U.S. Bank says breach claims related to fourth-party incident

U.S. Bancorp was named by the LockBit ransomware gang as a victim with threatened data leaks, but the bank says the claim traces to a contractor (a fourth‑party event) and that there is no evidence its systems were compromised; law enforcement has been notified. The report notes LockBit provided no proof, summarizes the group's prior activity and takedown efforts, and highlights continued monitoring for data exposure.
