Dixons Carphone, one of the largest European consumer electronics and telecommunication retailers, suffered a major data breach in 2017, but new data related to the incident have been shared.
The situation was worse than initially thought, the company announced on Monday that the security breach affected around 10 million customers, much more than the initial estimate.
“Our investigation, which is now nearing completion, has identified that approximately 10 million records containing personal data may have been accessed in 2017.” reads a statement published by the company.
“While there is now evidence that some of this data may have left our systems, these records do not contain payment card or bank account details and there is no evidence that any fraud has resulted. We are continuing to keep the relevant authorities updated.”
Dixons Carphone discovered in June 2017 an “unauthorised access” to certain data held by the company, it promptly launched an investigation and hired an external firm to shed the light on the case.
The company immediately reported the hack to law enforcement, regulators at the Information Commissioner’s Office and the Financial Conduct Authority.
In June it was estimated that hackers accessed data of 1.2 million people and 5.9 million payments cards used at Currys PC World and Dixons Travel were exposed.
Dixons Carphone assured its customers that no financial data was exposed (pin codes, card verification values and authentication data).
“As a precaution, we are choosing to communicate to all of our customers to apologize and advise them of protective steps to minimize the risk of fraud,” continues the statement. “We are continuing to keep the relevant authorities updated.”
“We continue to make improvements and investments at pace to our security environment through enhanced controls, monitoring, and testing,” Dixons said.
This isn’t the first time that the company suffers a security breach, in 2015 another incident exposed the credit card details of 90,000 Dixons Carphone customers.
Affected customers are anyway potentially exposed to phishing attacks and have to be vigilant.
