The Bugcrowd team designed and built a badge for DEF CON 26, with five challenges that required participants to use various skills such as cryptography, programming, and problem-solving. The first challenge involved noticing an anagram on the badge, while the second challenge required connecting to the badge via serial and solving a puzzle related to the movie WarGames. The third challenge involved deciphering a message encoded in an image using the programming language Piet, while the fourth challenge required decoding a book cipher using George Orwell's novel 1984. The final challenge led participants to a pool party where they could deliver their team's contact information and individual Shamir shards for verification, with prizes given out as koalas. The team is looking forward to starting early brainstorming work on next year's badge, which they hope will involve more hacking skills.
