Nyseafaring.xyz is a fake website that is disguised as a legitimate news outlet. The page specifically targets sports fans by saying “Get The Latest Sports Updates From Around The World.” A prompt at the top of the page appears asking users if they want the page to send them push notifications.
Originally, push notifications were created just for this reason – to provide users with the latest news, updates, offers, and other valuable information. Some individuals came up with a way to abuse this function, and instead of providing content, they act as middlemen between users and advertisers.
