Bookstore chain Dymocks has warned customers about a possible data breach that could lead to their personal information leaking onto the dark web.

In an email sent on Friday, the bookseller’s director, Mark Newman, said a possible hack had been discovered two days earlier.

“On Wednesday, Dymocks became aware that an unauthorized party may have access to some of our customer data,” he told customers.

Mr Newman said an investigation was launched to assess what had happened once the breach was discovered.

“While our investigation is ongoing and at an early stage, our cybersecurity experts have found evidence of discussions surrounding the availability of our customer data on the dark web,” he said.

The company said it was unsure how many customers were affected and promised to notify those affected as soon as it had more information.

Customers were warned that their email addresses, phone numbers, postal addresses, genders and dates of birth could be part of the leaked data.
