The investor filing: Form 8-K of Oct 30, 2025. An 8-K is tied to the incident by the company and the dates, so read it before relying on it. It says: "Cybersecurity Incidents On August 14, 2025, BayFirst National Bank (“BayFirst”) was notified of a cybersecurity incident experienced by a third-party provider of marketing services. On October 28, 2025, the third-party provider confirmed that some customer information was exposed by this incident."
Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| SEC Form 8-K SEC Form 8-K | Oct 30, 2025 | Not published | 77 days | 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.
