I have been getting hundreds of spam emails weekly about DailyGadgetReviews' or Daily Gadget Reviews' Drone X Pro or Quadcopter. The spam emails have links to websites with ".icu" domain names, which are being abused by online scammers and cybercriminals.
One of the DailyGadgetReviews' ".ICU" Websites

radiozero.icu
Once on the DailyGadgetReviews website, you will be taken to trackmy212.website, which is a suspicious website where hundreds of the suspicious ".icu" websites redirect their visitors to, in order to make payment.
It appears that DailyGadgetReviews creates a new ".icu" website daily because, since the writing of this article, I have received 3 more spam emails with links to different ".icu" websites.
