More than 412 million adult-website credentials hacked

Login credentials for more than412 million users of adult websites run by California-based FriendFinderNetworks Inc. were compromised last month in the largest hack of 2016, according to breach notification website LeakedSource.com.

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 fromvideo sex-chat site cams.com and about seven million records from adult magazine site Penthouse.com, LeakedSource said in a blogpublished on Sunday.

Asked if the account from LeakedSource was accurate, the company provided Reuters with a statement saying it had brought in outside experts to help review the matter.

"FriendFinder takes the security of its customer information seriously and is in the process of notifying affected users to provide them with information and guidance on how they can protect themselves," FriendFinder said in the statement.

"Our investigation is ongoing but we will continue to ensureall potential and substantiated reports of vulnerabilities are
reviewed and if validated, remediated as quickly as possible,"it said.

If LeakedSource's claims are confirmed, the number of emailaddresses would account for more than 10 times the numberexposed in last year's high-profile hack of infidelity websiteAshley Madison. That attack prompted class action lawsuits andan investigation by the U.S. Federal Trade Commission.

LeakedSource said it was able to view passwords for 99percent of the credentials.

It said that some 78,301 of the accounts were registered to.mil email addresses, which are used by the U.S. military, andanother 5,650 were .gov addresses used by U.S. governmentagencies.
