CatSniffer

CatSniffer (😼) is an original multiprotocol, and multiband board made for sniffing, communicating, and attacking IoT (Internet of Things) devices. It was designed as a highly portable USB stick that integrates the new chips TI CC1352, Semtech SX1262, and Microchip SAMD21E17.

This board is a swiss army knife for IoT security researchers, developers, and enthusiasts. The board can be used with different types of software including third-party sniffers such as SmartRF Packet Sniffer, Sniffle, zigbee2mqtt, Z-Stack-firmware, Ubiqua Protocol Analyzer, our custom firmware, or you can even write your own software for your specific needs.

CatSniffer can operate in 3 different frequencies:

• LoRa
• Sub 1 GHz
• 2.4 GHz

This work was inspired by our friend's work Michael Ossmann as a tribute to his outstanding job in Greatscott Gadgets, making devices like the YardStick, GreatFET, HackRF, and Ubertooth.

Protocols

• Thread
• Zigbee
• Bluetooth 5 Low Energy (BLE)
• IEEE 802.15.4g
• 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks)
• Sub 1GHz and patented systems
• LoRa/LoRaWAN

Features

• "The SimpleLink™ CC1352P1F3RGZ device is a multiprotocol and multi-band Sub-1 GHz and 2.4-GHz wireless microcontroller (MCU) supporting Thread, Zigbee®, Bluetooth® 5.2 Low Energy, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), MIOTY®, Wi-SUN®, proprietary systems".
• CatSniffer uses SAMD21E17 as a USB-UART bridge to communicate with the CC1352 chip; it's not necessary for a manual driver installation (exceptions could exist).
• Compatible OS: Windows and Linux.
• Auto program through the bootloader from TI CC (as long as it's not disabled in the code). No need for an external programmer, and it can be debugged with cJTAG through the default pin.
• Antenna SMA port for an Antenna of your choice.
• LEDs of general-purpose.
• Reset button for SAMD21 & CC1352, Boot of CC1352, and one more for general purpose.
