Another advantage of displaying these adverts on video and gaming sites is there’s a much greater chance a user will keep the site open for longer. That translates into more time to mine and more cryptocurrency for the cybercriminals.
Popular cryptocurrencies such as Bitcoin require dedicated hardware to make mining worthwhile, and therefore isn’t appropriate for this malvertising setup. Instead, ESET lists ZCash, Feathercoin, Litecoin, and Monero as the focus.
So far the countries targeted by these malicious adverts include Russia, Ukraine, Belarus, Kazakhstan, and Moldova, with Russia being the main target. The adverts seem likely to spread further afield and head west, though, due to the potential to tap millions more PCs and generate more cryptocurrency.
