Minimal script to extract .jpg files based on magic bytes

jpg_magic.py

import glob

magic_numbers = {'jpg': bytes([0xFF, 0xD8, 0xFF, 0xE0, 0x00, 0x10, 0x4A, 0x46, 0x49, 0x46, 0x00, 0x01])}

for x in glob.glob("*jpg"):
    with open(x, 'rb') as fd:
        file_data = fd.read()
        print("Detected "+str(file_data.count(magic_numbers['jpg']))+" JPG files in file : "+fd.name)
        if file_data.count(magic_numbers['jpg']) > 1:
            print("Trying to extract embedded files")
            for f in range(file_data.count(magic_numbers['jpg'])):
                with open(str(f+1)+".jpg", "wb") as ff:
                    ff.write(magic_numbers['jpg'] + file_data.split(magic_numbers['jpg'])[f+1])
                    print("Generated file : "+str(f+1)+".jpg")
