Energy giant ENGIE discloses data breach affecting customers

French energy giant ENGIE, one of the world's largest power and natural gas providers, confirmed that attackers stole customer data after breaching a marketing platform used by business partners.

ENGIE operates in renewable energy, infrastructure, and customer energy supply in 30 countries, employs over 90,000 people, and reported €71.9 billion in revenue last year.

An ENGIE spokesperson told BleepingComputer that it cut off the attackers' access to the compromised platform and that they didn't breach the company's internal systems.

"ENGIE's internal IT systems were not compromised. ENGIE recently identified unusual data access activity within a tool used by partners as part of their customer prospecting activities and the marketing of energy offers," the spokesperson said.

The ENGIE spokesperson didn't say how many customers were affected, but told BleepingComputer the incident is limited to customers in France.
