Verticalscope.com and all of their domains were hacked in February of 2016. LeakedSource has obtained and added a copy of this data to its ever-growing searchable repository of leaked data.
This data set contains nearly 45 million records from over 1100 websites and communities. Some of the larger domains include Techsupportforum.com MobileCampsites.com Pbnation.com and Motorcycle.com. Each record may contain an email address, a username, an IP address, one password and in some cases a second password. We added this data set to LeakedSource on April 27th 2016 but only analyzed it now.
Given the massive scale of this breach, it is also likely that VerticalScope stored all of their data on interconnected or even the same servers as there is no other way to explain a theft on such a large scale. ZDNET reporter Zack Whittaker contacted VerticalScope on our behalf and they confirmed the breach in addition to our verification from May.
Passwords were stored in various encryption methods but less than 10% of the domains which account for a very small amount of leaked records used difficult to break encryption (less than a couple million). Most of the records (over 40 million) were just MD5 with salting and this is insufficient.
