The kind of skeleton key you would see in a cartoon that opens any door is what I want. It has always been a dream of mine to be able to slip in and out without being noticed.

Time and keys change as well. Your front door might still use a metal key, but offices and industrial facilities are more likely to use some kind of wireless keycard, whether it's Near Field Communication, Radio Frequency Identification, or something else. What do you think a tappable skeleton key looks like?

What is it?

The ChameleonMini can be used to clone and read high-frequency cards. It is able to sniff and log RF data and can be used as an antenna. It seems like a credit card from a distance. If you want to conduct penetration tests on your own systems, you can use one of the many chameleon apps.

A reader and a chip.

If you have an employee key that you can use, it can be used to make a functional replica of the key that will get you in wherever you want.

There are a lot of versions of the device that started as an open-sourced project. The revision G is our favorite version. It comes in a variety of colors and is powered by a battery.

What can it do?

cloning the UID and storing the data for later can be accomplished with the help of the ChameleonMini. The most obvious use of card keys is to execute an attack on the reader. It can be used to sniff for keys and crack them, but you have to be close to the keys to do that.

If you really want to cover your bases, there are many cheap devices available online with that function.

How much of a threat is it?

RF signals are used in your security system. The Proxmark3 is the most popular device in this category and the ICopy-X is built on the Proxmark. It can be used in conjunction with those tools for a more efficient hack.

It's possible to clone amiibos.

Simple tools can be found on Amazon for less than $30. There are a lot of old legacy keycard systems out there that have not been updated to the latest technology. Sometimes a simple tool can be the most effective.

There is a lot of open-sourced support for the Proxmark3 thanks to contributors like the Iceman. A wide array of Mifare cards and codecs are supported by the card. It can be used to perform limited sniffing and logging.

Could I use it myself?

It depends on how useful you are. You can control the device on the go from your phone if you have an app for the Chameleon family of devices. On top of that, there are some fairly good online tutorials. One of the more accessible hacking devices for beginners is the Chameleon.

Unfortunately for my dream of a universal skeleton key, using the Chameleon is more involved than just waving it at a door and opening it. It takes a good amount of knowledge and strategy to be able to use it effectively. It's perfect for people trying to learn the ins and outs of security, so they can conduct their own penetration tests and find the flaws in their security systems.
