MetaCTF May 2025 Flash CTF

This free capture the flag (CTF) event is hosted by MetaCTF.com, and will cover challenges in Web Exploitation, Forensics, and more.

There will be 5 challenges, and you will have 2 hours to solve as many as you can.

Participation is individual and free to enter. Although participation is individual, OWASP Delaware will have a private scoreboard. #fancy

Step 0) To join the private scoreboard RSVP at Meetup (a.k.a. "Attend") this event. You will see the scoreboard key upon RSVP.
Step 1) Then register for the CTF at https://mctf.io/may2025
Step 2) From the MetaCTF Dashboard, click "Compete" next to the May 2025 event to access the CTF site.
Step 3) Go to the "Scoreboard" page and click "+ Join a Scoreboard". You will be able to enter the private scoreboard key (from Step 0).
Step 4) During the event join the OWASP Delaware Discord (below) to boast of p0wnage, or to ask for help.

For practice, check out the challenges and solutions from a previous Flash CTF at https://mctf.io/practice. #TheMoreYouKnow

BTW - I was told the private scoreboard key will also work for the (past) April Flash CTF.

During the event we can chat on the OWASP Delaware Discord. Don't know where that is? DM me or another OWASP Delaware chapter co-lead for details.

Disclaimer I saw on the MetaCTF practice CTF: "By signing up for this CTF, you consent to be contacted by MetaCTF or sponsors about their services." ¯\(ツ)/¯

PS: This event might get an optional physical location for those that want to collab IRL. Standby for emails via Meetup for more details (sent to those that RSVP here at Meetup for this event).
