Altenar explains why Synthetic Identity Fraud Challenges Sportsbook Operators

How synthetic identities work

Once registered, these accounts can appear legitimate until unusual betting, payment or promotional activity reveals potential links between them.

Why sportsbooks face challenges as attractive targets

Sportsbooks offer fast onboarding, high transaction volumes, multiple payment methods and promotional incentives, creating an attractive environment for organised fraud. Warning signs can include multiple accounts using the same devices or payment methods, linked IP addresses, similar betting patterns, repeated bonus claims and rapid deposits followed by withdrawals.
