Data breach at "AKP Emails"

In July 2016, a hacker known as Phineas Fisher hacked Turkey's ruling party (Justice and Development Party or "AKP") and gained access to 300k emails. The full contents of the emails were subsequently published by WikiLeaks and made searchable. HIBP identified over 917k unique email address patterns in the data set, including message IDs and a number of other non-user addresses.
