Security training platform
CVE-derived challenges. Locked editable regions. A live exploit suite that must pass on submit. Same code — patch it as a developer, exploit it as a researcher.
Get the full scenario, CVE reference, and constraints. Know what's broken before touching it.
Defender: edit only the vulnerable function. Attacker: write the payload that hits the success criteria.
The exploit suite fires real CVE-based attack vectors. All tests green? Submit for XP.
LeetCode-style. Editable region locked to the vulnerable function. Exploit suite always visible below.
