AI security lab · Supply Chain Attacks
Model registries (MLflow, Weights & Biases, internal registries) track model versions. Hijacking the registry allows an attacker to replace a production model with a malicious one. **Challenge:** An MLflow model registry has weak access controls. Demonstrate how an attacker with read access can escalate to register a malicious model version and promote it to the 'Production' stage, replacing the legitimate model.

Step 1
A live AI target
Each lab is a real language model with its own instructions, guardrails and a secret flag it must protect.
Step 2
You attack it
Talk to it like a red teamer would. Craft prompts, chain techniques and use hints if you get stuck.
Step 3
Capture the flag
Get the model to reveal the flag to solve the lab, earn XP and climb the leaderboard.
Step 4
Then defend it
In labs with Defense Mode, write the hardened system prompt that blocks the attack you just used.
