Hiew Tutorial: Hex Editing for Beginners

Hiew (short for Hacker’s View) remains a top hacker tool because it combines a lightning-fast, console-based UI with the rare capability to both disassemble and assemble binary code in real-time. Created by Eugene Suslikov in 1995, this classic hex editor has outlived countless GUI-based competitors. It stays indispensable for modern reverse engineers, malware analysts, and exploit developers who value raw, uninterrupted speed. 💻 Tri-Mode Viewing Architecture

Hiew allows users to cycle instantly between three fundamental perspectives using a single keystroke (F4):

Text Mode: For reading ASCII and Unicode string literals embedded in files.

Hex Mode: For viewing raw binary data, tracking offsets, and modifying raw data blocks.

Decode Mode: A built-in disassembler that translates raw bytes into readable x86, x86-64, and ARMv6 assembly instructions. 🛠️ Key Technical Features

In-Line Assembler: Unlike basic hex editors (like 010 Editor) that only allow you to overwrite hex pairs, Hiew lets you type assembly commands (e.g., MOV EAX, 1) directly into code. It handles the background conversion to machine code automatically.

Deep Executable Parsing: It natively parses structurally complex file formats including PE/PE32+ (Windows), ELF/ELF64 (Linux), and Mach-O (macOS). It exposes headers, section tables, and import/export lists automatically.

No File Size Limitations: It handles multi-gigabyte memory dumps or massive software binaries instantly without lagging or crashing.

Keyboard-Driven Ergonomics: The tool relies entirely on keyboard shortcuts and navigation commands. Analysts can find data, patch functions, and extract blocks without ever touching a mouse. 🎯 Why Hackers Still Choose Hiew Over Modern GUIs

While advanced tools like IDA Pro and Ghidra are preferred for broad software analysis, Hiew remains the dominant utility for “surgical” binary patching. If a security researcher needs to bypass a localized license check, neutralize an IsDebuggerPresent() anti-debugging call, or insert shellcode into a specific offset, loading an entire GUI suite is inefficient. Hiew can be opened in a command terminal, jumped to an offset, patched with standard assembly language, and saved in under 10 seconds.
