After a misconfigured API exposed transaction records for 900,000 consumers, Law & Forensics led the forensic investigation, built the regulatory response, and designed a privacy program that satisfied both the CFPB and three state attorneys general.
The situation
A high-growth digital-payments platform processing billions of dollars in annual transaction volume discovered that a misconfigured webhook integration with a third-party analytics vendor had been transmitting consumer payment-transaction metadata — including merchant names, transaction amounts, partial account numbers, and device identifiers — to an improperly permissioned endpoint for several weeks. Hundreds of thousands of consumers were potentially affected.
The regulatory exposure was immediate and multilayered. The CFPB opened a supervisory inquiry under the Electronic Fund Transfer Act and the Consumer Financial Protection Act. The FTC initiated a non-public investigation under Section 5. Attorneys general in three states each issued civil investigative demands citing violations of their respective consumer data-protection statutes. Each regulator demanded, on different timelines, a forensically documented account of the incident, evidence of full remediation, and a credible commitment to a forward-looking privacy program.
The company had no dedicated privacy function, no documented data-flow inventory, and no prior regulatory examination experience. Its engineering organization was doubling in headcount and releasing new API integrations on a two-week sprint cycle.
Our approach
Law & Forensics organized its response around three concurrent workstreams, each timed to the fastest regulatory deadline.
Forensic investigation and exposure scoping. The team conducted a full forensic analysis of the API integration environment, reconstructing the data flows transmitted to the misconfigured endpoint using API gateway logs, vendor-side ingestion records, and network telemetry. The investigation conclusively scoped the exposure to transaction metadata only — no full account numbers, Social Security numbers, or authentication credentials were transmitted — a finding that was critical to the regulatory outcome. A forensic timeline and data-flow diagram, prepared to evidentiary standards, formed the backbone of every regulatory submission.
Multi-regulator notification and response. Law & Forensics authored all five regulatory response submissions, tailoring the forensic narrative and remediation evidence to each agency's statutory framework and investigative posture. The team coordinated a unified factual record across all submissions to prevent inconsistencies that regulators could exploit, while addressing each agency's distinct legal theories and disclosure obligations.
Enterprise privacy program design and implementation. Working alongside the company's engineering and product leadership, Law & Forensics designed a privacy program built around the company's API-first architecture. The program included a real-time data-flow inventory integrated into the CI/CD pipeline, API integration security standards requiring privacy impact assessments before third-party connections, vendor data-processing agreement templates, a consumer rights fulfillment workflow, and a privacy incident response playbook. The program was designed from inception to satisfy the applicable state privacy-law requirements simultaneously, avoiding the proliferation of parallel compliance programs.
The impact
All five regulatory inquiries were closed without formal enforcement action. The forensic investigation's definitive scoping of the exposure — establishing that no high-sensitivity financial identifiers were transmitted — was the decisive factor in the regulators' decisions not to pursue civil money penalties. Law & Forensics estimated that the combination of a strong forensic record and a credible, independently certified privacy program avoided potential fines in excess of $18 million. The company's new privacy program passed independent certification audit nine months after the incident, and no further data events occurred in the 24-month post-incident monitoring period.
| Metric | Result |
|---|---|
| Estimated regulatory fines avoided | $18M+ |
| Regulators satisfied without enforcement action | 5 (CFPB, FTC, CA, NY, TX) |
| Time to independent privacy program certification | 9 months |
| Recurrent data events in 24-month post-incident window | 0 |
