As a penetration tester, you are analyzing a JPEG image that you suspect contains a hidden payload or secret message. Which command would you use to attempt to extract the hidden content from the image if a passphrase is not required?
Using the 'steghide extract -sf image.jpg' command will try to extract any hidden data from the specified image file without requiring a passphrase. If the data were embedded without using a passphrase, the content would be revealed. The command 'steghide info image.jpg' will only display information about whether the file contains embedded data and requires a passphrase; it will not attempt extraction. 'steghide embed -cf image.jpg -ef secret.txt' is the command to embed data into an image file, not to extract it. Lastly, 'jpeginfo -v image.jpg' simply validates the integrity of the JPEG image format and provides details, but it is not capable of extracting hidden content.
