In January 2017, the data science website DataCamp suffered a data breach. The incident exposed 760k unique email and IP addresses along with names and passwords stored as bcrypt hashes. In 2019, the data appeared listed for sale on a dark web marketplace (along with several other large breaches) and subsequently began circulating more broadly. The data was provided to HIBP by a source who requested it to be attributed to “BenjaminBlue@exploit.im”.
