If you prefer automated solutions, these tools are commonly used for ASPack:

When the packed file is running in memory, it is . An unpacker’s job is to intercept the process right after the stub has finished its work but before the original code executes, then dump the decompressed memory back to a new .exe file.

Because the unpacking logic never fundamentally changes, ASPack will remain for the foreseeable future. The POPAD / JMP pattern is like a fingerprint—it cannot be removed without breaking the packer.
