A database containing details of more than 20 Million users of a Russian-based online dating website has been allegedly stolen by a hacker and made publicly available for sale through an online forum. The leaked credentials are claimed to be 100% valid in a posting to a paste site. The list of leaked data contains over 7 million credentials from Hotmail, 2.5 million from Yahoo, and 2.2 million from Gmail. 50% of the credentials were for people based in Russia, and 40% came from the European Union.
