CTF challenges.

Capture-the-flag style problems across difficulty levels. Request access to take part.

Challenge tracks stay connected to intake and guided training, not isolated toy labs.

Easy

Phish or legit?

Five emails. Three are phishing. Find them in under 10 minutes.

Medium

A pcap with one beacon hiding in the noise. Identify the C2 and its TTPs.

Hard

Escape a hardened container, escalate to root, and read the flag.

Insane

Eight-hour live exercise. Real timeline, real artifacts, scored team play.
