Flags

  • We are given an image with a series of Flag icons
  • As we know the flag format if PICOCTF{}, we can get a part of the answer: P I C O C T F {F _ _ _ _ _ _ _ _ T _ F F}
  • This seems more like an OSINT challenge. I searched for "red,white,blue stripes flag" (the icon for T) which led me to this wikipedia page, where I found Tango, and International maritime signal
  • The wikipedia page for International Maritime Signal Flags contain all the icons given in the image and their corresponding alphabets/digits. Use this to decipher the flag.
