It's way too easy to buy legal hacking gadgets online

As more of our devices become connected, we have a greater chance of becoming a victim of cybercrime. 

And to make matters worse, there's a number of tools readily available online that can help a hacker break into anything from your WiFi network to your car.

We rounded up eight gadgets that anyone can legally buy online that can be used for hacking. 

Here's what we found:

This pricey kit can be used to read and clone RFID tags, which can be used to break into office buildings.

The $430 Proxmark3 Kit lets users read and clone just about any RFID tag.

RFID stands for Radio Frequency Identification, and it's a chip found in many items like security badges. In the case of a security badge, the chip will emit radio waves when activated by a reader to allow you entry into your building.

RFID readers, such as the Proxmark3 Kit, work by reading those radio waves and then cloning that signal to unlock the door.

A 29-year-old hacker was able to break into a GM OnStar car by building a device that cost about $100.

Created by hacker Samy Kamkar, the gadget is composed of only a few key components, including a $40 Rasberry Pi computer and three radios, all of which can be bought online.

The user simply attaches the device somewhere on the targeted car. When the owner then opens the OnStar mobile app within WiFi range of the vehicle, the gadget will relay valuable information to the hacker that can be used to locate, unlock, and start the vehicle.

Kamkar also built this $30 gadget that can unlock many cars that have keyless entry.

The device, called the RollJam, takes advantage of a flaw in keyless cars. When you hit a button to unlock your car, it sends a unique access code that will never be used again to do so.

When the device is placed on the car, it intercepts and stores the code sent to unlock the car by the owner. It does this two times, allowing the driver to finally gain access the third time the code is sent.

But by intercepting and storing two access codes, the gadget can be used to unlock the car at a later date. You can learn more about the technology here.
