Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
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.
