Researchers have been at work creating an AI algorithm to detect malicious cryptocurrency miners while avoiding legitimate ones. The detection method compares currently running miners to graphs of both legitimate and illegitimate miners and monitors changes between the processes being used and the scheduling of mining activity. This type of detection may be put to use to decrease the overall use of malicious code that can often tax the system’s CPU usage to max capacity.
