Malvertising chains and compromised websites are targeting US users with tech support scams hosted on numeric domain names. The goal of this scheme is to redirect users to domains consisting entirely of numeric digits like 6473819564947657419 and 7598437654236982[dot]win The domains look strange, but in reality they behave like other websites. Users who end up on the scammy numeric domains ultimately make contact with a browser locker. Users should install an ad-blocker, update their software on a regular basis, and configure their browsers to disallow automatic redirects to other websites.”]
