Task: JPEG with a decoy geolocation photo hides an appended AES-encrypted ZIP matryoshka; an EXIF base64 hint points to filenames. Solution: carve the appended ZIP, then recursively open each layer using the reverse of its single inner filename as the AES password until flag.txt (base64) yields the flag.
