Cybercrooks have also started creating copycat cryptomining services of their own, offering similar code, but with outright malicious intentions.

Recent research has found that the level of illicit cryptocurrency mining is closely aligned with the value of Monero. The research also found that the volume of illicit mining detected in the wild increased in line with the rising value of Monero. In addition to hacking larger operations with robust hardware, cryptojackers benefit from hacking devices on the network of a small business. Especially if security is lacking, the mining software can quickly spread undetected. It is the unauthorised use of someone’s computer or mobile device as a host to then exploit its resources to mine cryptocurrency for profit.
