HydraTool first public version v0.3.1.0 is now released with source code under GPLv3
This PC tool use Qt5.x GUI and is available with pre-built exe for Windows & GNU/Linux

The actual Hydratool GUI has a main window mainly related to HydraBus+HydraNFC extension in order to display in real-time HydraNFC sniffed data for more details see https://github.com/hydrabus/hydrafw/wiki/HydraFW-HYDRANFC-guide#sniffer-iso14443a-with-unique-hard-real-time-infinite-trace-mode

The second window (when we click on Terminal icon) is mainly a basic Terminal in order to communicate with HydraBus firmware hydrafw but can be used with any Serial Port …

We are pleased to announce Free HydraBus Talk & Workshop RMLL 2017 4&5July

About the Talk 4 July 2017 14h00 (40mins):
This talk will focus on the hardware and mainly embedded open source firmware(hydrafw) / user commands features to be used by any guys interested in embedded hardware hacking from beginner to experienced hacker
For more details on this Talk see https://prog2017.rmll.info/programme/securite-entre-transparence-et-opacite/hydrabus-diminuer-le-ticket-d-entree-a-la-chasse-aux-bug-dans-l-iot?lang=en

About the Workshop 5 July 2017 14h00 (max 3h):
The workshop is the continuation of the talk “Hydrabus : Lowering the entry fee to the IoT bugfest” where the attendance will be able to try by themselves practical examples of physical attacks on small challenges.
For more details on this Workshop see https://prog2017.rmll.info/programme/securite-entre-transparence-et-opacite/atelier-hydrabus-sur-iot?lang=en


Thanks to our official re-seller https://lab401.com as now we have some nice video for HydraBus & HydraNFC products:


HydraBus Team RHME2 challenges write-up released for all challenges(22)
see https://github.com/hydrabus/rhme-2016


HydraBus Team have participated to Riscure, RHME2 and we are 1st !!
Thanks to all participants and Riscure for those amazing challenges


HydraBus boards are now back in stock (with same price as before) and new features:

  • New PCB v1.0 Rev1.2+ (add capacitor for MicroSD +3V3 for even more stable supply for big microSD/SDIO …)
  • Replaced MCU STM32F405 by STM32F415 with hardware cryptographic acceleration for:
    • AES 128, 192, 256
    • Triple DES
    • HASH (MD5, SHA-1), and HMAC
  • Added Clear laser-cut acrylic case with screws

HydraESP32 HydraBus v1.0 Shield for ESP-WROOM-32 V1.1 Rev1.0 is alive







This new version allow to measure ESP32 power consumption (and/or manage power ON/OFF of ESP32 with any MCU…)
This version can be fully managed using HydraBus STM32 MCU
For more details (BOM, Eagle board …) see
OSHPark link: https://oshpark.com/projects/dgKJqznH
GitHub link: https://github.com/bvernoux/hydraESP32


This 1st part is mainly how to connect  FTDI C232HM DDHSL-0 to ESP32 DevKitC (also called ESP32-CoreBoard V2)














For more details on JTAG /GDB /ESP32 OpenOCD see https://esp-idf.readthedocs.io/en/latest/api-guides/jtag-debugging/index.html


HydraBus Shield / Breakout board for ESP-WROOM-32 new version 1.1(rev1.0)







This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.

  • New features versus previous version V1.0 Rev1.1:
    • Added LDO (TPS73633DBVR SOT23-5) to convert 5V(VUSB) to a clean VCC (+3.3v) for ESP32 and which can be enabled by an HydraBus Pin or with a JUMPER on J7 (which connect +3.3V from HydraBus to EN of the LDO)
    • Added VCC connector in order to measure ESP32 current/power consumption (if not used to measure current just add a JUMPER on VCC to power the ESP32)
    • Added J6 connector to have access to ESP32 SPI FLASH IOs (now all pins are available)
  • This shield can be used only on bottom of HydraBus board (in order to use other shields on top of HydraBus)
  • The HydraBus board is a small (60mm x 37mm) and low cost, multi-tool extensible board with STM32F405 Cortex M4F 32bits MCU @168MHz with a fully open source firmware hydrafw and full online documentation hydrafw wiki
  • The ESP-WROOM-32 is a low-power 32-bit 240 MHz dual core MCU Wi- Fi+BLE combo module that highly integrates TCP/IP network stacks, 12- bit ADC and HSPI/SDIO/UART/PWM/I2C/I2S interfaces. See ESP32 Overview, ESP-WROOM-32 link/info, Espressif Products Overview including ESP-WROOM-32 PDF
  • Design based on official esp_wroom_32_datasheet_en.pdf (August 8, 2016)
