A big and final hello for 2025!
We are back for our final round of meetups for this year, and what a year it’s been…. We’ve seen continued amazing authentic organic growth, as well as maintain our consistent chilled and friendly vibes over all our locations, and only have YOU to thank for that! Your dedicated support, contributions and continual feedback is what drives and keeps this beast going, and we only plan to be more ambitious and impactful within your local communities in 2026 🙂 We are very proud to have you within our national infosec community, as well as being part of the wider hacker and defender DEF CON collective global community.
As you may know, we are busy in the background planning not just more editions of BoTs and Dojos, but our Area41 InfoSec Con which returns again, which we are very excited in anticipation to share with you more details in due course.
The whole DC4131 team want to take this opportunity to say a big thank you for sticking with us, we sincerely hope you achieve some chill, reset & recharge over the holiday period, and see the new year in with a bang 💥🎇💖
