Malware is a security threat, and various means are adapted to detect and block them. In this paper, we demonstrate a method where malware can evade malware analysis. The method is based on single-step reverse execution of code using the self-debugging feature. We discuss how self-debugging code works and use that to derive reverse execution for any payload. Further, we demonstrate the feasibility of a detection evading malware through a real implementation that targets Linux x86-64 architecture for a reference implementation. The reference implementation produces one result when run in one direction and a different result when run in the reverse direction.

We propose a new audio signal encryption scheme based on the chaotic Hénon map. The scheme mainly comprises two phases: one is the preprocessing stage where the audio signal is transformed into a data by the lifting wavelet scheme and the other in which the transformed data is encrypted by chaotic data set and hyperbolic functions. Furthermore, we use dynamic keys and consider the key space size to be large enough to resist any kind of cryptographic attacks. A statistical investigation is also made to test the security and the efficiency of the proposed scheme.
