I don't know how the breach happened but I can leave you the Turknet Sample database shared in the Thread. At the moment we have no better option, the breach was confirmed and Hades promised to disclose the full breach after 30 hours but did not upload the full breach or received a payment of 3 BTC. There is also a possibility that this is a scam. Anyway, enjoy the sample data: You must be logged in to see this link.
