| Challenge | Example | Failure of single-phase tools | |-----------|---------|-------------------------------| | Indirect jumps | jmp [eax*4 + table] | Static disassembly yields no target | | Opaque predicates | if (x*x != (x<<4) - 16) | Always true but not simplified | | Packed sections | UPX, VMProtect entry point | Entropy-based detection fails without emulation | | Self-modifying loops | Decrypt next block at runtime | Static analysis sees garbage bytes |
