A group of friends from France and Switzerland are making waves in the world of Capture the Flag (CTF) competitions. Dubbed "Soudure au Beurre" (Butter Welding in English), the team has quickly risen through the ranks with their quick thinking and clever strategies.

Members of the team, which includes computer science students and experienced hackers, say their unique team name reflects their ability to "weld" together different skills and techniques to solve complex challenges.

"We like to think of ourselves as the butter in a sandwich," said team leader Balda & Azox. "We may not be the biggest or most flashy, but we always find a way to get the job done."

Soudure au Beurre has won several regional CTF competitions and is now competing in international events. The team credits their success to their strong friendship and ability to work together under pressure.

"We all have different strengths and weaknesses, but we support each other and bounce ideas off each other," said team member Cryptax. "It's a real team effort and we have a lot of fun together."

The CTF community is taking notice of Soudure au Beurre and the team is gaining a reputation for their clever tactics and strategic thinking. As they continue to compete on the global stage, these friends from France and Switzerland are proving that teamwork and friendship can lead to success in any field.
