Per the report, after in-browser mining service CoinHive shut down in early March — when the team claimed that the project had become economically inviable — cryptojacking against consumers has sharply decreased.

Cryptojacking is the use of a computing device for mining cryptocurrency without the knowledge of the device’s owner.
