The company says it does not know how many customers were affected by the data breach. Nissan is contacting all of its roughly 1.13 million current and previous customers. It’s believed that the unknown hacker(s) may have had access to the following information: The company offers 12 months of free credit monitoring services through TransUnion to all of the company’s financed customers. The company has contacted Canadian privacy regulators, law enforcement, and data security experts to help rapidly investigate the matter. It is not clear if the hack also impacts customers outside of Canada and customers did not obtain financing through NCF.
