Aspack Unpacker [repack] -

1. Load packed.exe → break at 0x00401000 (stub). 2. BP on `GetProcAddress` → run → hit. 3. Continue running until a `jmp eax` with eax pointing to 0x0045A2F0. 4. Go to 0x0045A2F0 → looks like standard VC++ prologue. 5. Set Scylla: OEP = 0x0005A2F0 (RVA). 6. IAT Autosearch → found 45 imports. 7. Dump + Fix → unpacked_fixed.exe runs successfully.
