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. 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. The company informed that payment or credit card information was not present in their database, so it was not impacted.
