FAQ

Why is account takeover such a critical threat for banks?

ATO gives attackers immediate access to sensitive financial information, stored value, and payment mechanisms. Once inside an account, scammers can drain balances, commit application fraud, and set up downstream criminal activity—all while appearing to operate as the legitimate customer.

How are attackers bypassing MFA protections?

Banks are increasingly targeted by reverse-proxy phishing sites that perfectly replicate legitimate login pages. These adversary-in-the-middle techniques intercept real-time MFA codes, enabling attackers to break through defenses that were once considered strong.

Why is SMS toll fraud such a growing issue for financial institutions?

SMS-based 2FA creates a monetizable vulnerability: fake account sign-ups trigger premium-rate SMS verifications, allowing attackers—often in collaboration with rogue telecoms—to generate revenue at the bank’s expense. High-volume bot automation makes this fraud extremely scalable.

What makes new account fraud so costly for banks?

When fraudulent sign-ups succeed, banks face expensive KYC checks, increased operational load, degraded site performance, and higher fraud losses. These resource drains redirect attention away from improving customer experience and genuine user support.
