I have recently had odd things happen with the Nexus site, but I don't know if they are in any way related to the potential breach. When I open links to random mods and categories, it will redirect me to an ad site, (This last happened a few days ago and I honestly cannot remember what the site was). It was similar to Adfly, there was a bar at the top, something along the lines of "Wait X more seconds before you will be redirected" Each time, I closed the tab before it loaded fully, to avoid popups that won't allow you to close the window itself. It was weird, and not something that has ever happened to me (Before a few days ago) when on the Nexus. I've had MalwareBytes block potentially malicious stuff several times while on the site too, but that stopped a while ago. If that helps, great! If not, oh well. Either way, thanks for the heads up! Good luck getting to the bottom of the issue
