Claim 15:
16. A computer implemented method comprising:
generating a hook on an application programming interface (API);
receiving, in response to a set of software instructions calling the API, an indication from the generated hook;
based on the received indication, accessing a call stack associated with an execution of the set of software instructions, the call stack comprising a call stack frame;
generating a trust metric for an execution of the set of software instructions, wherein generating the trust metric for the execution of the set of software instructions comprises evaluating the call stack with a level-of-rigor determined based on an attempted action by the set of software instructions to generate an indication of a potential threat, the trust metric based on the indication of the potential threat determined from evaluating the call stack frame;
determining, based on an evaluation of the generated trust metric, that the set of software instructions poses a threat to computer security; and
based on determining that the set of software instructions poses the threat to computer security, performing a corrective action.
