Hokuriku Electric's 550,000 email addresses exposed in contractor breach

Hokuriku Electric's 550,000 affected members face increased risk of phishing and spam targeting their email addresses; the company's reliance on a third-party contractor whose security failed creates liability and operational continuity concerns. The broader breach affecting approximately 380 companies and up to 7,700 records indicates systemic vulnerability in the contractor's infrastructure. Service suspension of the email distribution platform affects both Hokuriku Electric's marketing communications and Nyuzen Town's municipal services; resumption timeline remains unspecified.
