Initiated in 2003 by a group of individuals under the name HackerzVoice (now HZV), France’s first Hackers Syndicate, leHACK has become the oldest and largest hacker event in France.

This renowned gathering brings together hackers of all backgrounds and expertise, fostering collaboration through lectures and challenges. Attendees, regardless of their skill level, come to exchange knowledge on the latest advancements in IT security, enhancing their understanding and capabilities.

To ensure quality and accessibility, leHACK hosts numerous English-speaking conferences and workshops, attracting a diverse and global audience.

Starting as a small gathering, leHACK has grown exponentially, drawing participants ranging from amateurs to seasoned professionals. Each year, we welcome more distinguished speakers from France and around the world. With an annual attendance of approximately 3,500 participants, leHACK continues to thrive as a cornerstone of the hacking community.
