Formed in 2013, Crimson Agents is a DC based recreational security team that competes in various computer security wargames and hacker jeopardy contests. Our team comprised of various professionals seeking to practice and enhance our skills in penetration testing, vulnerability development, computer network defense, forensics, and reverse engineering.

In addition to exploitation based CTFs, we also compete in Wireless CTFs with several members who focus solely in this domain.
