Section F.2 / In context
Where this filing sits in New York and in 2022
OCR classifies the incident as a hacking or IT incident, with the breached information held in a network server. Hacking/IT Incident is the type recorded on 328 of the 511 New York filings (64%) and on 79% of all filings submitted in 2022. Network Server appears on 49% of New York filings.
No business associate is recorded on the filing; 30% of New York filings do involve one. At 13,344 individuals the breach is 2.5 times the New York median filing of 5,338 and 3.3 times the national median of 4,000 across all 7,884 filings. It sits in the 10,000 to 99,999 band, which holds 1,938 filings.
As of 28 August 2026 the case is listed in the HHS OCR breach portal archive. OCR's closing summary of the case is reproduced in full below.
New York's breach notification statute (N.Y. Gen. Bus. Law 899-aa) requires notice to affected residents in the most expedient time possible and without unreasonable delay, no later than 30 days after discovery. Its attorney general threshold: all breaches (AG, Dept. of State, State Police). The HIPAA Breach Notification Rule ran alongside it: notice to affected individuals and to HHS without unreasonable delay and no later than 60 days after discovery, which is the clock that put this filing on the portal.
Multiplying 13,344 individuals by IBM's $160 customer-PII cost per record (Cost of a Data Breach 2025, the figure the site's calculator uses) gives a modelled $2.14M; the 2026 edition's $192 gives $2.56M. Both are modelled estimates with the method shown, not costs disclosed by Mason Tenders' District Council Welfare Fund. For scale, IBM's 2026 average cost of a healthcare breach is $6.64M, so this filing models at 0.4 times the sector average.
Section F.3 / OCR closing summary
The portal's archived description, in full
Written by the Office for Civil Rights when the case was closed and reproduced verbatim from the HHS export.
Mason Tenders' District Council Welfare Fund, the covered entity (CE), reported that it experienced a ransomware attack that compromised the protected health information (PHI) of 13,344 individuals. The PHI involved included names, Social Security numbers, diagnoses, health insurance information, medications, and other treatment information. The CE notified HHS, the affected individuals, and the media. In its mitigation efforts, the CE implemented additional administrative, technical, and security safeguards to better protect PHI.

Method: individuals affected, as reported by Mason Tenders' District Council Welfare Fund to HHS, multiplied by IBM's customer-PII cost per record (Cost of a Data Breach 2025 Figure 6 and the 2026 edition). No cost has been disclosed by the entity for this filing; the figure is a planning estimate, not a fact about the breach. IBM's per-record figures come from mid-volume breaches and IBM cautions against applying them to breaches involving millions of records; the site's per-record page explains where the multiplication holds and where it breaks down.
Context: IBM's average cost of a healthcare breach is $6.64M in the 2026 report ($7.42M in 2025); the global average across all sectors was $4.44M in 2025.

Source: U.S. Department of Health and Human Services, Office for Civil Rights, Breach Portal (breaches affecting 500 or more individuals), retrieved 2026-08-28. Public domain. Individuals affected and dates as reported by the covered entity.
Portal: ocrportal.hhs.gov breach report. Statutory basis: HITECH Act section 13402(e)(4): the Secretary must post a list of breaches of unsecured protected health information affecting 500 or more individuals. Breaches affecting fewer than 500 individuals are reported to OCR annually and are not posted, so they are not on this register. Status wording follows the portal's two tabs ("Cases Currently Under Investigation" and "Archive") as of 28 August 2026; a filing moves to the archive when OCR closes the case. Modelled costs on this site are a method applied to the reported count, using IBM Cost of a Data Breach per-record figures, and are never a cost disclosed by the entity.
