What is Credential Stuffing?
Credential stuffing is an automated attack that replays username and password pairs leaked from other breaches against your login endpoint, counting on people reusing passwords.
How it works
Bots cycle through millions of stolen pairs at low speed per IP to stay under rate limits. Each success is an account the attacker now controls.
Why it matters for sportsbooks
Replayed logins crack user accounts, drain stored value, and trigger fraud disputes that land on your support queue. For your book, that means margin on every market stay protected and bettors get a fair experience.
How OddsArmor detects it
OddsArmor scores every request against behavioral, network, and device signals, so automated patterns surface even when they imitate real bettors. Suspicious sessions get challenged or blocked before they reach your book.
