According to the December report of McAfee Labs, for the year the growth of malware for hidden mining was 4467%. The experts also drew attention to the popularity of attacks aimed at mining on IoT devices.
In 2018, hidden mining became one of the key dangers in cyberspace. Only in the third quarter, the McAfee Labs team discovered about four million threats from miner viruses. In 2016 and 2017, the number of such threats did not exceed 500 thousand.
According to McAfee Labs, a vulnerability called CVE-2018-14847 infected more than 3,700 MikroTik routers in America and Brazil.
We would not usually think of using routers or IoT devices such as IP cameras or videorecorders as cryptominers because their CPUs are not as powerful as those in desktop and laptop computers. However, due to the lack of proper security controls, cybercriminals can benefit from volume over CPU speed. If they can control thousands of devices that mine for a long time, they can still make money.

In addition, McAfee Labs has discovered a new miner for Mac OS called OSX.Dummy. It is distributed through instant messaging chats and is hidden in the form of a program designed to solve "crypto problems".
