In today’s fast-paced tech world, many organizations face the challenge of working with firmware that has been intentionally obfuscated or secured to prevent reverse engineering. Whether for security audits, vulnerability assessments, or system optimization, understanding and modifying such firmware is a critical step in gaining full control of embedded systems. At Circuit Engineering CO.,LTD, we specialize in helping clients disassemble and reverse-engineer these complex, secured firmware binaries to provide clear, usable C/C++ source code.

The Challenge of Obfuscated Firmware

Obfuscated firmware is designed to hide its underlying logic and make reverse engineering difficult. Many manufacturers intentionally encrypt, compress, or scramble the binary/heximal firmware to prevent competitors or malicious actors from accessing proprietary code or identifying vulnerabilities. The result is a binary that is hard to read, understand, or modify.

However, despite these challenges, disassembling obfuscated firmware is crucial for various applications, including bug fixing, custom modifications, security patching, and gaining deeper insight into the system’s functioning. This is where we come in.

firmware-ul obscurcat este conceput pentru a-și ascunde logica de bază și pentru a face dificilă ingineria inversă. Mulți producători criptează, comprimă sau amestecă în mod intenționat firmware-ul binar/heximal pentru a împiedica concurenții sau actorii rău intenționați să acceseze codul proprietar sau să identifice vulnerabilități. Rezultatul este un binar greu de citit, înțeles sau modificat.
Cu toate acestea, în ciuda acestor provocări, dezasamblarea firmware-ului obscurcat este crucială pentru diverse aplicații, inclusiv remedierea erorilor, modificările personalizate, corecțiile de securitate și obținerea unei cunoștințe mai profunde asupra funcționării sistemului. Aici intrăm noi.

Our Approach: Disassembling to Assembly Language and Decompiling to C/C++ Code

Our team of experts uses advanced techniques to disassemble the binary/heximal firmware into assembly language, the low-level programming code that the hardware executes directly. This is the foundational step in understanding how the firmware interacts with the hardware.

Once the firmware is in assembly language, we leverage powerful decompilation tools and custom scripts to reverse-engineer the assembly code into higher-level C/C++ source code. This source code is far more human-readable and modifiable, providing our clients with the ability to make necessary changes, improvements, or security patches.

Unser Expertenteam verwendet fortschrittliche Techniken, um die binäre/hexadezimale Firmware in Assemblersprache zu zerlegen, den Low-Level-Programmiercode, den die Hardware direkt ausführt. Dies ist der grundlegende Schritt zum Verständnis der Interaktion zwischen Firmware und Hardware.
Sobald die Firmware in Assemblersprache vorliegt, nutzen wir leistungsstarke Dekompilierungstools und benutzerdefinierte Skripte, um den Assemblercode in höherstufigen C/C++-Quellcode zurückzuentwickeln. Dieser Quellcode ist für Menschen weitaus besser lesbar und veränderbar und bietet unseren Kunden die Möglichkeit, notwendige Änderungen, Verbesserungen oder Sicherheitspatches vorzunehmen.

Understanding the Challenge

Obfuscation of binary or hexadecimal firmware is a common practice to protect proprietary code and prevent tampering or unauthorized modifications. This results in a compiled firmware that is hard to understand, with valuable logic often buried in complex, encrypted, or fragmented code. When clients encounter these challenges, they face difficulty in conducting vital tasks such as debugging, security assessments, or simply understanding the inner workings of a device.

Obfuzarea firmware-ului binar sau hexazecimal este o practică comună pentru a proteja codul proprietar și pentru a preveni manipularea sau modificările neautorizate. Acest lucru are ca rezultat un firmware compilat greu de înțeles, cu o logică valoroasă adesea îngropată în cod complex, criptat sau fragmentat. Când clienții se confruntă cu aceste provocări, se confruntă cu dificultăți în a efectua sarcini vitale, cum ar fi depanarea, evaluările de securitate sau pur și simplu înțelegerea funcționării interioare a unui dispozitiv.

Our service focuses on the process of disassembling obfuscated binary/hexadecimal firmware into assembly language, providing a deeper understanding of the firmware’s structure, logic, and functionality. By doing so, we restore the original logic of the embedded system, making it accessible and understandable for further analysis and improvement.

Unser Service konzentriert sich auf den Prozess der Zerlegung verschleierter binärer/hexadezimaler Firmware in Assemblersprache und ermöglicht so ein tieferes Verständnis der Struktur, Logik und Funktionalität der Firmware. Auf diese Weise stellen wir die ursprüngliche Logik des eingebetteten Systems wieder her und machen es für weitere Analysen und Verbesserungen zugänglich und verständlich.

How We Help

Our team of experienced engineers employs cutting-edge reverse engineering techniques to meticulously disassemble the compiled firmware. The process involves several key steps:

Firmware Analysis: We begin by analyzing the compiled hexadecimal or binary file to identify the obfuscation techniques applied, including encryption, packing, and fragmentation.

Deobfuscation and Decompression: Using specialized tools and proprietary methods, we deobfuscate and decompress the firmware to reveal its underlying structure.

Disassembly to Assembly: After successfully deobfuscating the binary, we disassemble it into assembly language, which is easier to interpret and modify.

Logic Restoration: Finally, we restore the original logic, functions, and routines, allowing you to understand the exact behavior of the embedded system.

Analiza firmware: Începem prin a analiza fișierul hexazecimal sau binar compilat pentru a identifica tehnicile de ofuscare aplicate, inclusiv criptarea, împachetarea și fragmentarea.
Deofuscare și decompresie: Folosind instrumente specializate și metode proprietare, deobfucăm și decomprimăm firmware-ul pentru a dezvălui structura de bază.
Dezasamblare la asamblare: după dezfundarea cu succes a binarului, îl dezasamblam în limbaj de asamblare, care este mai ușor de interpretat și modificat.
Restaurare logică: În cele din urmă, restaurăm logica, funcțiile și rutinele originale, permițându-vă să înțelegeți comportamentul exact al sistemului încorporat.
