How To Crack Programs Yourself with Offset Comparison Tool. Software cracking groups have been around for a long time. Many people will think that they are unethical because they are defeating the software licensing system to illegally reset a trial software (shareware) or turn it into an fully functional program without having to purchase the license. One may wonder the reason for doing this but most of the time it is not for monetary gain but as a challenge to know how “it works” and to gain more knowledge through unpacking, debugging and analyzing the program.
The cracks that are being released to the public are a proof of concept for a specific version and they don’t normally re- crack it again when a new version of the program is released. Knowing how to crack a program using an available ready made patch, keygenerator or cracked files does not earn yourself the title “software cracker”. Only if you are able to think out of the box and figure out how to bypass the software protection yourself, then you consider yourself as a software cracker. Unfortunately it is nearly impossible to have someone to teach or coach you on how to crack programs other than learning it yourself from cracking tutorials that can be found in You. Tube. Before checking out the advanced cracking tutorials, we can show you a very basic and logical method on how to crack programs yourself based on an old patch that does not work with the latest version. For example, an offset patcher for a program called Vice. Versa Pro v. 2. 5 build 2.
July 2. 01. 3 by Nemo from team Sn. D will not work for the current version 2. The patcher reports “wrong filesize or already patched!”It is possible that the software protection isn’t updated to prevent the patcher from working, but the patcher did not work with the latest version because the program was recompiled, moving the location of the bytes that the patcher supposed to change and failing the CRC3.

Software cracking (known as 'breaking. The most common software crack is the modification of an application's binary to cause or prevent a specific key branch in.
Here is how to detect which bytes are being changed by the patcher and how to re- create a new patcher that could work for the latest version. First you will need to search, download and install the older version of Vice. Versa Pro v. 2. 5 build 2. Then search and use Vice. Versa. Pro. 2. 5. SND. zip to patch the program, with the “Make Backup” checkbox ticked.
Download d. UP2, extract the RAR file with an archiver and run dup. Click on Project menubar and select New.
Software Cracks and Software Cracking. A Crack usually comes in the form of an.exe or.com file. Cracking the Code. HOW TO CRACK ANY SOFTWARE. Now crack any software without purchasing it or one can use any trial version software for longer duration before actually purchasing it.

It is optional to fill up the information in the Patch Info window so that the GUI of the patcher will contain the text rather than blank. Or you can just click the Save button to continue. It is advisable to tick the “Run patch with administrator rights” checkbox because most of the time you’ll need to run the patch from the Program Files directory and it will fail to patch if you do not run it as admin. Right click on an empty space in d. UP2, hover on Add and select [Search and Replace Patch]. You’ll notice that [Search and Replace Patch] will appear in the Patch Script window. Double click on it to open up a new Search and Replace Patch window.

HOW TO CRACK ANY TYPE OF SOFTWARE PROTECTION. In this tutorial you will learn how to crack any type of software protection using W32Dasm and HIEW.
Click compare files button. Now you’ll need to select the original and patch file for the compare module to check for the location of the bytes that was changed by the patcher. Most of the time the original file will have an additional . Click the Compare button once you’ve selected both the original and patched file. Click OK button to close the comparison done popup.
You may see one or a few lines being added to search pattern and replace pattern. Click on the browse button to select the Target File that you want to patch. Click Save. Important Note: You should only see a few search and replace patterns added to the list and not too many until the d. UP2 program hangs. If there’s too many, you may have selected the wrong original or patched file for comparison. The final step is to create your own patch by clicking the Project menu bar, select Create Patch and save it to your hard drive.
You can now install the latest version of Vice. Versa Pro v. 2. 5 build 2. After installation has been completed, copy the patch that you’ve created with d. UP2 to the program’s folder, run it and click the Patch button. This time you should see the message “File Patched! OK”. 1. 3. The patch that you created works!

As you can see from the screenshot below, the program is now licensed instead of using the evaluation period. Remember, the method shown above will work if the software protection is unchanged and provided if you are still able to find the older version of the program which the old patch works on. Final note: You may have noticed that the patcher created by d. UP2 is being detected as a virus by some antivirus software but d.
UP2 program itself is not detected. Rest assured that both d. UP2 and the patcher created by it are free from virus. Think about this, if d. UP2 is capable of creating a virus, shouldn’t the antivirus have detected d. UP2 as virus too?

The Removal of Software Copy Protection. CRACKSFor your benefit, I have again delved into the seedy underbelly of the Internet to help keep you informed of what it has to offer. I submit this report on Cracking for your approval. A Definition. Cracking is defined as the attempt to remove the copy protections inserted into software programs. A program successfully stripped of protections is then known as having been "Cracked". Some of the removed protections include: Time limits - example of this is a 3.
Nag Screen - graphic that appears, at programmer determined intervals, asking you to register the software. Serial Number - the use of an assigned number that is required for the program to function. A Crack usually comes in the form of an . Like a file you download from a software company to correct a bug or add a feature, a Crack patches one or more of the applications . Is This Legal? Similar to the other Internet giveaway, Warez, the legality of Cracks is far from being globally defined.
The most common belief stated online is that it is legal to write, upload and even download a Crack, as long as you don't use it to disable a software title's copy protection. However on 1. 0- 2. U. S. that two separate arrests were made for the "illegal distribution of Cracks."The news article reveals a few interesting points about how the FBI and the SPA had two sites under surveillance for seven months! Wow, it took that long to gather evidence!
The article also states that the SPA found over 1. Lets see, at seven months for every two sites that would take them only 4,9. While it may or may not be illegal to use and distribute Cracks, the legality of actually "Cracking" a piece of software is an entirely different matter. Software License. The legality of reverse engineering software has been established in many parts of the world. In Europe for example, this activity is clearly defined as legal in the European Union Directive.
In the United States, several court cases have ruled that the reverse engineering of software is legal, as long as the motive is not commercial gain. Read more about cases that ruled in favor of the right to disassemble software.
You may have read the above text and said to yourself, "Hey the software license says I am forbidden to decompile the software I own."You're right, it does. Except, you don't "own it". You are being "allowed to license it". The reason for this is so that the company that produced the software can be exempt from any liability resulting from a faulty product. Did that hot new software title format your hard drive?
Nothing the manufacturer can do for you because you do not "own" the title and only legal owners have the right to demand compensation. In reality of course, things are different. Even the standard "Software License" states that depending on where you live, all the previous gibberish "may not apply to you". This does not stop them from saying it however, also you "must agree" to this license or you will not be allowed to proceed with the installment of most software titles. Fish Tales and Hand Grenades.
The computer industry is no corporate slouch when it comes to "telling lies" to deceive the public. Here are just a few examples: 1. Monitor? - Not even 1. I guess they thought the average computer user would not notice the difference in an item that they only stare at all day! Modem? - Sorry, maxes out at 5. USRobotics blames this on FCC regulations, actually the problem is the modem sends too much voltage thru the phone line, limiting speed to 5. But hey, what's one more lie among friends?
CD- rom? - Possibly the greatest flat out, screw you, lie yet - These drives average speeds of between 1. X - 2. 0X and are only able to achieve a rate as high as 3. X. The 3. 0X speed is only attained when the CD has data written all the way to the edges of the disk. Once the outer edge data is read the CD drive slows to half speed. This is why you see CD- ROM Drives labeled as 2. The automobile industry used to treat customers like dirt too, until the day that their utter contempt and disregard for the general public peaked with the release of their "gutter car" line.
This pathetic lineup included the abominations that were to be known as, "gremlin" and "pinto". Note: The mere sight of a gremlin caused other drivers to veer off the side of roads in utter fear of these "moon buggies". But it was the pinto's bad habit of exploding like a hand grenade, that finally brought the auto industry back down to earth. The pinto was as ugly as it was dangerous, which made for great T.
V. The news media wasted no time in gleefully broadcasting video, graphically demonstrating just how awful burning to death in an "ugly car" could be. I can only guess at the event that will provoke the regulation of the computer industry. For the chances of something happening are good, for history has a habit of repeating itself. Sorry for the digresion but I just love to ramble on about all kinds of irrelevant shit. Where to Search. As I state in my article on Warez, you should be able to track down all the info you need regarding this subject by making good use of the many search engines the net has to offer. Astalavista Look no further than this site for that crack that your too lazy to learn to write yourself.
Since the file size of most Cracks are small, around (5- 1. KB), you can find them posted on Usenet, even if your provider does not carry binary newsgroups. Alt. cracks is one group that receives thousands of weekly posts. Update: Cracks are no longer small in the age of broadband, software bloat and huge storage capacities. Usenet is not what it used to be with regards to cracks. Astalavista is your best bet. Incredible though it may sound, there is a program called Oscar, yes the same green thingy from Sesame Street, that you can download containing well over 7,0.
The latest version is Oscar 1. You can also find a lot of lists floating around the net containing thousands of serial numbers. Update: I still have a copy of this on a old hard drive, serial #'s are between 1. But still fun to look through. A Deeper Understanding.
You can find sites online run by would be "Capitalists" who download as many Cracks as they can find and then offer to sell to you for a price. Avoid these places, most of the people who Crack these programs are more than glad to give them away for they are said to be in it for a "deeper understanding."Many people involved in Cracking protection schemes say they are in it for the challenge, as well as, the opportunity to learn more about how programs communicate with the operating system, memory and microprocessor. Cracking a program can be an excellent way to learn about programming since you often need to debug and/or disassemble a program. By doing these things you get to trace or step through the inner workings of the software, as well as, receive a text readout of the source code displayed in assembly language (ASM). I'll talk more about these two cracking methods a little later. Note: ASM is the language used to write the tight, fast code needed for the graphics you see in 3. D video games. You'll find a lot of disdain among Crackers for the software companies use of reusable object code development platforms like Visual C++.
They feel that these type of languages do most of the work for the programmer, who in turn, never learns how to write good code, much less an uncrackable protection scheme. Cracking the Code. There are many different ways to penetrate most software programs protections. I will briefly focus on two of them. HMEMCPY can be used to "trap" valid serial numbers for shareware programs. Using a. debugger such as Soft- Ice, you can set a "breakpoint" on HMEMCPY, so that the debugger pops.
HMEMCPY is called. Now that your serial number, and most likely the correct one are. RAM, a cracker can proceed to "fish" for a valid serial number.
Many shareware programs utilize HMEMCPY for comparisons of serial numbers, and this. Delphi or Visual Basic. The next technique involves disabling jumps and is almost certain to work, IF, you can find them. This cracking method involves disassembling the target programs (. Wdasm 8. 9. 3, or Olly. DBG which, as I stated earlier, outputs the programs source code in assembly language (ASM).
While using disassemblers in this fashion will not likely reveal the actual serial or registration number, it will expose the locations in the code where the softwares protections lurk. Once found, these protections are sometimes easily disabled, allowing for the program to be registered by entering the wrong info or no info at all.
Here is an edited view of disassembled code of a software program produced in one of the windows in Olly. DBG. 0. 04. 84. B1. E8 A2. 40. FDFF... CALL ####3. 2. 0. BB8. 00. 48. 4B1. C0 ...... TEST AL,AL0. B1. 8 .. |. 7. 4 1.
