Nationwide Australian bookstore Dymocks suffered from a data breach incident which leaked customer data being available on the dark web. As it looks into whether its client details have been compromised, national Australian book retailer Dymocks advises its customers to check their bank accounts and change their passwords. The retailer claimed to have learned that one of its system breaches may have occurred. It claimed that evidence of "discussions regarding our customer records being available on the dark web" had been discovered by cybersecurity experts. Customers' date of birth, postal addresses, email addresses, cellphone numbers, genders, and membership card information, such as account numbers and expiration dates, may be affected, according to Dymocks managing director Mark Newman in an email to customers.
