Duben & Associates, Inc., a tax preparation firm, experienced an unauthorized system access on February 11, 2020. A forensic investigation concluded on May 7, 2020 that an unauthorized third party accessed the company's systems and may have acquired client personal information including that of primary filers, spouses, and dependents. The incident was detected due to a higher-than-normal rate of IRS e-file rejections for 2019 tax returns.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
