Binwalk Utility Helps You Analyze and Reverse-Engineer Firmware Files

Binwalk is a “firmware analysis tool designed for analyzing, reverse engineering and extracting data contained in firmware images”. This tool written in python supports Linux, and somewhat Mac OS X, can scan firmware files for files signature, and can be useful for hacking firmware files, and finding hidden information. Let’s install binwalk first. It’s very easy in a Debian or Ubuntu machine, as you just have to download the package, and run a script for installation:

wget https://binwalk.googlecode.com/files/binwalk-1.2.2-1.tar.gz
tar xzvf binwalk-1.2.2-1.tar.gz
cd binwalk-1.2.2-1/src
sudo ./debian_quick_install.sh

wget https://binwalk.googlecode.com/files/binwalk-1.2.2-1.tar.gz

tar xzvf binwalk-1.2.2-1.tar.gz

cd binwalk-1.2.2-1/src

sudo ./debian_quick_install.sh

If you have another Linux ditributions, it’s just a little more complicated. You still need to download and extract the release package as above, but you’ll have to install the following package depending on the features your need: Minimal installation – python 2.6 or greater, and python-magic To generate entropy plot graphs – python-matplotlib For automated extraction: Packages – mtd-utils zlib1g-dev liblzma-dev gzip bzip2 tar unrar arj p7zip p7zip-full openjdk-6-jdk Build and install […]

$27 TP-LINK TL-MR10U is an Hackable OpenWRT Wi-Fi Router with a Power Bank

TP-Link WR703N is a cheap 802.11 b/g/n router (you can now get it for about $20) that can easily be hacked to run openWRT and for example, act as an home automation gateway, printer server and more. But if you need a battery powered router for your application, TP-Link TL-MR10U, based on similar hardware as TL-703WR, should be a better match as it comes with a 2600 mAh battery, and costs just about $27 on DealExtreme. Here are the specifications of the device: CPU – Atheros AR9331 CPU @ 400Mhz System Memory – 32MB RAM Storage – 4 MB Flash Connectivity: 10/100 Mbit Ethernet port 802.11 b/g/n 150Mbps 3G support via external USB dongle USB – USB 2.0 port + micro-USB port for power Misc – Serial port access Dimensions – 91mm x 43mm x 25.85mm（L x W x H） The device comes with a microUSB cable and a user’s […]

Developers Are Working on Chromecast Functionality From Any Android Apps via Any Android Devices

If you don’t just come back from (too long) holidays, you should know Google has released the Chromecast, a $35 HDMI TV Stick that uses a protocol called DIAL to let users stream online videos on the TV via your mobile device or mirror your Chrome browser on the TV. However, there are currently quite a few limitations. It can only be used with apps specifically designed for Chromecast (e.g. YouTube, Netflix,…), and Chromecast is the only available receiver, and can only be purchased in the US. Luckily these may not be an issue soon… Koushik Dutta (Kouch) has taken care of the first issue by modifying Cyanogenmod to allow any video or audio app to stream the media files via the TV, using Android notifications. Perfect. Moving to the second issue. If you don’t live in the US, you’re still stuck, and if you do live in the US, […]

Hacking MK908 mini PC for Serial Console Access

Thanks to Omegamoon (and this brother) we already have instructions to connect the UART pins on MK808 in order to access the serial console. He’s done it again with MK908 mini PC featuring Rockchip RK3188. Tx and Rx pads are located on the RAM chips side, and he has connected the green wire to Tx (Going to Rx on TTL debug board), and a yellow wire to Rx (Tx on debug TTL board). A ground pad is available on the other side of the board. Since I got a sample for review from Geekbuying, I decided to give a try myself. The pad are quite small, so this may require patience, but it’s perfectly feasible. I wanted to keep the device closed, so I passed the wires through the ventilation holes (enlarging them a bit with a precision screwdriver), put back the main heatsink on RK3188, and reassembled the enclosure. […]

Zyxel NSA310 / NSA320 Hackable Network Access Storages Run Debian Linux

Yesterday, we saw how to make a NAS enclosure for the Cubieboard, but DesertF0x commented “Better take a NSA-310 or NSA-320. It is easy to install Debian and it has Gigabit!”, and I decided to have a look. The 2 devices appear to have been released at the end of 2011, and are powered by a Marvell ARMv5 compatible processor. Many NAS are expensive kits, but NSA310 (1 bay) is currently available for $88.50 and NSA320 (2 bays) for $95.34 on Amazon, which is just a little cheaper than the DIY Cubieboard NAS solution (~100 USD). Price looks attractive, now let’s have a look at some technical details, and instructions to install Debian. Both NAS more or less share the same hardware specifications except for a few details: Processor – Marvell Kirkwood 88f6281 ARMV5-TE compliant processor @ 1.2 GHz (Hardware datasheet) System Memory – 256 MB (NAS310) or 512 MB […]

Design West Summit – 23-25 April 2013

Design West 2013, previously known as the Embedded Systems Confertence, will take place later this month, on 23-25 April to be exact, at San Jose McEnery Convention Center in San Jose, California, US. The event will be divided into 22 tracks dealing with software development, hardware design, operating systems, security and more: Android Certificate Program – Two-day hands-on embedded android workshop. Black Hat Summit – The Black Hat Embedded Security Summit will provide electronics professionals with essential information and tools, as well as a forum for the discussion and evaluation of the latest solutions for securing their embedded systems. Training courses will focus on topics such as Network Security, Incident Response, Web Application Security, and Exploit Development. Connectivity and Networking – The Connectivity and Networking track educates design engineers on wired and wireless communications, spanning need-to-know topics from essentials of USB device development to antenna and RF system design. Debugging […]

How to Access the Serial Console in MK808 mini PC

Omegamoon has done a pretty neat hack on MK808 Rockchip RK3066 mini PC to connect a Sparkfun USB to TLL board and access the serial console for bootloader and kernel debugging. The first thing he had to do was to open the device, remove the heatsink, and locate the Rx/Tx pads on the board. The Rx and Tx pins are accessible through pads, not via through holes, so it’s just a little more difficult to solder, but nothing too challenging. He and his brother also soldered another cable to the ground. Then they inserted a 6-pin header via the ventilation holes of the device, soldered the 3 wires to the header, and fix the latter to the casing. Finally, they just inserted the debug board in the pin header, connected the USB cable to their PC, and started minicom (or equivalent) to start accessing the serial console. I think that […]

Beaglebone: The Perfect Telemetry Platform? – ELCE 2012

Matt Ranostay, technical staff at Ranostay Industries, gives a presentation about a telemetry system based on Beaglebone at the Embedded Linux Conference Europe on November 5, 2012. Abstract: The author will discuss his ongoing and other team members efforts to develop hardware and software that reports sensor data to the community. This talk will be split into several parts a) types of useful sensors b) hardware design of Beaglebone capes c) and telemetry reports to Pachube/Cosm. Demonstrating that in the new world of cheap prototyping boards with I2C, GPIO, and SPI that anyone can setup a decent monitoring system for home security, automation, and weather reporting. There will be a live demo of prototype geiger counter + weather station. The audience targeted is the professional hobbyist who likes to hack on microcontrollers in their spare time. It will take little to medium knowledge of electrical engineering to follow this talk. […]
