Unleash the Power of Your Cardputer: The Ultimate Guide to Evil-M5Project

Evil cardputer

In the world of pocket-sized pentesting, the M5Stack Cardputer has quickly become a fan favorite. But if you want to move beyond basic functions and turn your device into a powerhouse for ethical hacking and network exploration, there is one firmware that stands above the rest: the Evil-M5Project.

Developed by 7h30th3r0n3, this open-source project transforms the M5Stack ecosystem into a versatile toolkit for security researchers.

What is Evil-M5Project?

The Evil-M5Project is an innovative security firmware designed specifically for M5Stack devices like the Cardputer, Core2, Fire, and AtomS3. It serves as a Swiss Army knife for WiFi and Bluetooth analysis, combining features from famous tools like WiFi Marauder and Evil Portal into a single, cohesive interface.

Note: This project is designed for educational purposes, aiding in understanding network security and vulnerabilities in a controlled environment.

Key Features for the Cardputer

The Cardputer version of Evil-M5 (v1.4.9+) is particularly powerful because it leverages the device's full QWERTY keyboard and screen. Standout features include:

1. WiFi Pentesting & Analysis

  • Network Scanning & Cloning: Identify nearby networks and replicate them for authorized security testing.
  • Deauther & Auto-Deauther: Test network reconnection security (requires specific hardware/bypass).
  • Evil-Twin & Captive Portals: Set up rogue access points to demonstrate how phishing attacks work.
  • Beacon Spam: Flood the airwaves with fake SSIDs to test network congestion handling.

2. Advanced Wardriving

By adding a GPS module, your Cardputer becomes a Wardriving Master. It links captured SSIDs to geographic coordinates, generating CSV files compatible with Wigle.net.

3. Offensive & Utility Tools

  • BadUSB: Execute keystroke injection attacks via the USB interface.
  • Mouse Jiggler: Keep a target computer awake during forensic operations.
  • Skimmer Detector: Scan for Bluetooth signals associated with credit card skimmers.
  • LLM Chat: Integrate AI capabilities directly into your portable setup.

How to Install Evil-M5Project

The easiest way to get started is via the M5Burner tool:

  1. Download M5Burner: Get it from the M5Stack Download Center.
  2. Prepare the SD Card: Create a folder named evil at the root of your FAT32 SD card. Download and place the SD-Card-File contents from the GitHub repository into that folder.
  3. Flash the Firmware: Connect your Cardputer to your PC, search for "Evil-M5" in M5Burner, and click Burn.
  4. Boot Up: Insert the SD card into your Cardputer and power it on!

Why Ethical Hacking Matters

The Evil-M5Project is built for educational purposes. By using these tools, you can learn how to defend your own networks against common attacks. Always remember: never use these tools on networks or devices you do not own.

Conclusion

The Evil-M5Project turns a $30 hobbyist computer into a professional-grade security tool. If you're looking to explore the invisible world of radio waves and network packets, this is the project to follow.

The M5Stack Cardputer: A Genuine Flipper Killer for Under $30?

Cardputer ADV
If you’ve been hanging around the ethical hacking community lately, you’ve definitely seen the Flipper Zero. It’s sleek, it’s famous, and it’s also nearly $200. But while the internet was obsessing over the plastic dolphin, M5Stack quietly dropped a device that arguably packs more punch for a fraction of the cost: the Cardputer.

Whether you’re looking at the classic Cardputer v1.1 or the beastly new Cardputer ADV, this isn't just a toy—it's a pocket-sized pentesting powerhouse.

What is the Cardputer?

At its core, the Cardputer is a card-sized micro controller platform powered by the ESP32-S3 chip. Unlike the Flipper, which uses a more restricted architecture, the Cardputer gives you a dual-core processor, full Wi-Fi, and Bluetooth (BLE) capabilities natively.

It features a full 56-key keyboard, a 1.14" LCD, a microSD slot, and a built-in speaker/mic. It’s essentially a tiny Linux-capable (or at least MicroPython-friendly) terminal that fits in your wallet.

Why It’s a "Flipper Killer"

The "Flipper Killer" label isn't just hype. In the world of ethical hacking, flexibility is king. Here is how the Cardputer stacks up:

  • Price Point: You can pick up a Cardputer for around $30. You could buy six of these for the price of one Flipper Zero.

  • The Power of ESP32-S3: The S3 chip is a favorite for development. It handles modern Wi-Fi attacks like deauths and evil portals much better than the Flipper’s optional (and expensive) Wi-Fi dev board.

  • Expansion & GPIO: The Cardputer is built for the "maker" mindset. With its GPIO pins and Grove ports, you can snap on sensors, GPS modules, or even LoRa hats for long-range communication.

  • The Keyboard: Typing commands or passwords on a Flipper is a nightmare of scrolling through a wheel. The Cardputer’s physical keyboard makes it a legitimate on-the-go hacking tool for terminal work and scripting.

Cardputer v1.1 vs. Cardputer ADV

If you’re shopping for one now, you’ll see two main versions.

The Cardputer v1.1 is the reliable workhorse most people start with. However, the Cardputer ADV (Advanced) is where things get serious. The ADV version adds an expansion bus that allows for "Caps"—modular add-ons like the LoRa + GPS cap. This turns the device into a dedicated wardriving machine, mapping out Wi-Fi networks across entire neighborhoods while you just walk around with it in your pocket.

Advanced Pentesting Features

What can you actually do with it? Once you flash the right firmware (like Bruce, ESP32 Marauder, or the Evil-M5Project), the possibilities explode:

  1. Wardriving: Connect a GPS module and log every Wi-Fi network you pass.

  2. BadUSB / HID Attacks: Emulate a keyboard to inject payloads into a target machine.

  3. Signal Sniffing: With the right expansion, you can sniff sub-GHz signals, though the Flipper still holds a slight edge in "out-of-the-box" RF support.

  4. TV-B-Gone: Use the built-in IR emitter to take over screens in public spaces.

Verdict: Is it for you?

If you want a polished, "it just works" gadget, get a Flipper. But if you actually want to learn ethical hacking and development, the Cardputer is superior. It forces you to understand the code, the GPIO interactions, and the hardware limits.

It’s affordable, it’s incredibly powerful, and it’s arguably the most fun you can have with an ESP32-S3 today.
