In February 2015, an IP.Board forum about Xbox called Xbox-Scene was breached and more than 432,000 member accounts were compromised. Hackers stole IP addresses, passwords, email addresses and usernames.
Anyone who used the forum on or before the breach occurred in February 2015 should change their passwords immediately, if they haven’t already, and they should also change it on any other accounts that shared the same password as Xbox-Scene.
