Annotation: This article presents a formal formulation of the problem of modifying executable code during execution based on morphing used in computer animation. In the course of the research, the need for developing a morphing method for software was substantiated, and the basic principles used in computer animation were adapted for the field of cybersecurity, and vectors for further research in this direction were determined. The results obtained during the adaptation should be used in the design and implementation of the morphing method for executable code

Keywords: cybersecurity, executable file protection, binary morphing, protection against ROP chains
