1. A method of analyzing behaviors in a mobile computing device connected to a peripheral device, comprising:

  • identifying a capability related to the peripheral device connected to the mobile computing device;

    determining a feature on the mobile computing device related to the identified capability;

    generating, via a processor of the mobile computing device, a classifier model based on the determined feature, wherein the classifier model includes decision stumps that evaluate features of the mobile computing device related to the peripheral device, wherein each decision stump is a one level decision tree that includes a single node and a weight value, wherein the single node tests a condition related to a mobile device feature that is present in the mobile computing device due to the connected peripheral device;

    observing, via the processor, mobile device behaviors related to the peripheral device to collect behavior information;

    generating, via the processor, a behavior vector for a configuration of the mobile computing device based on the collected behavior information;

    applying, via the processor, the generated behavior vector to the generated classifier model to generate a result;

    using, via the processor, the generated result to determine whether one of the observed behaviors is an undesirable behavior; and

    terminating the undesirable behavior on the mobile computing device in response to determining that one of the observed behaviors is an undesirable behavior.
