Threat hunting in fintech is shaped by the specific data flows, regulatory constraints, and attacker economics of financial services. A BNPL platform's card processing pipeline presents a fundamentally different attack surface than an enterprise SaaS product.
Why Standard Threat Hunts Miss Fintech-Specific TTPs
Most threat hunting playbooks are built around enterprise IT attack patterns: credential theft, lateral movement, ransomware deployment. In payment processing environments, the high-value targets are different: card data in transit, authorization bypass, and account takeover at scale.
Mapping ATT&CK to a BNPL Payment Flow
Start by decomposing your payment flow into discrete stages: card data entry, tokenization, authorization request, fraud scoring, and settlement. For each stage, identify the relevant ATT&CK techniques an adversary with financial motivation would employ.
