In an email sent to its users on Wednesday evening, the chief technology officer of Artsy—an online platform that offers views into the art world as well as works for sale for prices between “$100 to over $1,000,000,” as its website states—alerted users to “a data security incident that may have impacted your Artsy account data.” The notice, signed by Artsy chief technology officer Daniel Doubrovkine, said the company believed that users’ names, emails, and IP addresses may have been among the data stolen.
