U.S. Bancorp said recent claims of data theft by a ransomware gang are related to a breach involving a contractor for a third-party, and do not impact its own systems or network. 

A spokesperson told Recorded Future News that U.S. Bancorp has investigated the claims and traced it back to “a potential cyber incident…related to a fourth party event that occurred outside” of their environment. 

“At this time, there is no evidence that our systems, networks or data repositories were compromised,” the spokesperson said. “We have provided relevant information to law enforcement and continue to support their investigation.”

The claims emerged on Thursday morning, when the LockBit ransomware gang added U.S. Bancorp to its list of victims and threatened to leak data in two weeks. 

U.S. Bancorp initially told Recorded Future News that there was no indication the bank’s systems were impacted and no evidence of unauthorized access to their network.
