One of my friends like to hide data in images.
Help me to find out the secret in image.
Analyse metadata of image with exiftool and extract the thumbnail image with:
$ exiftool -b -ThumbnailImage stego.jpg > image.jpg
It contains a QR code, the decoded content is the flag.
$ zbarimg thumbnail.jpg
flag: d4rk{flAg_h1dd3n_1n_th3_thumbnail}c0de
