Hey, Community, tomorrow is our Conference Day… And, so far, no one has won the competition for the last ticket!
How can you win? Hidden in this audio file is a secret flag: https://www.dropbox.com/scl/fi/dzic9tpvgq5lpbk8h9h3t/BSides-Munich-2025-00001001th-Edition-Ticket-Challenge.wav?rlkey=12tesph969x6sh1hy6i5q4hig&st=sayp8rpo&dl=0 BE THE FIRST ONE to find the hidden flag, and you can win a BSides Munich ticket! If you think you have solved it, send a message to ctf (at) bsidesmunich.org. The contest will be open until Sunday, 2025-11-16, 20:00 CET. Good luck!
