But the company said in a statement that it had “received a number of reports regarding potential security vulnerabilities from a variety of sources” and was investigating.
“Immediately upon learning this information, we took several steps to review the situation and bring in the right external partners to support our investigation.” the statement said.
Security experts criticised that site for not doing enough to prevent a repeat breach.
David Kennerley, director of threat research at security software firm Webroot, commented: “This attack on Adult Friend Finder is extremely similar to the breach it suffered last year….
It warned of significant attacks — not just to Adult Friend Finder accounts but also those of its sister sites.
The data was stolen last month using a vulnerability exposed around the same time, Leaked Source reported.A hack against popular adult dating and entertainment company Friend Finder Networks exposed data related to more than 412 million user accounts, according to a report from breach notification site Leaked Source.If the report is correct, that would make the breach one of the largest on record in terms of the number of accounts affected.Peter Martin, managing director at cyber security specialist Reliance ACSN, added: “This breach on Adult Friend Finder is the second in as many years, which raises serious alarm bells.It’s clear the company has majorly flawed security postures, and given the sensitivity of the data the company holds this cannot be tolerated.” Download this white paper to learn the 8 ways by which legacy ERP systems hold back your business and how “version-less” cloud ERP can help eliminate costly upgrades, reduce IT infrastructure management, and drive value with rapid implementation.even details of users who believed they deleted their accounts have been stolen again.“It’s clear that the organisation has failed to learn from its past mistakes and the result is 412 million victims that will be prime targets for blackmail, phishing attacks and other cyber fraud,” he added.The Adult Friend Finder data stretched back 20 years and included information such as usernames, emails, join dates and the date of a user’s last visit, according to Leaked Source.Passwords were also included in the trove — the vast majority of them featured unsecured protections or none at all, the report said.Last month a hacker known as Revolver or 1x0123 claimed he had gained access to the site’s backend servers through a Local File Inclusion hack before posting two screenshots purporting to show compromised data to his Twitter feed.The latest breach follows a high profile hack in May 2015 that led to the leaking of 4 million records.
