Understanding how Polymorphic and Metamorphic malware evades detection to infect systems

Polymorphic and metamorphic malwares are sophisticated threats that continuously change to evade detection. Polymorphic malware uses dynamic encryption keys to change its features, while metamorphic malware rewrites its own code with each iteration. Techniques used include subroutine reordering, dead code insertion and register swapping. They can be detected using entry point algorithm and generic description technology for polymorphic malware, and tracking emulators and geometric detection for metamorphic malware. Strong account protection policies and robust security solutions are advised to prevent both malware types.
