Hello! We’ve just launched a new wargame site called damn vulnerable web! It consists only of web challenges, primarily designed for intermediate to advanced players rather than beginners. We hope this wargame helps more people gain deeper and broader knowledge in web hacking :) For now, we’re planning to accept only 300 users initially for open beta testing and capacity checks. Starting from this tweet, we’ll gradually increase the number of allowed sign-ups each week. Your interest and support will be a huge help to our future activities We’ll do our best to deliver even better work going forward. Thank you!

We have successfully published our third research! This research focuses on diving deep into the Spring framework. Spring is an important framework used by many companies. However, since the Spring framework doesn't frequently appear in challenges, we expect many people are unfamiliar with it Through this research, we conducted an in-depth study of the Spring framework centered on case studies - what the Spring framework is and what actual bug cases have occurred. We hope it receives a lot of interest! : )
