The investor filing: Form 8-K of Apr 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: "As an update to information concerning the Change Healthcare cyberattack contained in the Filed Reports, the Company issued a press release on April 22, 2024, regarding its ongoing data assessment and support for impacted individuals, support for providers and customers with notifications, and Change Healthcare service restoration progress."
Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| SEC Form 8-K SEC Form 8-K | Apr 24, 2024 | Not published | 2 days from breach end | 8-K 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.
