However, for malware analysts, security researchers, and curious developers, analyzing an ASPack-protected file requires a process known as "unpacking." This article explores the nature of ASPack and the methodologies used to reverse it.
This is the most crucial concept. Once the stub finished decompressing the code, it jumps to the OEP—the location where the original, unpacked program begins its execution. Methods of Unpacking ASPack
Look for the characteristic "tail jump" (usually a JMP or PUSH/RET instruction) at the end of the unpacker stub.
In the dump window, select the first four bytes, right-click, and set a (Dword). Press F9 to run the program.
