OnlyLANs

OnlyLANs.ai is a free educational hacking challenge. OnlyLANs now has not 1 but 2 Challenges to test your prompt injection prowess. Solve Level 1 of either challenge to enter a monthly drawing for a FREE JHT course!

Test Your AI / LLM Ethical Hacking Skills
Win JHT Training!

Originally built for the ContinuumCon prompt-injection workshop with Eva Benn and Andrew Bellini, we expanded on the idea and made it publicly available for the world to play!


OnlyLANs Monthly Giveaways

During the first week of each month, a random hacker will be chosen from those completing Level 1 to win a seat in a JHT course. With permission, the winners will be announced here and on our first Friday of the month course launch livestream!

Courses to Win*

*Courses subject to change. Can be exchanged for another course of equal or lesser value… if you ask nicely! ๐Ÿ˜‰
