CSX, a US rail operator, reportedly had a data security breach exposing employees and retirees personal information. The breach was found to be associated with a software provider, Accellion. A company statement said they notified law enforcement officials of the hack. “To date, this incident has had no impact on business operations or our ability to serve our customers,” CSX said in a statement. A ransomware group called Clop is believed to be involved as they posted shots of the data. CSX changed systems after the attack.
