This plugin analyzes imported functions and functions that call them and then groups them by tags: cryptography-related, registry-related, network-related, etc. Such grouping makes it easier to find the part of the code responsible for specific operations. This plugin emulates the execution of disassembled code without the need to run the application under analysis in a debugger. Using this plugin, you can emulate the result of executing any piece of code without the risk of modifying something in the system.

All you need to do is specify the start values of CPU registers. Then you can do a step-by-step execution. This tool can also display input and output data. WinHex is a hex editor that provides a rich set of features and development tools for Windows.

WinHex can display checksums or code of software files, which is something a regular text editor is unable to do. Hiew is a binary file editor focused on working with code.

It has a built-in disassembler for x86, x, and ARM as well as an assembler for x86 and x You can also add plugins e. Fiddler has a built-in hex editor and can generate requests based on a selected request or create a custom request.

In addition, the Request to Code plugin allows you to get ready code that executes requests in C , Visual Basic, or Python. Scylla is an application for dumping a running application process and restoring the PE import table. With its help, you can get a totally restored PE file that can be run by the operating system. Screenshot 7. Scylla interface. Image credit: Stack Exchange. Relocation Section Editor is an application used for editing the relocation table in PE files.

The main purpose of this tool is to modify the relocation table in case of patching relocatable pieces of code. A protected file actually contains the relocation table for the unpacker code only. The relocation table for the real code is usually hidden within the unpacker data. Thus, in case a dump is being recovered, there are two ways to restore the missing relocation table for the real code:. PEiD is one of the best reverse engineering tools to detect the packer. By analyzing entropy, PEiD can detect whether an application is packed.

There are also various useful plugins that help to analyze PE files. These are the nine tools that reverse engineers at Apriorit often turn to when working on Windows reversing projects. As you can see, each of these pieces of software for reverse engineering solves a very unique, specific set of tasks. In the next section, we provide practical examples that display the role and importance of each of these tools in Windows reversing.

As an example, we are going to use a test application that you can download and analyze on your own. At this point, we only need to press the OK button.

Once we do that, IDA Pro provides us with the following results of application analysis:. As you can see, the import table is almost empty. Its upper part shows that it was possible to detect a small piece of code the blue part , and the left part shows which functions were detected in our case, very few.

There is also a set of undetected bytes above the start function. We suppose that the application is packed by means of some packer. PEiD will help us determine which packer was used. To start the scanning process, go to Options , choose Hardcore Scan , and click Save :. Next, select the folder where the application is located. After scanning is complete, we receive the following result:.

As you can see from Screenshot 15, the application is packed using the UPX tool. To unpack it, we are going to use CFF Explorer. After that, we can upload the already unpacked application to IDA Pro and restore the assembler code. We upload our application to IDA Pro once more, and when the system asks us whether to upload symbols from the server, we agree. Here is the result of application analysis in IDA Pro:. See below diagrams for example.

All we need to do is swap prev and next pointers for all nodes, change prev of the head or start and change the head pointer in the end. Skip to content. Change Language. Related Articles. Table of Contents.
