Old openraid.org accounts have been compromised

I just got the following alert from my identity theft monitoring today:In December 2016, openraid.org had 457.070 exposed records including usernames, emails and passwords. Originally hacked in 2015, the data remained out of sight until being offered for sale on a dark market site 1 year later.If you had a password on openraid that was shared with any other site, you might want to change your passwords.EDIT: Lots of questions about how the info was found/where it is; sorry, they did not provide that information to me, probably in the interest of not promoting darknet identity theft sites.
