Use HackRF SDR to Lock / Unlock Car

CubicSDR - Lock / Unlock Intercept

I’ve previously covered getting your HackRF set up in Linux and getting the firmware updated. In that guide we installed the very easy to use CubicSDR application and were able to easily tune to various audio signals.

Today we’re going to do something more interactive and actually use the transmitter. We’re going to unlock and lock my vehicle using the HackRF! Let’s get started.

Read and Reset Car Codes – Wireless ODBII Diagnostic Tool

2006 Chrysler 300C ODB Port

Chances are if you own a vehicle at some point you’ve experienced a check engine light on your vehicle. When this happens it’s common to stop by an auto-parts store or the dealership to have them read the code and determine what is wrong. Most auto parts stores will have a little diagnostic computer they can plug in to read the code.

Today I wanted to highlight a really inexpensive way that you can interface with that same diagnostic computer yourself using a cheap (<$30) adapter that not only allows you to read these codes but to actually reset them!

I’ve found it very empowering to have one of these as I can immediately research any check engine codes my vehicle has and determine what I’m going to need to do to resolve it. It’s also great if you have a check engine light for something you already know about as you are able to reset them yourself. Let’s get started!

HackRF Software Defined Radio Guide for Linux

Cubic SDR - Main Screen

The term “software defined radio” simply means that parts of a radio that were traditionally hardware are implemented in software. This means that functions that used to require knobs, dials or some kind of physical mechanism can now be controlled via software. Essentially this makes using computers/ software with radios much easier and more accessible (cheaper) than it had ever been traditionally.

Now with that background I can explain what the HackRF device is. The HackRF is a software defined radio device that is designed to let you access *all* of the radio spectrum all the way from 1 MHz up to 6 GHz! Think of it like a FM radio where the frequency controls don’t stop at 88 MHz or 108 MHz and you could turn it way below or above that. That is exactly what a HackRF is!

You are definitely not limited to listening to radio stations though. You can basically receive all types of signals with the HackRF (depending on your antenna) including video and data signals which can be processed by your computer. In this guide I’m going to cover how to get started with a device like this in Ubuntu Linux and give you an idea of what kind of things you can do with it!

Pwnagotchi WiFi Audit Tool Build / Guide

Pwnagotchi Raspberry Pi Zero W Build

A “pwnagotchi” is a device used for wireless security auditing / hacking that captures the handshakes of any WiFi access points in range of the device. These handshakes can later be cracked. How difficult these are to crack depends on how secure the wireless network is. If the network is set up with the latest encryption standards and an extremely secure password (or is using WPA encryption) it can be nearly/essentially impossible. If the password is a common dictionary word it may crack within seconds.

It’s common and smart security practice for both enterprises and home users to check what kind of networks are operating within range. It’s common to find devices that are “broadcasting” a wireless access point used to share internet but this is often not intended / authorized. It’s also very common to find devices using extremely insecure passwords that will crack in seconds that are authorized to be on the network but need a more secure password. These are basically backdoors into your home / company and they can go for a long time without being caught when this is never checked for.

The “pwnagotchi” tool automates this process. It will capture anything in range to be easily checked later for extremely insecure hashes (typically using hashcat or there are even online tools to find common hashes which we will cover). This saves a ton of time and can greatly improve your security. Today I’ll cover how to build a pwnagotchi setup as well as the steps to use it. Let’s begin!

Using Multiple M.2 NGFF 2280 SATA Drives Simultaneously

IOCREST NGFF 2230/2242/2260/2280/22110 SATA PCIe Enclosure

I’ve been running pibenchmarks.com for several years now so I’ve held on to any spare storage devices I can get my hands on for benchmarking/testing/cataloging purposes. This led to a big surplus of drives and no easy way to utilize them. That was before getting some new tools to be able to utilize lots of drives at once.

Last time I covered a monster 16 bay hot swappable 2.5″ SATA cage (as well as a more reasonable 8 bay option) in this “extreme storage” series of articles and in this article we’re going to cover M.2 SATA NGFF / M.2 NVMe drives. It’s also possible to do RAID!

Monster 16 Bay Hot-Swappable 2.5″ SATA Cage – ICY DOCK

ICY DOCK 16 Bay SAS/SATA Backplane Cage

I have a *lot* of 2.5″ SATA drives around the house that have collected from over the years from various devices. Often these drives have useful data on them or aren’t big enough to justify using on their own. The absolutely monstrous ICY DOCK 16 bay 2.5″ SAS/SATA backplane cage solves all of these problems and lets you hot swap (change out the drives while the OS is running) drives live in your OS!

In this guide I’ll cover how what I needed to actually set up something like this and my advice for people who are interested in these same type of hot swappable / RAID capabilities. I’ll also share the “sweet spot” recommendation to get the most bays for the least money if you’re on a tight budget. Let’s get started!

Ubertooth One Kali Linux Latest Tools / Firmware Setup Guide

Kismet Ubertooth One BTLE Capture

The world is full of devices communicating with Bluetooth even if (or maybe especially if) you don’t realize it. Most “smart” devices are advertising some Bluetooth services (some of them even publicly writable without a password!). Even my treadmill is advertising writeable Bluetooth endpoints!

The Ubertooth One is a bluetooth and bluetooth low-energy (BTLE) capture device intended for developers and security researchers/auditors. It has an external antenna and is able to communicate at much further distances than most BTLE devices by both transmitting more powerfully and having a more sensitive antenna to listen to the response. To find out what is nearby and happening over the air this is the device you want to have.

In this guide I’ll show you how to get the latest Ubertooth tools on Kali Linux as well as update the firmware for the Ubertooth device and actually use the device!

Hardware Technician Tool Gems: Precision Electric Screwdriver

wowStick w/ included accessories

This is the second in a series of articles about tools I’ve found during my IT hardware technician career that made my life much easier. These are all tools I have used for years that a lot of people have likely never seen or been exposed to before. Last time we covered a replacement for canned air / duster and this time we’re going to cover the wowStick fully electric precision screwdriver!

If you’ve ever opened a laptop or cell phone you know there are dozens of screws you have to remove. One of the best purchases I’ve ever made was an electric screwdriver. Let’s take a look at why!

A Good Alternative to Canned Air / Duster for Electronics

OPOLAR Air Duster for Electronics / Computers

As a computer technician / technology enthusiast I have a lot of electronics that need to be kept clean. I used to use canned air / duster for this task but it’s pretty nasty stuff to work with. It is extremely cold, you don’t want to contact any coolant with any components, the bottles run out at the most inconvenient times and generate a bunch of waste, etc.

For this article I just wanted to share a tool I found a couple of years ago that made my life a lot easier. It is also cheaper over time and much more environmentally friendly!

Alternative to Wired – Ethernet Over Power

Ethernet Over Power Wall Rack

Ethernet over powerline tech has existed for a while but traditionally has frankly sucked. It was slow and had issues with reliability.

After decades of improving standards and technology this has changed dramatically and now makes a very cheap and attractive alternative to wireless in many situations. The latest iteration gives a 1200 Mbps connection right over your existing power lines in your house and is designed to work in “noisy” power environments without interruption.
