I was scrolling through my feed one evening when I came across OpenClaw, an open source personal AI assistant that people were calling everything from “Jarvis” to “a portal to a new reality.” The idea is beautiful: an AI that lives on your machine or in the cloud, talks to you over WhatsApp or Telegram, clears your inbox, manages your calendar, browses the web, runs shell commands, and even writes its own plugins. Users were having it check them in for flights, build entire websites from their phones, and automate things they never thought possible.
My first reaction was the same as everyone else’s: this is incredible.
My second reaction was…different. I started thinking about what happens when that kind of power meets a malicious prompt. What if someone tricks the agent into reading files it should not access? What if a poisoned web page rewrites the agent’s instructions? What if one agent in a multi-agent chain passes bad data to another that blindly trusts it?
Those questions became Season 4 of the Secure Code Game.
The Secure Code Game is a free, open source in-editor course where players exploit and fix intentionally vulnerable code. When I created the first season in March 2023, the goal was straightforward: make security training that developers would enjoy. Fix the vulnerable code, keep it functional, level up. That core philosophy has not changed across any season.
Season 2 expanded into multi-stack challenges with community contributions across JavaScript, Python, Go, and GitHub Actions. Season 3 took players into LLM security, where they learned to hack and then harden large language models. Along the way, over 10,000 developers across the industry, open source, and academia have played to sharpen their skills.
What has changed with each season is the landscape. When we launched Season 1, AI coding assistants were just starting to become mainstream. By Season 3, we were teaching players to craft malicious prompts and then defend against them. Now, with Season 4, we are tackling the security challenges of AI systems that can act autonomously. They can browse the web, call APIs, coordinate with other agents, and act on your behalf.
The timing is not a coincidence. AI agents have moved from research prototypes to production tools at remarkable speed, and the security community is racing to keep up.
The OWASP Top 10 for Agentic Applications 2026, developed with input from over 100 security researchers, now catalogues risks like agent goal hijacking, tool misuse, identity abuse, and memory poisoning as critical threats. A Dark Reading poll found that 48% of cybersecurity professionals believe agentic AI will be the top attack vector by the end of 2026. And Cisco’s State of AI Security 2026 report highlighted that while 83% of organizations planned to deploy agentic AI capabilities, only 29% felt ready to do so securely.
The gap between adoption and readiness is exactly where vulnerabilities thrive. And the best way to close that gap is by learning to think like an attacker.
Season 4 puts you inside ProdBot, your productivity bot, a deliberately vulnerable agentic coding assistant for your terminal. Inspired by tools like OpenClaw and GitHub Copilot CLI, ProdBot turns natural language into bash commands, browses a simulated web, connects to MCP (Model Context Protocol) servers, runs org-approved skills, stores persistent memory, and orchestrates multi-agent workflows.
Your mission across five progressive levels is simple: use natural language to get ProdBot to reveal a secret it should never expose. If you can read the contents of password.txt, you have found a security vulnerability.
No AI or coding experience is needed…just curiosity and willingness to experiment. Everything happens through natural language in the CLI.
Each level of the game mirrors a stage in how real AI-powered tools evolve. As ProdBot gains new capabilities, the upgrade opens a new attack surface for you to discover. Here is what ProdBot looks like as it grows:
Each level builds on the previous one, and that progression is the point.
We aren’t going to tell you exactly which vulnerabilities you will find at each level as that would ruin the fun. But we will say this: the attack patterns you will discover in Season 4 are not theoretical. They reflect the kinds of risks that security teams are grappling with right now as organizations deploy autonomous AI systems into production.
Think about CVE-2026-25253 (CVSS 8.8 – High): Known as “ClawBleed” or the one-click Remote Code Execution (RCE) vulnerability. It allowed attackers to steal authentication tokens via a malicious link and gain full control of the OpenClaw instance.
The goal is not just to learn a specific exploit. It is to build the instinct that helps you spot these patterns in the wild, whether you are reviewing an agent’s architecture, auditing a tool integration, or simply deciding how much autonomy to give the AI assistant that just landed on your team.
This entire experience runs in GitHub Codespaces, so there is nothing to install, nothing to configure, and it doesn’t cost you a penny (Codespaces offers up to 60 hours of free usage per month). You can be inside ProdBot’s terminal in under two minutes, and each season is self-contained, so you can jump straight into Season 4 without covering the earlier ones.
You may find Season 3 to be a helpful foundation since it builds the basics of AI security. But it is not required. Just bring your hacker mindset.

Do I need AI or coding experience to play Season 4?
No. Everything happens through natural language in the CLI. You type plain English, or any language, prompts and ProdBot responds. Curiosity and a willingness to experiment are all you need.
Do I need to complete previous seasons first?
No. Each season is self-contained. You can jump directly into Season 4 by running ProdBot and typing level <N>. That said, Season 3 builds a helpful foundation in AI security and takes about 1.5 hours.
How long does Season 4 take?
Approximately two hours, though it varies depending on how deeply you explore each level. Some players like to try multiple approaches per level.
Is this free?
Yes. The Secure Code Game is open source and free to play. It runs in GitHub Codespaces, which provides up to 60 hours of free usage per month.
What are the rate limits?
Season 4 uses GitHub Models, which have rate limits. If you hit a limit, wait for it to reset and resume. Learn more about responsible use of GitHub Models.
