Dating Site Breached: 20M Credentials Stolen

Share Button

A hacker calling himself “Mastermind” is claiming to be in possession of over 20 million credentials for an unnamed dating site. These credentials are claimed to be 100% valid in a posting to a paste site. Included in the list are over 7 million credentials from Hotmail, 2.5 million from Yahoo and 2.2 million from Gmail.com.

The list appears to be international in nature with hundreds of domains listed from all over the world. 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.

A couple of weeks ago we anticipated that criminals will increase spear phishing activity and this incident is an early indication that they are moving in that direction, as the first step is acquiring email databases with a relevant motive.
