Reporting, Documentation, and PCI Forensic Investigator (PFI) Procedures
What the domain tests
Reporting, documentation, and PFI procedures: the PFI role, engagement rules, report content, independence, evidence retention, and communication with acquirers and PCI SSC.
Core rules
- A PCI Forensic Investigator is engaged when a suspected cardholder data compromise is reported, typically by the acquirer or processor. The PFI determines whether CHD was compromised, the root cause, scope, and containment, and reports using the PCI SSC PFI report template.
- Independence and conflict disclosure matter. The PFI must not let remediation consulting compromise findings; distinguish confirmed from suspected conclusions.
- The report should include executive summary, methodology, evidence, timeline, affected entities and locations, data elements, root cause, containment status, recommendations, and appendices with hashes and chain of custody.
- Communicate through a defined point of contact; protect confidentiality and legal privilege; retain evidence per contract and PCI SSC requirements.
Worked example
A PFI confirms a POS memory scraper on 12 terminals and a C2 channel, but cannot prove PAN exfiltration. The report states confirmed malware and memory scraping, suspected exfiltration via the C2, and lists 12 in-scope systems plus the back-office server reached with shared credentials. Reasoning: overclaiming no breach or confirmed theft both fail; the acquirer and brands need calibrated findings.
Traps
Confusing PFI with QSA; assuming the PFI remediates; reporting only to the merchant; requiring a PFI for every incident; giving verbal findings without a written report; omitting evidence-handling appendices.
