Australian utility provider Sumo has suffered a data breach, the company has confirmed, with customers’ personal information, including credit scores and licence numbers, posted online.
“On Monday evening, 13 May 2024, Sumo became aware of an incident where customer data was accessed by an unknown person via a third-party file storage application used by Sumo. We can confirm that none of Sumo’s systems were affected,” Fitzalan said in the email to customers, seen by this masthead.
“After being informed of the incident late on Monday, Sumo has acted rapidly to investigate and secured the third-party application.“We deeply apologise to all customers affected by this. We are in the process of writing to all affected customers to inform them and explain the support we will provide.”
“Data protection is extremely important to us. We have investigated and assessed the incident, and are reporting it to the Office of the Australian Information Commissioner. We will continue to investigate whether the information is held by other parties,” Fitzalan said in the email to customers.
