This page pretends to be: a generic SaaS login — “Acme Cloud” (this is App A, the FIRST app).
The trick: we’re testing password reuse — using the SAME password on two different apps. One reused password = if any site is breached, the attacker walks into the others.
What to do here (App A):
1 Type any password, e.g. Hunter2!, in the Password box.
2 Click Sign in.
On THIS page you should see nothing from BDR yet — first use of a password is fine.
✅ With VIYUH BDR ON you SHOULD see on App A: nothing (no banner) — this is the first time the password is seen.
👉 Then open App B and type the SAME password. The reuse banner appears on App B. Mark PASS/FAIL on App B.
Use your Acme Cloud account to continue.
