Introduction

Binwalk is a powerful tool used for analyzing and extracting data from binary files. However, when running binwalk for the first time, users may encounter an error message indicating that the command 7zz failed to execute. This error can be frustrating, especially for those who are new to binwalk and are eager to start extracting data. In this article, we will delve into the possible causes of the 7zz error and provide step-by-step solutions to resolve the issue.

Understanding the 7zz Error

The 7zz error message typically appears when binwalk attempts to extract data from a file using the 7zz command. However, as you mentioned, 7zz is not a part of the 7zip suite. This discrepancy can be confusing, but it's essential to understand that the 7zz command is actually a part of the p7zip package, which is a separate tool from 7zip.

Possible Causes of the 7zz Error

There are several reasons why the 7zz error may occur:

  • Missing p7zip package: The 7zz command is part of the p7zip package, which may not be installed on your system.
  • Incorrect file path: The error message may indicate that the file path specified in the command is incorrect or does not exist.
  • Permission issues: The user running the binwalk command may not have the necessary permissions to execute the 7zz command.

Solutions to Resolve the 7zz Error

Solution 1: Install the p7zip Package

To resolve the 7zz error, you need to install the p7zip package on your system. You can do this by running the following command in your terminal:

sudo apt-get install p7zip-full

Solution 2: Verify the File Path

Make sure that the file path specified in the binwalk command is correct and exists on your system. You can verify the file path by running the following command:

ls /home/valentin/Documents/extractions/cutie.png.extracted/8702/zip_8702.bin

This command will list the contents of the specified directory and verify that the file exists.

Solution 3: Check Permissions

Ensure that the user running the binwalk command has the necessary permissions to execute the 7zz command. You can check the permissions by running the following command:

ls -l /home/valentin/Documents/extractions/cutie.png.extracted/8702/zip_8702.bin

This command will display the permissions of the file and help you identify any issues.
