Master ASPack, and you master the foundation of software unpacking.
Right at the entry point of an ASPack-compressed file, you will almost always see a PUSHAD (or equivalent architecture-specific) instruction. This instruction pushes all general-purpose registers onto the stack to save the CPU state before the unpacking stub executes. Step 4: Use the Hardware Breakpoint Trick Execute the single PUSHAD instruction (Step Into / F7). Look at the Stack pointer (ESP register).
