The Limits: Packing and Obfuscation
- Packers compress / encrypt the real payload; the file on disk is a small unpacking stub plus an opaque blob.
- Strings, imports, and code you see may be the packer's, not the malware's.
- Obfuscation: string encryption, control-flow flattening, API hashing, dead code, anti-disassembly tricks.
- Static alone can stall → combine with dynamic unpacking.
Key Takeaway
If strings and imports look "too clean," suspect packing. That absence is itself a signal.
