The Red Team Association is hosting an attack/defend CTF qualifier event on September 27th from 12 PM to 8 PM PST.

Each team will receive an identical vulnerable system to authenticate to and secure. Teams must identify security vulnerabilities in their assigned system, then use their knowledge to exploit the same vulnerabilities in other teams' systems.

Date: September 27th, 2025 Time: 12 PM - 8 PM PST (8 hours)

Registration: Open until the event begins
Team Size: No limits
Difficulty: Beginner/Intermediate
Technical Requirements: SSH client only
How It Works: Teams receive SSH credentials (key and IP address) to access their assigned vulnerable system. Flags rotate every minute, allowing teams to submit flags continuously for points. Teams are penalized for taking their services offline, so maintaining system availability while securing vulnerabilities is crucial.
Qualification: The top 50 teams will be invited to compete in the multi-day InfiniteCTF Main Event on November 7th-8th.

The Main Event is online and features significantly more systems and challenges ranging from beginner to advanced difficulty.

The first place team will receive 5 Flipper Zeros, thanks to our sponsor Casco (https://casco.com).
