These are OSINT challenges that are based on information found on the Internet surrounding the 2021 Olympics. There is a possibility that information will change over time, such as images on Google Earth, employee jobs, or olympic records, etc. We cannot control these things, but if you feel that is why you can’t find a flag, message us on Twitter at @MaverisLabs and we will see if we can help.
