The LHC CTF is a community-run capture the flag competition held every year on-site at DEF CON in Las Vegas. Organized entirely by LHC volunteers, it runs throughout the full duration of the conference and operates independently from the official DEF CON CTF.

Open for all#

We welcome all skill levels, from first-time DEF CON attendees to experienced CTF competitors. The challenges are layered, so newcomers can get meaningful wins while veterans still find plenty to chew on. Participants often team up spontaneously on location, making it as much a social experience as a technical one.

How to participate#

Just show up to the Lenely Hackers Club community room at DEF CON and look for the posted info. There are physical components in this CTF. Only solving the challenges of the CTF platform will lead to your disadvantage.

CTF platform#

NOTE: The CTF Platform will be activated on the first day of the conference
