• CenterPoint Energy confirmed a cyberattack via exposed API, with customer data stolen
• Threat actor claims 7.49M files including IDs, SSNs, billing data, and transaction records
• Operations unaffected; investigation ongoing, regulators notified, customers to be informed

CenterPoint Energy has confirmed suffering a cyberattack and data theft, days after a criminal advertised the stolen files on an underground hacking forum.

CenterPoint Energy is a large US energy utility company that delivers electricity and natural gas to homes and businesses. It employs roughly 8,800 people and operates around $48.3 billion in assets, as of June 2026.

Recently, a threat actor posted a new thread on a dark web forum, saying they stole 7.49 million CenterPoint files from a poorly secured API, The Register reports. They said that the data included customer names and contact details, billing data, move-in dates, driver’s license information, and the last four digits of Social Security numbers (SSN).

Incurring expenses

No independent investigators have confirmed these claims just yet, and the company said it was investigating the matter. In a new 8-K document filed with the US Securities and Exchange Commission (SEC) on September 14, the company said that it “became aware of an online post by a third party claiming to have obtained a data set containing certain of the company’s customer information.”

It activated its incident response protocols and kicked off an investigation with the help of third-party cybersecurity experts.

“While the investigation remains ongoing, the company has determined that an unauthorized third party obtained personal information relating to a portion of the company’s customers through one of the company’s external facing systems,” the filing reads. “The company is continuing to work with third-party experts to determine the scope of customers and personal information affected by the incident and intends to notify affected customers and regulatory authorities as required by applicable law.” The police and regulatory agencies have been notified.

While the attack did not impact CenterPoint’s operations, which continue as usual, it did incur certain expenses, the company concluded. It stressed that it will likely incur even more expenses as the investigation continues.
