Full timeline through 2026

2024 — third-party copy allegedly exfiltrated; actor claims ~5.3M records (not LSEG core breach)

Unverified claim — treat actor counts cautiously. Throughout April 2024, TechCrunch, SC Media, Cybernews, and related trade outlets reported criminal threats to circulate a large World-Check dataset—World-Check is an LSEG risk-screening product sold to financial institutions, with branding continuity from the Thomson Reuters / Refinitiv era—after actors claimed roughly 5.3 million records. LSEG spokespeople were widely quoted stating the incident was not a security breach of LSEG’s own systems but involved a client or third-party environment where a copy of the Wo Exposed categories include Sanctions / PEP / adverse-media–style screening attributes per product class—specific columns depend on leaked file/version claims. BreachHistory cites approximately 5.3M+ affected records in this row. See the refinitiv2024 and canonical BreachHistory entry.
