The investor filing: Form 8-K of Jan 24, 2024. An 8-K is tied to the incident by the company and the dates, so read it before relying on it. It says: "On December 12, 2023, Hewlett Packard Enterprise Company (the “Company,” “HPE,” or “we”) was notified that a suspected nation-state actor, believed to be the threat actor Midnight Blizzard, the state-sponsored actor also known as Cozy Bear, had gained unauthorized access to HPE’s cloud-based email environment."
Filings
| Agency | Record date | People | In total | Days to notice | Links |

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.
