code
objTXT.Close
Set objWSH=CreateObject("WScript.Shell")
objWSH.Run OutPutFile
WScript.Quit
End Sub
Use Intercept() to replace the execute() and get the code to be executed. So transform the above result like this:

Copy the above code and save it as Decoding_6th.vbs, run it, and the result is stored in decode_7.txt. This time I guarantee you will see the true lie. Really, I'm not lying to you. I didn't mean to lie to you before. Don't go away. Oh no, don't look for tomatoes and eggs first. Be patient. Give me some time,I have something to say...Oh my god...【To be continued】

一个加密vbs的解密过程--第七集:凶相毕露
使用 LLM 解释/回答一下
【续六】打开decode_7.txt看看,是不是出明文了:
:execute(uc(dyz)):execute(uc(zcx)):function gt():execute(uc(gtz)):end function:function ei(name,wt):execute(uc(eiz)):end function:function df(wh):execute(uc(dfz)):end function:function bf(wh,wt,da):execute(uc(bfz)):end function:function bi(wh):execute(uc(biz)):end function:function rt(wh,li):execute(uc(rtz)):end function:function wr(rna,rda):execute(uc(wrz)):end function:function rr(rna,pa):execute(uc(rrz)):end function:function ar(file,cg):execute(uc(arz)):end function:function dn(loc,web,ris,min):execute(uc(dnz)):end function:function pr(pcs,gs):execute(uc(prz)):end function:function ec(wt):execute(uc(ecz)):end function:function co(wh):execute(uc(coz)):end function:function rs(sw):execute(uc(rsz)):end function:function hi(sw):execute(uc(hiz)):end function:function gi(ids,fid,eid,fname,furl):execute(uc(giz)):end function:function dw(pcs,fn,furl,kill):execute(uc(dwz)):end function:function us(sw):execute(uc(usz)):end function:function cu():execute(uc(cuz)):end function:function km(sw):execute(uc(kmz)):end function:function cf(wh):execute(uc(cfz)):end function
唉,又让各位失望了,有点乱,不过,且慢,让我们先把它整理一下,看清楚些:
execute(uc(dyz))
execute(uc(zcx))
function gt()
execute(uc(gtz))
end function
function ei(name,wt)
execute(uc(eiz))
end function
function df(wh)
execute(uc(dfz))
end function
function bf(wh,wt,da)
execute(uc(bfz))
end function
function bi(wh)
execute(uc(biz))
end function
function rt(wh,li)
execute(uc(rtz))
end function
function wr(rna,rda)
execute(uc(wrz))
end function
function rr(rna,pa)
execute(uc(rrz))
end function
function ar(file,cg)
execute(uc(arz))
end function
function dn(loc,web,ris,min)
execute(uc(dnz))
end function
function pr(pcs,gs)
execute(uc(prz))
end function
function ec(wt)
execute(uc(ecz))
end function
function co(wh)
execute(uc(coz))
end function
function rs(sw)
execute(uc(rsz))
end function
function hi(sw)
execute(uc(hiz))
end function
function gi(ids,fid,eid,fname,furl)
execute(uc(giz))
end function
function dw(pcs,fn,furl,kill)
execute(uc(dwz))
end function
function us(sw)
execute(uc(usz))
end function
function cu()
execute(uc(cuz))
end function
function km(sw)
execute(uc(kmz))
end function
function cf(wh)
execute(uc(cfz))
end function
这不就几乎要接近于揭开最后一个盖子了嘛。基本是不断的把各种变量代入到uc(b)这个函数内,然后解码,生成指令,做成主程序段和主程序所要用到的各种函数,然后执行解出来的代码,病毒终于露出凶相了。
uc(b)这个函数是关键,就像我们曾经怀疑的那样,它就是解码函数。那么这里出现的许多变量呢,它们就是前面第六锅里我们看到的那堆有点纷乱的东东,因为这里的代码是上次第六锅里中出现的execute()括号内字串合并出来的结果,当execute开始执行这里的代码时,与execute同期出现的那些变量和这些代码是同等地位,相当于我们写程序时先给一些变量赋值,然后却把整个主程序段和所有的函数段都用execute()括起来,这实际上没什么影响。
举例:
Var1="Var1 is defined in Main." ' 先给变量赋值
Execute("MsgBox Var1") '==> MsgBox "Var1" ' 然后把程序放在Execute内执行
Execute("MsgBox uc(Var1)") '==> MsgBox uc(Var1)
Execute "Exe"&"cute("&Chr(34)&"MsgBox uc(rr(Var1) & Var2)"&Chr(34)&")"
'相当于 Execute ( "Execute("MsgBox uc(rr(Var1) & Var2)") "),注意“相当于”,不是可直接运行滴,需考虑如何处理引号中的引号
' 仿Virus的做法,把函数主体也写进execute内,再卖个关子,在函数rr里面定义个Var2变量,但rr用不上,一旦rr执行一次,就能给uc(b)用
Function rr(a)
Execute ("Var2="&Chr(34)&"Var2 is defined in Fuction rr. It is no use for Function rr."&Chr(34)&"&vbCrLf"&":rr=a & "&Chr(34)&"can be ued by Function rr."&Chr(34)&" & vbCrLf")
'<-- Var2="Var2 is defined in Functin rr, It is no use for Function rr" & vbCrLf
'<-- rr=a & "and can be used by Function rr."
End Function
Function uc(b)
Execute ("x="&Chr(34)&"All above can be used by Function uc."&Chr(34)&":"&"uc=b & Chr(10) & Chr(13) & x")
'<-- x="All above can be used by Function uc"
'<-- uc=b & vbCrLf & x
End Function
所以如果我们把Decode_7代码中的各个 execute( uc(...))依次解码后,按对应的位置替代 execute( uc(...)),最后得到就是被加密的明文了,也即 病毒原体。
接下来该考虑具体怎么把各段程序生成出来,主要是 uc(b)这个函数,让我们回顾一下uc(b)函数的来龙去脉,见下图:

在第一次出现uc(b)的时候它没有显含变量 b,通过变量w,x,y,z两次解码,到Decode_4th时,才生成uc(b)的可用形式,那里不仅有 b,还有新定义的差不多 c~v的变量和未定义的 l,而 l到后面Decode_6才赋值,当程序第一次用到它时只好算它空字符,Decode_6之后再次调用uc(b)函数时,记住 l要用Decode_6里的定义了,另外还有个 rn,也是同样处理,鉴于x,y,z,w(似乎)从未被改变过,那么Decode_4的内容基本不变,于是我们不妨这样重新构造函数 uc(b),把Decode_4~6中定义的那些变量都堆放到一起,然后取Decode_4中生成函数返回值 uc的算法片断,码到一块儿,就构成 uc(b)函数的明文形式。
利用得到的uc(b)函数,逐一代入 b,一个一个地得到Decode_7中出现的uc(b)的值,象下面这样:
'*******来自Decode_6的变量赋值
on error resume next
dfz=... ' 变量b的来源
...
l=... ' 计算uc时用
rn=... ' 计算uc时用
...
cfz=... ' 变量b的来源
'*******来自Decode_4的变量赋值
c=vbcrlf:d=... ... v=...
'*******取Decode_4中的程序段,构成函数uc(b),放一个拦截程序Intercept(code)进去
execute( ... &"uc=rn+c+uc"&c&"Intercept(uc)") ' 绿色字就是加的拦截程序
'*******拦截程序Intercept(code),开始
Sub Intercept (code)
ForAppending=8
Create=True
ASCII=0
WScript.Echo code
Set objFSO=CreateObject("Scripting.FileSystemObject")
OutPutFile="decode_8.txt"
Set objTXT=objFSO.OpenTextFile(OutPutFile,ForAppending,Create,ASCII)
objTXT.Write code & vbCrLf & "'" & String(8,"*") & vbCrLf
objTXT.Close
Set objWSH=CreateObject("WScript.Shell")
objWSH.Run OutPutFile
If objWSH.PopUp("是否继续执行?",0,"当心引爆病毒!",276)<>6 Then
WScript.Quit
End IF
End Sub
'*******拦截程序Intercept(code),结束,结果将依次追加到decode_8.txt内
'*******运行原解码程序并拦截
execute(uc(dyz)) ' 修改b值,如dyz、zcx……,逐个运行
每次修改execute(uc(b))的 b,存为vbs再运行,最后打开Decode_8.txt,拷贝每次的结果到Decode_7对应的位置中去,合在一起整个病毒原体就重新构造出来了。
数了数,有23个uc(b),你可以一个一个地简单重复,我就不用干了,因为我要把它们自动地生成并组装起来,欲知后事如何,且听下回分解。【待续】

**** Open decode_7.txt and see if the plaintext appears:
:execute(uc(dyz)):execute(uc(zcx)):function gt():execute(uc(gtz)):end function:function ei(name,wt):execute(uc(eiz)):end function:function df(wh):execute(uc(dfz)):end function:function bf(wh,wt,da):execute(uc(bfz)):end function:function bi(wh):execute(uc(biz)):end function:function rt(wh,li):execute(uc(rtz)):end function:function wr(rna,rda):execute(uc(wrz)):end function:function rr(rna,pa):execute(uc(rrz)):end function:function ar(file,cg):execute(uc(arz)):end function:function dn(loc,web,ris,min):execute(uc(dnz)):end function:function pr(pcs,gs):execute(uc(prz)):end function:function ec(wt):execute(uc(ecz)):end function:function co(wh):execute(uc(coz)):end function:function rs(sw):execute(uc(rsz)):end function:function hi(sw):execute(uc(hiz)):end function:function gi(ids,fid,eid,fname,furl):execute(uc(giz)):end function:function dw(pcs,fn,furl,kill):execute(uc(dwz)):end function:function us(sw):execute(uc(usz)):end function:function cu():execute(uc(cuz)):end function:function km(sw):execute(uc(kmz)):end function:function cf(wh):execute(uc(cfz)):end function
Alas, it disappoints everyone again. It's a bit messy, but wait a minute, let's sort it out first to see more clearly:
execute(uc(dyz))
execute(uc(zcx))
function gt()
execute(uc(gtz))
end function
function ei(name,wt)
execute(uc(eiz))
end function
function df(wh)
execute(uc(dfz))
end function
function bf(wh,wt,da)
execute(uc(bfz))
end function
function bi(wh)
execute(uc(biz))
end function
function rt(wh,li)
execute(uc(rtz))
end function
function wr(rna,rda)
execute(uc(wrz))
end function
function rr(rna,pa)
execute(uc(rrz))
end function
function ar(file,cg)
execute(uc(arz))
end function
function dn(loc,web,ris,min)
execute(uc(dnz))
end function
function pr(pcs,gs)
execute(uc(prz))
end function
function ec(wt)
execute(uc(ecz))
end function
function co(wh)
execute(uc(coz))
end function
function rs(sw)
execute(uc(rsz))
end function
function hi(sw)
execute(uc(hiz))
end function
function gi(ids,fid,eid,fname,furl)
execute(uc(giz))
end function
function dw(pcs,fn,furl,kill)
execute(uc(dwz))
end function
function us(sw)
execute(uc(usz))
end function
function cu()
execute(uc(cuz))
end function
function km(sw)
execute(uc(kmz))
end function
function cf(wh)
execute(uc(cfz))
end function
This is almost close to uncovering the last layer. It's basically continuously substituting various variables into the uc(b) function, then decoding, generating instructions, making the main program segment and various functions needed by the main program, and then executing the decoded code. The virus is finally showing its ferocious appearance.
The uc(b) function is the key, just as we suspected earlier, it is the decoding function. Then there are many variables appearing here, which are the messy things we saw in the sixth pot earlier. Because the code here is the result of the string merging in execute() that appeared in the sixth pot last time. When execute starts to execute the code here, the variables appearing at the same time as execute are of the same status as these codes, which is equivalent to us assigning values to some variables first when writing the program, but then enclosing the entire main program segment and all function segments in execute(). This actually has no effect.
For example:
Var1="Var1 is defined in Main." ' First assign a value to the variable
Execute("MsgBox Var1") '==> MsgBox "Var1" ' Then execute the program in Execute
Execute("MsgBox uc(Var1)") '==> MsgBox uc(Var1)
Execute "Exe"&"cute("&Chr(34)&"MsgBox uc(rr(Var1) & Var2)"&Chr(34)&")"
'Equivalent to Execute ( "Execute("MsgBox uc(rr(Var1) & Var2)") "),Note "equivalent to", not directly runnable, need to consider how to handle quotes in quotes
' Imitate the Virus approach, write the function body into execute, and sell a关子, define a Var2 variable in function rr, but rr doesn't use it. Once rr is executed once, it can be used by uc(b)
Function rr(a)
Execute ("Var2="&Chr(34)&"Var2 is defined in Fuction rr. It is no use for Function rr."&Chr(34)&"&vbCrLf"&":rr=a & "&Chr(34)&"can be ued by Function rr."&Chr(34)&" & vbCrLf")
'<-- Var2="Var2 is defined in Functin rr, It is no use for Function rr" & vbCrLf
'<-- rr=a & "and can be used by Function rr."
End Function
Function uc(b)
Execute ("x="&Chr(34)&"All above can be used by Function uc."&Chr(34)&":"&"uc=b & Chr(10) & Chr(13) & x")
'<-- x="All above can be used by Function uc"
'<-- uc=b & vbCrLf & x
End Function
So if we decode each execute( uc(...)) in the Decode_7 code in turn, and substitute them into execute( uc(...)) at the corresponding positions, the final result is the encrypted plaintext, that is, the virus原体.
Next, we need to consider how to generate each segment of the program specifically, mainly the uc(b) function. Let's review the ins and outs of the uc(b) function, see the following figure:
When uc(b) first appeared, it did not explicitly contain the variable b. Through variables w, x, y, z decoding twice, by Decode_4th, the usable form of uc(b) was generated. There are not only b there, but also newly defined variables of almost c~v and undefined l. And l is assigned a value in Decode_6 later. When the program uses it for the first time, it has to be considered as an empty character. After Decode_6, when the uc(b) function is called again, remember that l should use the definition in Decode_6. There is also a rn, which is handled in the same way. Since x, y, z, w (it seems) have never been changed, the content of Decode_4 is basically unchanged. So we might as well re-construct the function uc(b) like this, pile up those variables defined in Decode_4~6 together, then take the algorithm fragment for generating the function return value uc in Decode_4, and code them together to form the plaintext form of the uc(b) function.
Using the obtained uc(b) function, substitute b one by one, and get the values of uc(b) appearing in Decode_7 one by one, like the following:
'*******Variable assignment from Decode_6
on error resume next
dfz=... ' Source of variable b
...
l=... ' Used when calculating uc
rn=... ' Used when calculating uc
...
cfz=... ' Source of variable b
'*******Variable assignment from Decode_4
c=vbcrlf:d=... ... v=...
'*******Take the program segment from Decode_4, form the function uc(b), put an interception program Intercept(code) in
execute( ... &"uc=rn+c+uc"&c&"Intercept(uc)") ' The green words are the added interception program
'*******Interception program Intercept(code), start
Sub Intercept (code)
ForAppending=8
Create=True
ASCII=0
WScript.Echo code
Set objFSO=CreateObject("Scripting.FileSystemObject")
OutPutFile="decode_8.txt"
Set objTXT=objFSO.OpenTextFile(OutPutFile,ForAppending,Create,ASCII)
objTXT.Write code & vbCrLf & "'" & String(8,"*") & vbCrLf
objTXT.Close
Set objWSH=CreateObject("WScript.Shell")
objWSH.Run OutPutFile
If objWSH.PopUp("是否继续执行?",0,"当心引爆病毒!",276)<>6 Then
WScript.Quit
End IF
End Sub
'*******Interception program Intercept(code), end, the result will be appended to decode_8.txt in turn
'*******Run the original decoding program and intercept
execute(uc(dyz)) ' Modify the value of b, such as dyz, zcx..., run one by one
Each time you modify execute(uc(b))'s b, save it as a vbs and run it, finally open Decode_8.txt, copy the results of each time to the corresponding positions in Decode_7, and combine them together to re-construct the entire virus原体.
I counted, there are 23 uc(b)s. You can simply repeat them one by one, I don't need to do it, because I want to generate and assemble them automatically. To be continued for what happens next.

不知为什么,无法上传附件,就拷贝上面的代码,存为比如 uncover.vbs,然后运行去吧,尽请放心,不会引发病毒的,这也是为什么这个帖子才发出来的原因,因为我可不想搞召回之类的事儿^_^
结果保存在virus.txt,就是病毒的源程序, 噢不,等等,我忘了,在前面第六锅中得到的Decode_6中,还有一个像是错误处理的函数,我查看了一下病毒的明文,发现它几次都用到那个错误处理函数,够诡异的,所以最后的结果还要把那个错误处理函数 function er(sco)补进Virus.txt去,因此完整的结果是:

【Continuation Seven】Let's carry this matter through to the end. Although the viewers have all scattered and no one is reading this post, I'm writing for myself now. I use this nice page layout here, and after writing, I'll copy the web page to keep as a reference for myself. As mentioned above, I need to decode the encrypted virus and restore it to a complete program. The following is my method (there are many methods, different people have different views):

I don't know why I can't upload the attachment. Just copy the above code, save it as, for example, uncover.vbs, and then run it. Please rest assured that it won't trigger a virus. This is also the reason why this post was just published, because I don't want to do things like recall. ^_^
The result is saved in virus.txt, which is the source program of the virus. Oh no, wait a minute, I forgot. In the sixth pot earlier, there is a function that looks like an error handling function in Decode_6. I checked the plaintext of the virus and found that it uses that error handling function several times, which is quite strange. So the final result also needs to add that error handling function function er(sco) to Virus.txt. Therefore, the complete result is:

If any expert is interested, please analyze it for us. I've done the previous work, and now it's your turn to show off?
Oh, I forgot to say, thank you to all the experts, viewers, and moderators for your guidance and points. I can't reply one by one, please forgive me. Actually, I'm still asking others' questions over there, and I haven't had time to thank them yet. I'm doing this here to be well-prepared for when someone helps me solve doubts in the future. Okay, everyone, see U in other places, bye-bye!!!
