What is self-mutating malware?

Code that rewrites itself on infection or replication, dodging signatures via polymorphism (decryptor changes) or metamorphosis (full body rewrite).

How does metamorphic malware evade detection?

By altering code structure, registers, and flow while preserving behavior—no static patterns, fools sigs and some heuristics.

Yes, but it's assembly-heavy; tools like Veil exist for red teams, but stability's a beast—test ruthlessly or crash.

🧠 Engineering Culture

Malware doesn't just hide—it reinvents itself with every infection. Twenty years in, and antivirus is still chasing ghosts.
