  • De Eindbazen

Eindbazen team was founded March 2011. Most team members have met in real life and knew each other before the team creation. The team consists solely of Dutch members, both students and professionals. As the members are spread throughout the country, they are generally unable to get together physically when participating in a CTF competition, but the team periodically meets for food, beer and hacking.
