THE CHALLENGES

Low-and-Slow Account Creation: Fraudsters created fake accounts gradually over time to stay below volume-based detection thresholds.
Email Enumeration and Tumbling: Attackers generated systematic email address variations and alias techniques to create multiple accounts while appearing legitimate to conventional fraud tools.
Domain Exploitation: Bad actors registered new domains specifically for abuse, using recently created addresses that looked valid but carried high fraud risk – a tactic existing controls weren't built to catch.

THE ARKOSE TITAN SOLUTION

Arkose Email Intelligence Added to Existing Stack: Customer gained multi-vector email risk analysis that evaluated formation patterns, gibberish handles, enumeration sequences, domain age and velocity signals in real time.
Domain-Based Risk Controls: Domain intelligence assessed registration dates and ownership signals, flagging the newly registered domains fraudsters relied on as a primary attack vector.
Validated via Fraudulent Session Testing: Before full deployment, the customer tested Email Intelligence against sessions identified as fraudulent and confirmed effectiveness.
Integrated Multi-Layer Defense: Email Intelligence operated in concert with Arkose Titan's bot detection, device identification, behavioral biometrics and IP intelligence for comprehensive coverage across attack vectors.
