Trend Micro researchers found that “in 2017, cryptocurrency mining detections climbed from around 75,000 detections in the first half of the year to about 326,000 in the second half. Compared to the previous half year, the first half of 2018 saw a 141 percent increase in cryptocurrency mining detections.” That’s more than 787,000 detections of malicious cryptocurrency mining in the first half of the year, according to the report.
In addition, this year Trend Micro started detecting “only cryptocurrency miner families that have outright malicious behaviors. Despite this distinction, we still saw 47 new cryptocurrency miner malware families. This indicates that different groups, rather than just an invested few, are mobilizing to take advantage of stealthy means to mine cryptocurrency.”
