US Bancorp, the seventh-largest US bank, said LockBit's claim that it had been added to the gang's leak site relates to a "fourth party event that occurred outside" its environment, with no evidence its own systems, networks or data repositories were compromised. LockBit added the bank to its victims list on Thursday morning and threatened to leak data in two weeks, but provided no sample data to substantiate the claim. The episode is the second bank listed on a ransomware leak site this week.
