# Chubu Electric# data breach# cybersecurity
Key Points
- Chubu Electric said on 4 August that unauthorised access to a system it uses had been confirmed.
- Names and email addresses of about 74,000 people — related bodies, business partners and group staff — may have leaked.
- The company has notified the relevant organisations and partners.
Analysis
The notable part is who was exposed: not retail electricity customers but related organisations, business partners and group employees. Corporate data risk often sits in the contact lists nobody monitors rather than the customer database. Names plus email addresses are enough to run a targeted phishing round, and recipients drop their guard when the sender looks like a familiar counterparty.
