Bombercat is a security tool that combines an RP2020 and an ESP32 MCUs

Aug 7, 2022 — by Giorgio Mendoza 510 views

The BomberCat board by ElectronicCats is a device powered by an RP2040 chip and a ESP32 microcontroller. According to the company, this security tool supports NFC technology and magnetic stripe technology. Moreover, the board was specially created to audit, read or emulate magnetic stripes and NFC cards. 

According to the product page, the RP2040 chip found on this board interfaces with a PN7150 which is a new generation NFC chip. The ESP32 module can be seen located in the back of the board. Wi-Fi and Bluetooth capabilities are enabled by the ESP32-WROOM-32 which according to its datasheet has a maximum frequency of 240MHz.

The company also mentioned that the ESP32 co-processor comes with WiFiNINA firmware to allow Wi-Fi connections to be used with HTTP or MQTT protocols to allow relay and spoofing attacks to be tested over far distances or via web servers.

The BomberCat board seems to have three capabilities: Card emulation mode, Read/Write mode and Magspoof mode.

Card emulation mode: (BomberCat behaves as a smart card or a tag): In this mode, BomberCat emulates an NFC tag. It does not initiate communication, it only responds to the NFC reader. A typical application of the card emulation mode is how people use NFC on their smartphones to replace several cards, badges, or tags at once (using the same smartphone for RFID access controls, contactless payments, etc.)

Read/Write (BomberCat behaves as an NFC reader/writer): In this mode, BomberCat communicates with a passive tag, an NFC smart card, or an NFC device operating in the card emulation mode. It can read or write to a tag (although reading is a more common use case because tags will often be write-protected). In this mode, BomberCat generates an RF field, while a tag or card only modulates it.

Magspoof (for magnetic stripes interaction): Magspoof mode can emulate magnetic stripes cards by emulating the electromagnetic pulses of this type of card.
