identifying, by one or more computer processors, a plurality of seed candidates from a plurality of sets of random numbers generated at a computer, wherein each of the sets includes a plurality of random numbers; identifying, by one or more computer processors, a plurality of candidate performance counter frequencies from the plurality of seed candidates and from timing information associated with the sets of random numbers; and determining, by one or more computer processors, whether any of the candidate performance counter frequencies is consistent with a predefined virtual machine performance counter frequency. |
