Flipper Zero : Empower Your Security Journey with The Ultimate Portable Multitool for Cybersecurity, Ethical Hacking, Penetration Testing, IoT Security, and Electronics Prototyping.
Flipper Zero is a compact, multi-functional device designed for security testing and hardware exploration. It enables users to interact with a variety of access control systems and wireless communications by reading, copying, and emulating signals from technologies such as RFID, NFC, infrared, and sub-GHz radio frequencies.
Launched through a successful Kickstarter campaign in 2020, Flipper Zero gained popularity for its versatility and user-friendly design. The device features a monochrome LCD screen and a five-button directional pad for navigation. Notably, it includes a virtual pet dolphin that reacts to user interactions, adding an engaging element to its functionality.
Flipper Zero’s capabilities encompass a wide range of applications:
- RFID and NFC: It can read, store, and emulate low-frequency (125 kHz) and high-frequency (13.56 MHz) RFID and NFC cards, commonly used in access control and contactless payment systems.
- Infrared Transceiver: The device can capture and transmit infrared signals, allowing it to function as a universal remote for various electronics.
- Sub-GHz Radio: Flipper Zero is capable of interacting with devices operating on sub-GHz frequencies, such as garage door openers and IoT sensors, by analyzing and replicating their signals.
- GPIO Interface: It offers general-purpose input/output pins to connect with and control external hardware components, facilitating hardware debugging and development.
While Flipper Zero is a powerful tool for security professionals and enthusiasts to test and understand wireless systems, it’s essential to use it responsibly and ethically. Unauthorized use of its capabilities can lead to legal consequences.

Every pentester should consider having a Flipper Zero because it’s like a Swiss Army knife for testing physical and wireless security. Here’s why it’s a must-have:
🔧 1. Multi-Protocol Capabilities in One Device
- RFID/NFC: Test badge cloning and access control systems.
- Sub-GHz: Interact with garage doors, IoT devices, and older wireless protocols.
- Infrared: Clone remotes for TVs, AC units, etc.
- Bluetooth (via dev board): Sniff and test BLE devices.
🧪 2. Hardware Hacking on the Go
- Has GPIO pins to interact with other hardware — perfect for quick and dirty hardware interfacing, debugging, or logic analysis.
🧰 3. Portable & Discreet
- It’s small, pocket-friendly, and looks like a toy. Great for red teaming or physical engagements without drawing attention.
🚀 4. Community & Extensibility
- Tons of custom firmware and plugins (like RogueMaster) that add features like Wi-Fi attacks, BadUSB, signal jamming (for research!), etc.
👨💻 5. Saves Time
- Instead of lugging around multiple tools or building custom setups, you get plug-and-play convenience for many common wireless/hardware tests.
⚠️ Caveat: Always use it within the boundaries of your engagement rules and local laws — some functions can cross legal lines if misused.
A quick hit list of top pentest tasks you can do with a Flipper Zero — super handy during engagements or recon:
🔓 Access Control Testing
- Read/Clone RFID cards (125kHz like HID, EM4100)
- Read/Emulate NFC badges (13.56MHz — MIFARE, etc.)
- Test building badge systems for weak cloning protections
📡 Wireless Signal Attacks (Sub-GHz)
- Sniff, capture, and replay signals from:
- Garage doors
- Car key fobs (unsecured ones)
- Wireless doorbells
- Brute force rolling codes (with add-ons, for testing weak implementations)
🛰️ Infrared (IR) Testing
- Capture and replay IR remote commands
- Test TVs, AC units, and projectors for universal remote vulnerabilities
🔌 Hardware Interface Hacking
- Use GPIO pins to:
- Interface with UART, SPI, I2C
- Dump flash memory from dev boards or routers
- Trigger hardware-based exploits (like JTAG poking)
💻 BadUSB Emulation
- Emulate a keyboard (like Rubber Ducky)
- Deliver payloads/scripts upon plugging into a target PC
- Great for social engineering drops
📶 Wi-Fi/Bluetooth Attacks (with add-ons like Wi-Fi dev board)
- Scan Wi-Fi networks
- Launch deauth attacks
- Interact with BLE devices (test fitness trackers, locks)
🧠 Bonus Recon Tools
- Signal strength meter for RF hunting
- iButton read/emulate (used in some legacy systems)
- Custom firmware enables even more — like Doom, Flappy Bird (okay, maybe not a test… but cool)
