The photography-sharing network 500px disclosed in a blog post that it was hacked last summer, exposing, among other information, usernames, email addresses, and hashed passwords. The photo site will require all users to reset their account passwords.

“At the same time that 500px had alerted its users of the incident, folks on social media were claiming programming education site DataCamp was also breached, with email, name, bcrypt-hashed password, and potentially location, biography, education, and picture among the data exposed…Meanwhile, The Register has reported both 500px and DataCamp data is available for purchase on the dark web, along with a menagerie of data from other sites.”
