Construction of Countably Infinite Programs That Evade Malware/Non-Malware Classification for Any Given Formal System
Published 2025-03-01“…Cohen gave a simple but realistic formal definition of the characteristic actions of a computer virus as a Turing Machine that replicates itself and proved that detecting this behaviour, in general, is an undecidable problem. In this paper, we complement Cohen’s approach by providing a simple generalization of his definition of a computer virus so as to model any type of malware behaviour and showing that the malware/non-malware classification problem is, again, undecidable. …”
