McAfee Laboratory's December 2018 Threat ReportPDFIn the first quarter of 2018, the security company stressed that the number of malware targeting miners of encrypted currency had increased significantly. This trend seems to have declined slightly in the second quarter, but in the third quarter, it grew by nearly 40% annually. McAfee noted a decline in the number of new blackmail software packages over the past few quarters. This indicates that these attackers are turning to a more profitable cryptojacking mode.
Due to the general lack of appropriate security control, devices such as Internet of Things devices such as IP cameras and routers are very vulnerable to attacks. Although these devices do not have a powerful CPU, a large number of them can still bring valuable returns to hackers. Overall, there has been a steady and predictable growth in malware over the past two years, and this trend shows no signs of slowing down.
