Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Thegentlemen on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

A leading real estate investment and property management company specializing in multifamily and commercial assets. The data includes a breach involving 111,000 Social Security numbers from the company jrk.com. Responsibility for the publication will lie with both the company itself and the insurance providers servicing it - mash.com (the intermediary) and the primary insurer beazley.com - which fails to properly value its clients’ data and is deliberately ignoring communications in an attempt to avoid payment, thereby putting the company at risk.

Pattern: first filing Apr 4, last Aug 4 (OR) — a 121-day rolling notification. Rolling spreads often mean counsel is filing as thresholds trip per state. Why this link?
