FriendFinder Networks Inc.
The organisation that runs AdultFriendFinder and additional pornographic websites suffered a hack; 412 million accounts were compromised.
The inadequate security procedures of the organisation allowed for the cracking of almost all account passwords. In the hack, deleted accounts were also discovered.
It was discovered that an attacker remotely might execute malicious code on the target web server by taking advantage of the AdultFriendFinder website's vulnerability.
Email addresses, usernames, passwords, site membership information, the IP address most recently used to log in, and the date of the most recent visit are among the stolen data, according to a review of the databases on the three biggest websites.
