Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Lockbit5 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: Lockbit5 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.
