Reported by CALIFORNIA AG filing
Martin, Hutchison and Hohman, CPAs experienced a data breach on February 15, 2019, after a partner fell victim to a tech support scam. The attacker gained remote access to a computer containing unencrypted tax documents and client data. The firm contained the incident by disconnecting the device and replacing the hard drive. Client PII, including tax returns, was potentially compromised.
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.
