zsteg: Detect embedded data in a PNG, extracting only prime pixels and inverting bits.

zsteg

$ zsteg --prime --invert ${path-to-image-png}

try on your machine

The command is using a tool called zsteg to analyze an image file in PNG format. Let's break down the command and its options:

zsteg: It is a command-line tool used for detecting hidden data in various media files.
--prime: This option instructs zsteg to search for prime numbers in the data. Prime numbers are commonly used in steganography techniques to hide information.
--invert: This option tells zsteg to invert the colors of the image before analyzing it. Inverting the colors can sometimes reveal hidden information that may be concealed using different color channels or color manipulation techniques.
${path-to-image-png}: This is a placeholder indicating the path to the PNG image file that you want to analyze. You need to replace it with the actual file path on your system.

By running this command, zsteg will analyze the specified PNG image file, searching for hidden data using the prime number analysis technique and inverting the colors for a better chance of uncovering any hidden information.
