<p>Challenge:
Santa is currently very busy preparing for Christmas. But he noticed that elves changed his “naughty list.txt” from his SharePoint folder “<a href="https://owaspsi.sharepoint.com/sites/xmas2020/Shared">https://owaspsi.sharepoint.com/sites/xmas2020/Shared</a> Documents”. Can you help him solve the mystery of how did they get access to it?</p>
