[original works] adds GOTO instruction to AutoLisp language
« on: March 21, 2020, 01:27:12 AM »
As we all know, lisp has no unconditional jump instructions, and programs can only be executed sequentially. Fas supports unconditional jump instructions, but normal compilers cannot generate them. We can do this indirectly. In the LSP source code to write a special string, compiled into the normal fas program after modification, so you can achieve the purpose of unconditional jump between functions.
See the source code:
(defun c:zhuce()
  (setq zcm (getint "Please enter the registration code:"))
  (if (= zcm 3637)(setq syz_goto 959461169)(princ "Registration code error!"));Jump if the registration code is correct
  (princ)
)
(defun t1 ()(princ "Check registration code")
(exit)
(setq syz_loc1 959461170 ) ;Let the program jump here to start execution
(princ "The registration code is correct. Welcome to use")
  ;Insert the program you want to run here
(princ)
  (princ)
)
Here (setq syz_goto 959461169) and (setq syz_loc1 959461170) are two tokens, the unconditional jump instruction of fas is 57h (decimal 87),
as long as we find the two tokens, calculate the size of the interval between the two tokens, we can modify the jump,
to achieve our purpose.959461169 in hexadecimal in fas is 31709,959461170 is 32709, which is easy to find.
Using winhex to see  tmp.fas is like this:
Offset           0  1  2  3  4  5  6  7            8  9  A  B  C  D  E  F
00000000   0D 0A 20 46 41 53 34 2D  46 49 4C 45 20 3B 20 44      FAS4-FILE ; D
00000010   6F 20 6E 6F 74 20 63 68  61 6E 67 65 20 69 74 21   o not change it!

The modified tmp.fas is as follows:
Offset      0  1  2  3  4  5  6  7   8  9  A  B  C  D  E  F
00000000   0D 0A 20 46 41 53 34 2D  46 49 4C 45 20 3B 20 44      FAS4-FILE ; D

A modified program cannot be decomcompiled correctly because normal lisp does not have goto.Decompilation with a popular decompiler produces the following results:
(vl-ACAD-defun (DEFUN C:ZHUCE() (setq ZCM (GETINT "Please enter the registration code:" ))  (if (= ZCM 3637 ) (PROGN   )(PROGN   )(PROGN   (PRINC "Registration code error!" ) )) (PRINC )  ) )
'C:ZHUCE
(DEFUN T1() (PRINC "Check registration code" ) (EXIT ) (setq SYZ_LOC1 959461170) (PRINC "The registration code is correct. Welcome to use" ) (PRINC ) (PRINC )  )
As you can see, the key jump is not translated.

nice research, baitang36, as always

you often mention 'a popular decompiler', i'm not sure what exactly it is
but how will uncoditional jumping protect your code?
the 'hacker' will simply delete c:zhuce function from the decompiled lsp.

Fas to LSP program is a commercial software written by my friend. It can be converted almost perfectly, and most of the LSP generated can be loaded and run normally. He sells the software for 200 dollars. You can provide an fas file and I will decompile it for you to see

Coolio! I took my first programming course on a IIC. The instructor was aghast and extremely apologetic at course end as he couldnít assign the final grade I had achieved - his grades app would only accept values 0-99. It was then when I knew I was on to something, lol. :lol:

GOTO is more free, you can jump anywhere you want, there are no restrictions.

Did you learn the poems of Petofi Sandor?
<Freedom and love>

Life is precious,

Love costs more.

For freedom's sake,

Both can be thrown!

There was a time when I wanted to learn Fortran but there was no use in my field (civil eng. design) at the time. I canít image learning a programming language whilst simultaneously translating back and forth to another spoken language; yeow. As for the green screens, remember them well. When I bought my first PC (Zenith Z150) I had to choose between green and amber. I went amber as it was unusual at the time and text appeared much crisper.

Why do you say there is no GOTO you can use defun statements, I wrote a bubble sort that required dual defuns for the testing part and looping through the data set. Took a BASIC version and rewrote in lisp.

Ps here is my GOTO Autocad command.

GOTO is a very old programming concept and/or "thing". GOTO is for compiled languages and it is translated by the compiler as a "statement to jump to a specific memory address".  ...stack/heap discussions abound.

NOTE: you can also use GOTOs in windows command scripts too for a good visual aid of how they were used (made code messy and yucky).


The example used in the first post is quite interesting but I agree with VovKa.

You don't see what I mean. My GOTO is executed in the middle of one LSP function to the middle of another.

Agree with you.

Crack means that you are violating people's rights, in other words crackers = hackers = thieves ( burglars ).

I don't know why the admins allow you to post such threads in this esteemed and professional forum that is full of great people !

a crack software can claim itself as "commecial" software! shame

You don't understand me at all. I study conservation, not destruction. It is true that decompilation exists, and I want it to fail!

Ignoring the fact that decompilers exist will not make them go away. baltang36 is posting methods to improve compilations through the use of better programming methods and information. Meaning: use the knowledge (s)he is posting to improve your programs/methods/etc. so your compiled programs are harder to decompile.

Iím going to break into your house. I will lift some property while Iím there but worry not - Iím doing research - I will share with others how I was able to breach your security. In the end your house - and your friendís houses - will be much safer - the property I lifted was merely an education fee.

If I had better locks then you couldn't.  ...Around and around we go.


I agree that people should be nice too--who wouldn't--but I don't ignore that there are bad people. If I used a stick as a door lock to my house; who should I then be angry at if my house gets broken into?

Acknowledging that burglary exists, or studying how a lock works, or wanting a better lock in general is Ďrationalizing burglaryí? Donít be absurd.

I donít agree with compiling lisp code but I donít begrudge the people that want to protect their IP if they feel itís necessary.

Please be patient with my frank questions.

1- If you are really working against decompilation, how could you know the return of functions as you already described in this thread without practicing decompilation yourself?

2- How can I trust what you have described and explained in this thread is not the opposite way for crackers to facilitate their process?
Can you give us a real example proving that ( question No. 2) ?

Finally, I believe that you are trying to get fame in this community for private messages requests asking you for decompliations and of course with paid fees which means that you are lurking behind a very transparent curtain that can't stand for too long for all users to get that truth.

You are not working against me because I don't have any complied programs yet but such a conduct cracks me up and I have seen many professional users publishing their applications for a few dollars and what you are presenting is against humanity and not only against their people's income.

Reverse engineering is not welcome anywhere.

Reverse engineering is really annoying, but it's a technology. We can't ignore it. As a lisp developer, we have to come up with a way to fight it. In fact, I have developed the Fas protector, pfas2. X, and dozens of LISP developers are using it. It can resist all the current decompilations and make it fail. I only sell it for $60.

Its good to approve is that your goal to gain from ( protecting ) compiled programs as I already mentioned in my last reply although you did not prove if what you are discussing deserve to think of.

You did not reply to any of my questions which assure my points is that what you are sharing is just unreal analysis that no one can trust to even trust your applications.

If you purchase fish in a sea then that's your problem but you need to visit a psychologist as soon as possible.  :uglystupid2:

I have shared the practice, and someone has successfully applied this method and made tools. How can I answer you if you still doubt it?

64 hour work week?
Are you working for a capitalist? Marx said that the extension of labor time is an effective way to improve the degree of exploitation.

COVID-19 has brought a crisis to the world. I hope that you and your family can protect yourself very well, pay attention to rest, wash your hands frequently, and go out with a mask. Now we are also working from home. Hope the epidemic will end soon!

Covid-19 is the common enemy of human beings, only by working together.
You have to wear masks when you go out, because there are many asymptomatic infected people in the crowd. They don't get sick themselves, but they can infect others. Wearing masks is the only way to do it.
Take care.
We can go to work normally and leave the city freely, but we must wear masks.

yes i agree too, i notice VLX is not fully compiled, you can see like  FAS4-FILE ; Do not change it!
it seems splits each FAS file? if we open with notepad, the DCL are at the buttom part of the file, is still readable!!
does it mean reading (without decompile) violating the rules?

after all like many free source code forums, i hardly see people sharing VLX or FAS.
IMO, i think @baitang is white hat hacker.
assume you are expert knowledge in LISP and it's core technology, i don't think you need to decompile or violating others VLX os FAS. besides It's hard to study other's codes, every programmers has its own logic & unique styles like LM,MP,EEA etc.  as conclusion: I think you are x10000 faster to write a new code than hacking people's code.

PRO: 1. Helpful as anti-virus
        2. 'Forensic' investigation: if a guy customizes LM's codes selling online. one day a user notice a familiar DCL but author name
            changed it violates LM copyright, the user reports to LM. so baitang helps  decompilation, is it legal or illegal?
        3. helping us extra protection. encourage programmers feel safe to sell their copyrighted VLX
       
CON: 1. next generation virus will be vulnerable like COVID-19
         2. that copycat guy upgrade his VLX. forensic failed!
