Patent attributes
There is disclosed in one example a computing apparatus, including: a processor; and logic encoded into one or more computer-readable mediums, the logic to instruct the processor to: capture first data from an intermediate data source across a first temporal interval; perform partial signal processing on the first data to classify the first temporal interval as either suspicious or not suspicious, wherein the first temporal interval is classified as suspicious if it is determined to potentially represent at least a portion of a cryptomining operation; classify second through N temporal intervals as either suspicious or not suspicious; based on the first through N temporal intervals, classify the apparatus as either operating a cryptomining function or not; and upon classifying the apparatus as operating a cryptomining function and determining that the cryptomining function is not authorized, take remedial action on the apparatus.
