Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.

meow
According to ransomware.live, Meow emerged in 2022 (resurfacing aggressively in 2024), initially operating as a RaaS using the Conti v2 codebase before transitioning to a data-extortion-only model — selling stolen data rather than encrypting files — with a heavy focus on US healthcare and medical research organizations.
