🏳 Flag Format
Flags follow the format ICO{<value>}.
The full flag including the wrapper is accepted by the system.
🔍 Scanning Scope
Only your personal lab container is in scope. Configure your scanning
tools to target only the path that comes after /lab/.
Example: if your lab URL is
https://ctf.defendguide.com/lab/c8cf8f8b0496865c33ff787b3a31fdf2/
set your scanner base URL to
https://ctf.defendguide.com/lab/<your-token>/ —
not ctf.defendguide.com itself.
Scanning outside your lab path is not permitted.
⚠️ Lab Issues
If your lab is unresponsive or fails to load, use the Reload button on the challenge page. Note: reloading the lab may reset your progress on that challenge.
🚫 No DoS / DDoS
Denial-of-service attacks against the platform or any lab are strictly prohibited. Participants found conducting DoS or DDoS activity will be immediately banned.
