Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group LockBit 3.x on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Sanctions caution: LockBit 3.x carries US sanctions exposure — OFAC has designated the group or its operators. Public reporting is permitted (informational-materials exemption, 50 U.S.C. § 1702(b)(3)) — but any payment or material support may violate sanctions. Consult counsel before engaging.

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

Press / market report

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.

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.
