zsteg: Detect embedded data in a PNG, iterating pixels vertically and using MSB first.
$ zsteg --msb --order yx ${path-to-image-png}
try on your machine
This command is using the tool called "zsteg" to extract hidden information from a PNG image located at "path-to-image-png". Here is an explanation of the different parameters used:
- "--msb": This option instructs zsteg to only consider the most significant bit (MSB) of each color channel in the image. The MSB is often modified when hiding information, so focusing on it increases the chances of finding hidden data.
- "--order yx": This parameter specifies the order in which zsteg will scan the image. In this case, it starts scanning from the top-left pixel (y = row, x = column) and proceeds in a row-by-row order.
- "${path-to-image-png}": This is the placeholder for the actual path to the PNG image file that you want to analyze.
By running this command, zsteg will apply its steganalysis techniques to the provided PNG image using the specified options, attempting to detect any potentially hidden information or data within the image.
