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.
A hacker using the online alias "Mastermind" on an online forum used by cybercriminals claims the responsibility of the hack into an unnamed online dating website, according to recent reports.
The leaked credentials are claimed to be 100% valid in a posting to a paste site, and Daniel Ingevaldson, chief technology officer of Easy Solution, said that the list included email addresses from Hotmail, Yahoo and Gmail.
"The list appears to be international in nature with hundreds of domains listed from all over the world," Ingevaldson said in a blog post on Sunday.
"Hackers and fraudsters are likely to leverage stolen credentials to commit fraud not on the original hacked site, but to use them to exploit password re-use to automatically scan and compromise other sites including banking, travel and email providers."
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.
