Elsewhere, a separate report this week suggested roughly $1.1 billion worth of cryptocurrency was stolen in the first half of 2018.

Exchanges made up 27% of attacks this year, according to the reports. $530 million worth of cryptocurrency NEM were stolen from Japan-based exchange Coincheck in January. In December, South Korean cryptocurrency exchange Youbit lost 17% of its digital assets.
