Abstract
Software testing of networked devices using whitebox fuzzing is provided. Target network device (TC) can execute a software target that can selectively receive fuzzed data to perturb the execution of the software target. The perturbation can be correlated with the fuzzed data to detect intentional and unintentional features of the software target in. Information related to the interaction of the TC and a target network peer device (TPC) can be employed to determine a state input. Optionally, the TC can interact with the TPC normally until a determined state input, at which point, a fuzzed input can be substituted into the communication to the TC as if it were from the TPC. Resulting deviations from normal operation can then be determined and analyzed. Further optionally, a session dependent conditional and corresponding value can be determined.
