摘要: It is a promising way to detect polymorphic shellcode using emulation method. However, previous emulation-based approaches are limited in their performance and resilience against evasions. A new enhanced detection approach proposed, including an automaton-based model of the dynamic behavior algorithm, criterion which derived from that ensures high accuracy. The algorithm also contains several optimization techniques, highly improving running evasion shellcode. We have implemented prototype system for our approach. advantages validated by experiments with real network data, samples generated available engines hand-crafted
