My Robot Has WiFi!

Wireless communication using Bluetooth! Thanks to the Adafruit EZ-Link!  Basically that tiny board sticking out on top is a Bluetooth Serial-Link, allows me to remove the cable that binds the robot to my PC / MAC.  Now I cannot only program the robot wirelessly, but if I choose to, I can send it commands wirelessly over the air – thus completing Asimov’s second rule of robotics (if you don’t know the…

It Can See; Giving Your Bot Sight!

Previously we unveiled our love for the Arduino and the Zumo Shield that gives us a massive head start to building our own robot army.  The basic shield has a Zumo reflectance sensor array for primarily line following, and an LSM303DLHC accelerometer & magnometer (magnet-o-meter) for navigation.  But a lot of the remaining Arduino pins are not used, so this gives us the capability to add more tech or sensors so our robot can…

Rise of the Machines: Arduino Bots

Robotics Week Its robotics week (April 5th – 13th) 2014 (http://www.nationalroboticsweek.org), on Arduino Day (29th March 2014) I posed the question “What will you Build?”.  Well here in the Pentura office, we went out and bought some Zumo Shields from Pololu.  The shields are also available from our favourite electronics provider Adafruit.  The shield is a quick an easy insertable arduino shield that slides perfectly into place on an Arduino Uno R3…

Proxmark3 vs Ultralight C

There have been no secrets this week while I’ve been trying to add Mifare Ultralight C support to the Proxmark. Ultralight C cards are HF (13.56MHz) tags that are part of the Mifare family.  This week has been an interesting learning process, and it has corrected some misconceptions I had about the card.  For those interested you can follow my progress at http://www.proxmark.org/forum/viewtopic.php?id=1946.  But I will summarise my findings below: Ultralight C…

RFID Wallets/Sleeves. How much Security do they provide?

With the increasing amount of RFID technology creeping into everyday life.  Just how much data can be obtained from your wallet?  At Pentura we undertook a small experiment where using standard off-the-shelf products, we would attempt to obtain personal information leaked from RFID enabled devices: UK Passport UK Bank Cards Debit/Credit Access Control Tokens Our experiment used standard unmodified off-the-shelf RFID equipment: 13.56MHz ACR-122U Reader Proxmark3 with LF antenna Proxmark3…

Ubertooth – Bluetooth Sniffing Updated for 2014!

Earlier I noticed this tweet on my twitter feed: Ubertooth release: https://t.co/cCYHNf34Yc I know it’s been a long time coming, I promise not to leave it so long next time. — Dominic Spill (@dominicgs) February 20, 2014 So I thought I would walk you through the update, which has improved Operating System support, improved Bluetooth Low Energy (BTLE) support, and GitHub integration to make community development easier….

Telephony Hacking and Fraud | Securing Telephony Systems

Telephony Fraud Telephony Hacking and Fraud is once again on the rise.  Phone Phreaking was common between the 60’s and 90’s; it allowed Phreakers to place free calls and access Remote Dial-In computers; from there they would add voicemail boxes, snoop on phone lines, add call forwarding etc. Phreaking once again is emerging with modern technology (VOIP, SIP, IAX etc).  Just like open web-services, that allow public internet users to…
