UPX Neobook protection

Alex · Post by **Alex** » Sun Dec 02, 2007 5:32 am

Hi,

I made a program with Neobook and I was on a forum where I ask to crack this program.
A cracker told me that my program was protect with "UPX" !
And he told me that it wasn't a protection but a compression.

What do you think about that ?

Thanks

Alex

He is right. Since there is a decompressor for UPX it is not much protection.

Yes it is true.
I compress and encrypt (if you choose so for compile).

That means your source code is protected from other eyes.
But is does not protect for copying your EXE and steal it.
Therefor were tools like commercial protection software.
Or you code some neoscript to do similar things.
There were samples here on the forum.

HPW, I don't understand, for example, if in my PUB I write :

Code: Select all

Setvar "[Number]" "1234"

If I Compil, Encrypt and Compress, can you see 1234 ?

Thanks

Where do you see it?

With a HEX editor viewing your EXE?

When you choose encrypt your script gets encrypted and it is no more visible inside a HEX editor.

So this allows some protection for the normal PC-user.

A professional hacker will be mostly able to crack it.

Ok,

A cracker tell me that he used OllyDbg and IDA for cracking the program, what did he see ? Tey always say cracking, but cracking what ?

Thanks

NeoBook's compression/encryption option is not intended to protect your software from hackers. Unfortunately, in my experience there is really very little you can do to prevent a motivated "professional hacker" from stealing your work. Hackers simply believe that being a computer programmer or software designer is not a legitimate way to make a living. You're better off concentrating on the millions of honest people who don't steal software.

I'm not sure if "professional hacker" is the right term. "Professional" implies that being a hacker is a legitimate respected career where one can earn a living. It certainly takes skill to hack software, but it serves no constructive purpose. It's like being a "professional safe cracker" or a "professional pick pocket." Hint: if you can't use your real name, you're probably not a professional anything.
