ASPack is a veteran executable packer used to compress and protect Windows Win32 EXE files. While it helps developers reduce file sizes and prevent casual reverse engineering, it is also frequently used by malware authors to hide malicious code from antivirus scans. ASPack Unpacker

The original Entry Point (OEP) of the application is hidden. ASPack changes the file's Entry Point to point directly to the unpacking stub.

The unpacking stub decompresses the original program code into the computer's memory. The stub restores the original import tables. While it helps developers reduce file sizes and
