A detailed look at the O.MG cable, which masquerades as a regular USB but allows you to hack devices, run scripts, record keystrokes, and operate from a distance of up to a kilometer. Learn how it works and how to protect yourself.
We’ve all heard the saying, “appearances can be deceiving.” In the world of cybersecurity, that saying rings truer than ever before, especially when we’re talking about the O.MG cable. At first glance, it may look like an ordinary USB cable, but it’s actually a handcrafted USB cable with an advanced implant hidden inside. It’s designed to allow red teams to simulate attack scenarios from sophisticated adversaries. They’re also incredibly effective tools for training and education. In this series of blogs, we’ll delve into the world of the O.MG cable and explore its interesting features.
The O.MG cable is a seemingly ordinary USB charging and data cable with a hidden twist. Inside, it has a built-in implant that allows it to act as a malicious tool. This is what makes the O.MG cable stand out. Hidden from view inside the cable is a tiny piece of hardware that acts like a mini-computer. This built-in system allows the O.MG cable to perform its unique tasks.
The equipment contains:
Wi-Fi Module: Allows the cable to connect to wireless networks, providing remote connectivity and control.
Storage: A small amount of storage for storing malicious payloads, scripts, or other data.
Processor: A microcontroller for processing commands and executing tasks.
The O.MG cable runs on firmware programmed into the cable’s internal hardware. This firmware allows users (or attackers) to customize the cable’s behavior, load scripts, and more. Once the cable is connected to a target device, the system can execute pre-programmed payloads or scripts, allowing it to interact with the connected device in a variety of ways.
The main appeal of the O.MG cable is its ability to remain hidden. Ethical hackers can use it to demonstrate vulnerabilities in an organization’s physical security protocols and endpoint protection. It’s also a great tool for conducting cybersecurity training sessions to show employees how seemingly harmless threats can be. In the wrong hands, this cable can be used to install malware, extract data, or perform other malicious operations on a victim’s device.
To get an idea of its features and capabilities, here is a quick overview:
While it may seem a bit confusing right now, the following blogs will go into detail about the individual features and capabilities of the cable. You can watch Hak5’s YouTube video: O.MG Cable – The New Batch to get an idea of the features and capabilities.
As of this writing, O.MG Cable Tier is offered in two plans/tiers:
Basic
Elite
The Elite tier was released this year. Since the base kit was received before the Elite version was released, it will be used for demonstrations and throughout this blog series. Let’s take a look at what’s included in the kit.
Programmer O.MG
The primary purpose of the O.MG programmer is to activate and configure O.MG cables. These cables are often supplied “deactivated” according to regulations and must be activated before use.
Mine looks something like this:
The programmer usually comes with an easy-to-use web utility that runs in a browser on your computer. This utility simplifies the process of activating, configuring, and updating the firmware for the O.MG cable.
The programmer can also be used to repair the O.MG cable if you are unable to access it. It also allows users to update the cable firmware, ensuring that the latest features and patches are available.
The new programmer with USB A+C looks something like this:
One of the key features of the O.MG programmer is its versatility. It is designed to work with all O.MG devices, whether cables, adapters or plugs. This means you only need one programmer, no matter how many different O.MG products you have.
This powerful and innocent-looking cable is as simple as it gets:
When buying cables, you should pay attention to the port types.
The cable above is a USB-A to USB Micro (black).
I chose the USB Micro pass-through connector (black). If you plan to use it with Apple devices, you should choose the Lightning connector (white).
However, with the Elite kit, you can choose/customize the type of cable you want to purchase on their website.
If you want to think a little about port types:
Here’s a new generation of spyware disguised as regular cables. Wi-Fi monitoring, keyloggers, self-destruction, attack scripts – all fit in your pocket. In three videos, Hak5 demonstrates how the O.MG Elite, HIDX StealthLink, and new braided unmarked cables work, making them hard to detect but easy to use against anyone.

The O.MG cable is not just a tool for red teams. It is the embodiment of a modern cyber weapon that disguises itself as everyday life. Its main strength is stealth, and the main threat is the user’s trust in an ordinary cable. Thanks to its built-in Wi-Fi module, microcontroller and data storage, O.MG allows you to launch remote attacks, record keystrokes and even automatically delete itself after completing a mission.
It can become a powerful training tool in the hands of an ethical hacker, but in enemy hands it is a means of penetrating internal company networks through the banal habit of “taking a charger in the office”. Today, this cable is not just a gadget for enthusiasts, but a symbol of a new era of attacks, where every centimeter of physical access can cost the confidentiality of the entire organization.
In future parts of the blog, the author is preparing to analyze in detail the capabilities of the firmware, types of attacks and practical cases. If you are interested in the security of your infrastructure, do not miss the following posts.
