Manual unpacking gives the analyst full control and is highly reliable. It involves running the packed program inside a debugger, letting the packer do the hard work of decompressing the code, and capturing the file right before it executes the malicious payload.

When automated tools fail due to modified headers or anti-analysis tricks, manual unpacking is required. This process involves loading the protected file into a user-mode debugger (such as x64dbg or OllyDbg) to find the Original Entry Point manually.

ASPack stub code typically pushes all registers onto the stack (using a pushad instruction) at the very beginning of the decompression loop. Once decompression is complete, it restores those registers with a popad instruction, followed immediately by a jump to the Original Entry Point (OEP).
