Visibility

Public ⇒ open self-registration

Workbench mode

Challenge integrity: limit AI-assisted cheating by enforcing a sandboxed solving environment (CTFFactory Workbench). On ⇒ artifact challenges (PCAP, memory, stego, disk, rev, crypto…) open in an isolated online workbench and their files stay inside it, so players can't simply download the file and hand it to an AI. Off ⇒ the files are attached to CTFd as normal downloads.

A public registration link is generated automatically at deploy; self-registration is enabled.

Safety guardrail — always on Every generated scenario is strictly fictional. This safeguard is enforced and cannot be disabled.

All scenarios are fictional
