Protect You SOFTWARE

I know it is almost impossible to produce a software that is fully protected. In this I would like to share my experience in protection.
I developed a program that works in PPCPE and I have made a very good protection system….. I think
The protection system works as fallows:
- when the software is first install it capture the date of the installation
- it reads the device ID
- it ask the user for the program serial number
- I have two way of registering the system either through an SMS or through the web using a GPRS.
- The software combines the three number together using some equations to make it almost impossible to find out what I am collecting… also I use an equation verify if the serial number is OK since we are using SMS and it is very costly to send SMS that contains a wrong serial number
- When the user chose the method to register the number is send to my server and the server send back the activation key to the user PPCPE
- The PPCE will read the SMS and delete it and store this SMS in the database …
The above is to get the activation key
In the software the activation key is produce and I use “if statement” to compare the activation key which is stored in the data base and the one the software produce if they are the same it will execute otherwise it will stop execution
To make it very difficult for the hacker I use pointer in the program and in these pointer I add the protiction key to it and subtract the key the program produce to make the additon equal to zero if the two key are the same
The pointer point to each button and each menu item in the program
I hop this information will help and I welcome any comment

Hmmm, sounds nice...but is it worth all the trouble...especially the SMS route could complicate things, no?
Besides, with good debuggers is it not possible to NOP the check section or jmp it, applying a patch?
I would opt more for a good packer such as Armadillo, and protect it that way. It will obfuscate the code, has debugger protections built-in, splits codes and destructs IAT. Additionally, you could add nanomites to make unpacking even harder. Then use a simple license key system.

Yes you are write .. a good hacker can do that …. But
If you use the method of pointer it is almost impossible to get any thing out of the program and it will be use les for any body to use it
And also it is almost imposable to hack it

But armadillo is only available for x86 Windows. But your message is right, HappyGoat.

pointer protection: piece of cake!
Well, the pointer thing as you describe it does not sound too difficult to hack.
You said your software will take the address for a pointer, add the key the user has entered, and substract the one the program has computed so that it equals to zero.
So, this means that the shift is always the same, so if you can get the entry point for any button, you know which value to add to the key generated by your software. Since you don't obfuscate the code this is a matter of minutes to hack this. :roll:

Re: PROTICT YOUR SOFTWARE
As an old cracker I can tell you that this algo would not be difficult to crack. You are not using EXE file encryption, anti-debugging, integrity checking, and other tricks that are used in good protections like ASProtect. They would take some hours to bypass. And playing with pointers can stop only kiddies. UnlockMe said why.
If a cracker would get one valid question-answer pair, he'll easily convert any program to a fully working version. And your code can be cracked without this knowledge.
- The software combines the three number together using some equations to make it almost impossible to find out what I am collecting…

Funny. Why should the cracker try to "find out what I am collecting"? Why the cracker should be bothered with all this ****? There are easier ways.
also I use an equation verify if the serial number is OK since we are using SMS and it is very costly to send SMS that contains a wrong serial number

Costly SMS? Even in Russia you can get free SMS subscription. I have free SMS + free GPRS + free incoming calls.
Your protection has at least one very thin part that makes it useless. I've seen the similar ideas before. But I would not tell you
And remember:
If it runs, it can be defeated. (c) +Orc

It is very nice to see people participates in a subject. I find it very interesting. And very helpful
I am not going to tell what I do but I am given a point to start to programmer
Chatty
Thanks for bringing this point. I can not find it also
UnlockME
I think it is very difficult to hack.
Imagine in my software I have 36 button and menu item. Each of them has a pointer. Let us say button one has a pointer value equal to 11675 let say it is stored in ptr
My key is 123456789 .. let say it is stored in a string str1
The key in the program is 908070605040302010 …… I use more encryption than that but this is just a demonstration
And let us say it is stored in str2
When you address the button you address it like this
Ptr = ptr – (str1[1]-str2[17])
As I mention I am not going to reveal the protection that I use.. I am only giving a point to start
There is more thing in it I leave it to your imagination ..
Mamaich
In my country each SMS cost the mobile owner 0.1 USD … I am not going to cost hem moony for a wrong entry
…….
I think I know what you are thinking …. If the key is produced in the program I can hack it … I hope the above example clear thing up
……..
if you know any EXE encryption or anti debugging software I will be thankful
……..
thanks every body for your replay
-------------------------
pleas remember I am not Claiming that my sAlgorithm is anti-hacked …. It is only an algorithm for protection that I came with

wwb95, I'm not going to disclose in this forum how to actually hack an exe, but what i can tell you is that pointer-based protection will only stop kiddies as Mamaic says.
a hacker is not always a bad guy, though often they use their knowledge for such purpose, but it is before everything a guy that has an extensive knowledge of development tools, operating system, memory management, ...
I can tell you that if you are going to protect your software with this pointer thing, please send me a link I'll be only too happy to provide it for free to the community with a working "yes-code". 8)

I'll assume that (str1[1]-str2[17]) is always a constant for all Ptrs. Then you can easily find an original button handler (don't ask me how, newbies can check all function addresses, gurus can just look at the code, I'll use a different method), calculate this value and patch a program or write a keygen. And if it is not a constant - the process would not be much more difficult.
if you know any EXE encryption or anti debugging software I will be thankful

I don't know any existing protection. Long time ago I was developing such a project, but due to a lack of time and no investitions I've dropped it.
Here is a crackme - http://mamaich.kasone.com/wz/crackme.rar
and a pre-aplha of protector - http://mamaich.kasone.com/wz/protector.rar
It can compress&encrypt ARM WinCE DLLs and EXE files, has minor anti-debugging tricks and primitive import/export/resources encryption. And thats all that was done. No API, no stolen bytes, no on-the fly decryption, no integrity checking, etc.
I would not publish its source codes nor continue the work.

My advice: give up trying to protect your app. It can't be done; anything can be cracked easily. You're only going to piss off your users when the complex reg scheme starts introducing bugs and instability.
All you really want to do is a simple registration scheme. You have to rely on people's honor.
At Airscanner we wrote a book showing how to crack software, with a couple of chapters on ARM-based cracking for Windows CE. But you can get more info, and better, for free at Kaos' website:
http://ka0s.net/
It has everything you need to get started in Pocket PC reverse engineering.
By the way, it's good to see +ORC referenced in this forum. Mamaich do I know you?

Some time ago I was a regular poster on www.reversing.net and www.reng.ru and reader of fraviamb. Now I don't have time for that.
Maybe you've seen my name in "thanks" sections of some tools.

ZXEvil why are you posting that link on multiple topics? What is that file?

need Maps for co-pilot

I need a Syria or middle east map for my co-pilot program that i use it in my PHOTON
please help me to find a map for syria
Or to find working GARMIN prog for the same mobile by maps for Syria

6. Do not post warez.
If a piece of software requires you to pay to use it, either pay or find your cracks and serials somewhere else. We do not accept warez nor do we permit any member to promote or describe ways in which Warez, cracks, serial codes or other means of avoiding payment, can be obtained.

Keep saves through app update

Please remove if content is unacceptable:
When installing third-party apps, I would like to keep my save files through the update. However, for example with Bloons, my save files cause the game to crash to home screen when I use them instead of the default starting files that come with the torrent. Is there a solution?

I'll try to answer you before this gets removed...
It's gotta be a problem with your apk... Updating to a different version shouldn't mess up saves...
Either way this being a paid game it's probably gonna be removed...
Buy it if you want it to work right

As the previous user said buy the game and you won't have problems.

Stinger Heigh10

Hey guys
I just installed the Stinger Heigh10 Unit in my Jeep 2020 JL. I love this thing it was a major upgrade for my car. It also wasn't cheap. $1600. Its Android based. I have been trying to install some custom apps on there but I cannot gain access to the USB file explorer. There is an app for USB on there, but it is only to play songs or view pics. I can't see any apks i put on the usb stick.
Also the iGO maps. A friend of mine bought the actual SD card for the maps. he made me a copy of the card. it was the exact same contents on his SD card but my unit is not able to read the maps off of the card. I get an error "cannot open the available map files with your license". Is there any way around that? Is there a way to SSH into it or ES file explorer or something like that?
Any help is appreciated.
Thanks in advance

Take care posting, especially asking about pirating apps.

You seem to be asking for methods to use a paid app without paying for it. It is not welcome on XDA. Please read Rule 6:

What a genius u r!! I just said I wanna jail break my device. I didn't inquire about any kind of software or how to get illegal software. I only wanted to know how to install apps on that's all.

I am sorry if I made a wrong assumption. But the part of your post where you ask for methods to make the iGo maps work in your device even though you had not purchased it, made me think so. It is a paid software I believe and by your own statement, you had not paid for it.
I apologise if I am wrong in my assumptions.

I do not believe you were wrong in assumptions, quite clearly;

Right there- "Is there anyway around that" - that being the license error when inserting a copy of igo maps.
The genuine igo option for this unit is $149 - refer https://stingerelectronics.com/products/igo-navigation-add-on-for-elev8-heigh10

Hello, I have some licence keys from broken devices I doesn't need.
They are original Microsoft Licences, no cracks, not generated with a keygen or found somewhere in the WWW.
If you are interested you can contact me.
(@MOD if this offer break the forums rules please delete the text above, I just want to help)
If your license key is stored in your BIOS, can you find it out with "Showkeyplus" (portable Software that can run without installation from an USB Stick)
Drivers for your device you can get at the manufacturers support homepage or you look what hardware components are builded-in and get the newest drivers on their support homepage (from Intel, AMD, Nvidia, Realtek, Broadcom, usw. sometimes they are hard to find. That's the way I install drivers).
DO NOT USE DRIVERS OFFERED FROM OTHER HOMEPAGES! They could be contain malware!
Use "Hardware Info 7.35" to see with hardware is build-in in your device. Don't forget to adjust the program settings using it the first time.
It's also a portable Programm that doesn't need to be installed and can run from an USB Stick.
I hope I could help you and doesn't violated any Forums Rules....
