Press / market disclosure — not a breach-notification filing

A media or market posting that confirms an incident but carries no breach-notification fields, so compliance clocks aren't assessable. The summary below is extracted from the coverage — verify against the source.

Evidence ladder

Leak-site claim

Attacker assertion only. Establishes: claim date, group, alleged victim.

Press / market reportThis record

Unlocks: incident narrative, operational impact. Still no compliance clock.

State AG / regulator filing

Unlocks: discovery date, data types, affected count, compliance clock.

SEC 8-K / victim statement

Unlocks: materiality, stated response, full audit trail. Ceiling removed.

Source ceiling

  • incident type + narrative only (may be machine-translated)
  • discovery date
  • materiality
  • affected count
  • data types
  • compliance clock

The ✕ fields stay blank until a regulatory filing or victim disclosure lands.
