Two upstate New York utilities are offering customers a year of free credit monitoring after a software contractor allowed access to their personal information.
New York State Electric and Gas and Rochester Gas and Electric say the information included Social Security numbers and birth dates. The subsidiaries of the international utility company Iberdrola also say some financial institution account numbers were exposed.
As of Monday, there was no sign any of the data had been misused. The companies say the access allowed by an employee at the outside consulting firm was a mistake, not malicious.
They've notified law enforcement and customers about the breach and are doing their own investigation.
The companies have 1.2 million electric and 560,000 gas customers. They haven't said how many accounts may have been compromised.
