Top Secure Coder - OWASP Call To Battle February
Limited Capacity seats available

OWASP's first Call-To-Battle Community Challenge will begin on February 26, 2021.
Brought to you by OWASP, hosted by Veracode.

Join Veracode for a virtual challenge in a chance to compete for the title of “Top Secure Coder”. Veracode Security Labs removes the standard/boring approach to secure software coding and teaches modern secure coding practices through interactive web apps using real vulnerabilities that developers exploit and patch. The labs-based approach to developer enablement can improve time to resolve flaws and help developers avoid flaws altogether, improving skills and overall awareness of secure coding practices. 
Join the challenge, invite your friends, and see who can complete the most labs in the shortest amount of time to take home the title.

The Secure Coding Challenge will begin Friday, February 26 at 12pmET and will run until Friday, March 5 at 11:59pmET. Prizes will be awarded to the top 3 individuals who complete the most labs in the shortest amount of time.

1st place - $500 Amazon Gift card
2nd place - $250 Amazon Gift card
3rd place - $150 Amazon Gift card

OWASP Juice Shop Virtual Escape Room - Call to Battle April
Limited Capacity seats available

Our second Call-To-Battle Community Challenge will be held on April 9th, 2021.

* For member discount code contact events@owasp.com

After tragedy strikes at the OWASP Juice Shop, a crack team of investigators are deployed to unravel the mystery. Work through the Juice Shop challenges while solving the puzzle of what happened with your team in the interactive map. Clues will appear and areas unlock as you crack more of the challenges, letting you solve more of the story in this time-limited virtual escape room.

Pre-requisites: None

You will be assigned to a team and given access to the virtual Gather space, and the directions to the Juice Shop instance for the challenge.

Something terrible has happened in the famous BUZZBEE Juice Shop, and the OWASP Juice Shop is connected. Explore the BUZZBEE Juice Shop and the connected OWASP Juice Shop to solve the mystery.

Hints for the OWASP Juice Shop will be available in the BUZZBEE Juice Shop, and achieving challenges in the OWASP Juice Shop will change the BUZZBEE Juice Shop space – providing more hints and clues to the disaster that has unfolded.

You will need to work together with your team to solve both sets of challenges, so while it is useful to have an understanding of pen-testing (to tackle the OWASP Juice Shop) not all of you need that, an understanding of how to puzzle together mysteries is equally valuable!

The space will be open for 12 hours, and you can submit your solutions to the mystery at any time (but only one answer per entrant will be accepted).

Good luck!
