Does the CPMI-IOSCO 2016 Cyber Guidance contain the phrase 'secure the periphery, protect the core', and if not, where does it originate?
The model correctly identified that the phrase does not appear in the 2016 guidance and correctly pointed toward the 2018 CPMI endpoint-security work — but it attributed the phrase to a 2018 strategy document rather than the 2018 speech from which it actually originates. The model appears to have conflated two distinct 2018 CPMI outputs that share thematic content, substituting the closer-in-kind strategy document for the correct speech source. - Regulator portal (if any cited link is dud): https://www.bis.org
This finding implicates the model's source-attribution logic at the intra-ecosystem level: when the correct source and the asserted source are thematically adjacent outputs from the same organisation in the same year, the model's retrieval or generation step does not reliably distinguish between them. For labs with RAG or web-search integrations, this suggests the citation grounding layer needs finer-grained document-level anchoring, not just organisation- or topic-level matching — two 2018 CPMI outputs on related subjects should not be interchangeable in a citation.
A Technology & Data team that accepts an AI misattribution of the phrase 'secure the periphery and protect the core' to the CPMI wholesale payments fraud strategy — rather than to Cœuré's 2018 speech — may cite the wrong document in internal papers, regulatory submissions, or board-level cyber strategy materials. The practical harm is reputational and credibility-based: a firm that cites a source that does not contain the attributed language, or that mischaracterises the scope of a CPMI policy document, signals inadequate primary-source diligence to any supervisor or auditor reviewing the firm's regulatory competence.
For Payment Institutions firms in multiple jurisdictions, where senior managers are individually accountable for the accuracy of regulatory submissions, misattribution carries a non-trivial personal and institutional risk.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
