ChatBooks photo print service has informed its customers that user information was stolen from their systems following a cyber attack. Data consisting of 15 million user records is now being offered for sale on the dark web.
This breach is part of a spree of leaks from a group of hackers that is now selling over 73 million user records from 11 companies.
The service provides an easy way to create photo books using Instagram and Facebook social media accounts as the source.
Hackers held data for over a month
A hacker group called Shiny Hunters on May 3 started advertising ChatBooks user records on a dark web market, asking $2,000 for 15 million rows of data.
They provided a sample with email addresses, hashed passwords (SHA-512), social media access tokens, and personally identifiable information.
