A few script files are provided, but mainly two script files are significant:Īfter loading the target binary into the IDA Pro, open the folder where the aforesaid IDA script files are located and execute the pe_sections.idc file in order to extend new functionality into IDA Pro such as binary patching and writing. When downloaded, extract the files in a separate folder on the file system of your machine. The IDC script files can be downloaded from this URL as. So here, the role of special IDA script files comes into light as they are able to modify the byte like OllyDbg as well as write the changes into the executable to make the effect permanent.

The target file will be loaded into the IDA Pro, but we could still not modify the byte sequence of the binary file even if enabling the Patch program option in the Edit menu earlier. An important point to remember: don’t forget to uncheck the Make imports segment option, because some useful data can be lost from the database if this option is enabled. It will ask to create a new database as usual, then we select the PE file option as shown in the following figure. Now, load the target binary into IDA Pro. So, do the following changes and save this file.Īfter saving this file, re-launch the IDA PRO and the moment you change the submenu option in the configuration file, you can notice that Patch program option becomes visible in the Edit menu. Thus, in order make this option visible, open the idagui.cfg configuration file of IDA Pro which is located at Drive: Program FilesIDA PRO Advanced Editioncfg folder and scroll down to find the DISPLAY_PATCH_SUBMENU option which is typically set to NO. You can double check from the Edit menu that no Patch program options appeared.

The patching or editing assembly code features are normally invisible in the IDA Pro. So the only option left is Reverse Engineering this binary and manipulating the sensitive bytes to suit our needs as we shall see in the next sections.

It is probable that we might not have the real password and in such circumstances we can’t proceed without this information. If we enter the correct password as “ ajay” then it shows the congratulations message, otherwise it will issue the wrong password message as following.

We can use any compiler to execute the aforementioned binary source code which makes an executable as binar圜rack.exe, and when we run that file, it will prompt to enter the password. Printf(“Ready to login with: %s”,password) The following code will make the binary executable live as binar圜rack.exe: There is of course no direct method to breach into this application without being authenticated, except to reverse engineer or patch the critical bytes which are responsible for performing validation. This article exposes the demonstration of byte patching over a typical C++ binary which essentially required a user password to validate his identity and let him log into the system, and such confidential information is only provided to the registered person indeed. This operation lists the following tools of the trade:

Besides that, the reverse engineer is supposed to operate the IDA Pro Software IDE features perfectly. This tutorial requires thorough knowledge of Assembly Programming and Hex Code manipulation because patching binary with IDA Pro especially deals with assembly opcode instructions. Ultimately, it is up to your skills and how you apply them as to whether IDA makes your search for vulnerabilities easier. It can only facilitate your attempts to locate software vulnerabilities, bugs and loopholes which are typically utilized by both white hat and black hat professionals. It is really only a static-analysis disassembler tool.

IDA Pro is in fact not designed to modify or patch the binary code to suit your needs like other tools such as OllyDbg and CFF Explorer. IDA Pro is intended to assist you in considering the behavior of a binary by offering us disassembled code. IDA Pro appears to have managed mystical potentials in the reverse engineer’s mind by having the impression that merely opening a binary with IDA will reveal all the secrets of a target file.
