Cheshunt, U.K. — Major British supermarket chain Tesco plc has reportedly been the victim of a data breach. According to CNBC, hackers have gained access to the personal data of more than 2,000 Tesco customers and posted it online.
Tesco has reportedly deactivated some customers’ online accounts after discovering their login information was posted on a text-sharing website. Hackers reportedly took online login data stolen in other breaches and discovered that many Tesco customers used the same information for their Tesco accounts as they did for other accounts.
In an email, a Tesco spokesperson told CNBC that the company has notified customers who are affected and will issue replacement vouchers.
