In July 2018, the social bookmarking and sharing service ShareThis suffered a data breach. The incident exposed 41 million unique email addresses alongside names and in some cases, dates of birth and password 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 dehashed.com.
