Polymorphic Malware
TL;DR
Viruses that change their code with each infection, evading signature detection.
Viruses that change their code with each infection, evading signature detection. Each copy looks different, rendering signature databases obsolete. Drove the shift from pattern matching to behavior-based detection.
Business Application of Polymorphic Malware
Polymorphic malware exemplifies how attackers evolve to evade defenses, forcing defenders to shift from recognizing specific patterns to detecting suspicious behaviors - analogous to competitors disguising their strategies.
