Abstract

A mechanism is provided for detecting malicious activity in a functional unit. For a current activity value associated with a functional unit, a determination is made as to whether a thermal level associated with the functional unit differs from a verified thermal level beyond a first predetermined threshold. Responsive to the thermal level associated with the functional unit differing from the verified thermal level beyond the first predetermined threshold, a determination is made as to whether there is a known profile of thread activity levels that substantially matches current thread activity levels. Responsive to identifying the known profile that substantially matches the current thread activity levels, thread activity levels are compared to the known profile of thread activity levels. Responsive to the thread activity levels differing from the known profile beyond a second predetermined threshold, an indication of suspected abnormal activity associated with the given functional unit is sent.
