The original assembly code is mangled and rewritten into complex, mathematically equivalent instructions that confuse static analysis tools like IDA Pro or Ghidra.
Additionally, recent Enigma versions include :

Hook memory read/write operations to identify where the polymorphic stubs write decrypted code.
OEP is typically found in .text section (now unpacked). The unpacker validates by checking for standard PE prolog ( 55 8B EC or 64 A1 30 00 00 00 ).
The following resources provide the best "paper-like" technical depth on the subject: 1. Technical Unpacking Methodology (Tuts4You Research) The original assembly code is mangled and rewritten

This article explores the technical nuances of Enigma Protector 5.x, the challenges of unpacking it, and the latest trends regarding tools in the security analysis community. What is Enigma Protector 5x?
Enigma 5.x completely strips the original Import Address Table. It replaces standard API pointers with references to dynamically allocated memory blocks inside the protector's workspace. The unpacker validates by checking for standard PE
This article explores the technical landscape surrounding Enigma Protector version 5.x, the lifecycle of unpackers, and what the "UPD" (Update) designation truly means in this high-stakes game.
Enigma Protector 5.x introduced several next-generation features:
One of Enigma's strongest defenses is IAT destruction. In a normal PE file, the IAT contains pointers to Windows API functions required for the program to run. Enigma destroys the original IAT, replaces it with custom redirection stubs, and resolves APIs dynamically at runtime. It may also use API hooking or simulate API code directly inside its own memory space to prevent standard IAT reconstruction tools from mapping the functions. 3. Virtual Machine (VM) Architecture
