FINRA has launched a Financial Intelligence Fusion Center formalizing regulatory expectations that cybersecurity threat intelligence and fraud detection operations be integrated at FINRA-regulated firms, with particular focus on credential theft and account takeover as primary fraud enablers. This is a governance development with no associated CVE or vendor patch; the action surface is organizational — firms should assess whether security and fraud operations share telemetry and escalation protocols, and produce written joint escalation procedures that would satisfy examiner review. NIST CSF 2.0 Respond functions and NIST SP 800-53 IR-4 provide the audit-ready control narrative framework for demonstrating coordinated capability.
