(Reuters) – The login credentials of more than 412 million users of adult websites managed by California-based FriendFinder Networks Inc. were compromised last month in the biggest hack of 2016, according to the website LeakedSource.com violation notification.
The compromised data includes nearly 340 million credentials for Adultfriendfinder.com, which bills itself as “the world’s largest sex and swinger community,” some 63 million records from the video chat site cams.com and approximately 7 million records from the Penthouse adult magazine site. com, LeakedSource said in a blog post on Sunday.
When asked if LeakedSource’s account was correct, the company provided Reuters with a statement that it had brought in outside experts to help examine the case.
“FriendFinder takes the security of its customers’ information seriously and is in the process of notifying affected users to provide them with information and advice on how they can protect themselves,” FriendFinder said in the statement.
“Our investigation is ongoing, but we will continue to ensure that all potential and substantiated reports of vulnerabilities are reviewed and, if validated, corrected as quickly as possible,” he said.
If LeakedSource’s claims are confirmed, the number of email addresses would be more than 10 times the number exposed in last year’s high-profile hacking website Ashley Madison. This attack sparked class actions and an investigation by the United States Federal Trade Commission.
LeakedSource said it was able to view passwords for 99% of credentials.
He said some 78,301 of the accounts were registered to .mil email addresses, which are used by the US military, and another 5,650 were .gov addresses used by US government agencies.
