The Code Mystery

The Code Mystery

  • My friend just handed me a mysterious piece of code, hinting that it's connected to a famous movie. he only shared a quote from the movie: "We had a couple of our programmers who decided it would be a good idea to write a backdoor into the code."
  • Now, I'm on a mission to figure out the movie's name, the movie release year, the aircraft registration number and the aircraft serial number within it, using my OSINT skills.
    • Part 1: movie name.
    • Part 2: movie release year.
    • Part 3: aircraft registration number (noting that the aircraft was manufactured in 1981)
    • Part 4: aircraft serial number (noting that the aircraft was manufactured in 1981)
  • Notes:
    • The flag is case insensitive
    • If the movie name consists of more than 1 word, don't separate between them using spaces or underscores, for example if the movie name is (Example Movie), put (examplemovie) in the flag.
    • Flag format: Xpand{Part1_Part2_Part3_Part4}
