Unsupervised detection of anomalous processes using hardware features

摘要

Disclosed are devices, systems, apparatus, methods, products, media and other implementations, including a method that includes obtaining current hardware performance data, including hardware performance counter data, for a hardware device executing a first process associated with pre-recorded hardware performance data representative of the first process' normal behavior, and determining whether a malicious process is affecting performance of the first process based on a determination of an extent of deviation of the obtained current hardware performance data corresponding to the first process from the pre-recorded hardware performance data representative of the normal behavior of the first process.
