Evading network anomaly detection systems: formal reasoning …

WebThe proposed polymorphic blending attacks can be viewed as a subclass of the mimicry attacks. We take a systematic approach to the problem and formally describe the algorithms and steps required to carry out such attacks. We not only show that such attacks are feasible but also analyze the hardness of evasion under different circumstances. Webb. The profile of the payload generated by the polymorphic decryptor . c.
