Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| Massachusetts Massachusetts OCABR | May 19, 2026 | 16 | No dates to count between | Record |
People is the count the filing gives, residents of the state unless marked total. Days to notice runs from the discovery date the letter states, or from the end of the breach window when no letter states one, to the date on the state's first record of the incident. "Over" marks a count past the days the state's statute allows for notice to residents. The statute's trigger is a question of fact, the days are arithmetic.
The statutes
- Massachusetts: no fixed period to notify residents from knowledge or reason to know of the breach, Mass. Gen. Laws ch. 93H, § 3. Attorney General and OCABR as soon as practicable and without unreasonable delay, every breach.
