Cover6 CTF
A hands-on capture-the-flag practice environment built by Cover6 Solutions. Explore web reconnaissance, crypto and encoding, IPv6, network forensics, SIEM and log analysis, CTI, and Linux fundamentals at your own pace. No team or prior experience is required to begin.
31 Days of Cyber
This year’s Cybersecurity Awareness Month theme is Don’t Make It Easy for Them. All month, we’re releasing new challenges in weekly waves, built around the habits that make an attacker’s job easy — and how to break them.
New challenges appear on the board as each wave opens. Every challenge is tested before it goes live.
Stuck or have a question? Ask in the #ctf room in the Cover6 Discord.

Practice scope
Work only with the challenges, files, accounts, and systems explicitly provided by Cover6. Do not scan, probe, authenticate to, or target any external system. A private address, a technique shown in a challenge, or a tool on your own computer is never permission to test another system.
Where This Goes
The CTF is one stop, not the destination. Take as much of the path as you want, whenever you want.
Play
Choose an approved challenge, follow its instructions, and submit the flag in the CTF platform.
