How Story Mode works. Each chapter is a themed attack you'll see in production. Open it, solve the scenes, then take on the boss. Bosses are 2-step: diagnose the signal, then write the rule. Clear the boss to unlock the next chapter. Every scene links into the generator if you want to tune the rule for your traffic.

Stripe Radar Academy · Story Mode Read the signals. Stop the fraud. A fraud-detective campaign for Stripe Radar — five chapters, eleven scenarios, five boss fights. Every case: diagnose , then prescribe. 1. What's the signal? → 2. Write one rule. Get it wrong and you either miss the attack — or block your real customers. CASE I · Card Testing 0 cards one IP block · 12 minutes · $0.50–$1.20 each Prescription Block if :card_count_for_ip_address_hourly: > 5 and :card_funding: in ("debit","prepaid") CASE II · Stolen Card Friction, not block. Signals on the wire › Stolen card, but renewals kept posting › Risk scores 62, 67, 71 — below a block line Prescription Request 3D Secure if :is_recurring: = true and :risk_score: > 60 CASE III · Sign-up Abuse 200 → 4,800 free signups per day — no payment, nothing to score Prescription — act on structure, not the domain Block if :email_count_for_ip_hourly: > 5 CASE IV · Geo & Shipping $890 watch · Ohio → a Delaware freight forwarder risk 0 The ML model waved it through. The signal is the geometry. Prescription Review if :distance_between_billing_and_shipping_address: > 500 and :amount_in_usd: > 100 FINAL CASE V · Friendly Fraud The cardholder is the fraudster. Why ML can't help › Annual plan used 11 months, then disputed › 3DS won't block them — but it shifts liability Prescription Request 3D Secure if :amount_in_usd: > 200 and :is_recurring: = false Diagnose · Prescribe · Ship the fix Play the campaign.
