gaylord M FOCker - ready to pwn your MIFARE tags
Hello everyone and a happy new year (well, aparently you can see how long it took me to finish this masterpiece :) ).
This time we will low dive a little into the world of RFID and NFC.
Did you ever want to scare the shit out of your customer in regards to the security of his door locking system?
Do you think it is cool to open gates with a Flipper Zero?
You like yourself some close combat Red Teaming?
Get your Flipper Zero and Proxmarks ready and follow along, as we cover some basics and carry out a variety of attacks.
As this is absolute uncharted territory for me, this will (like almost always) be very beginner friendly.
Introduction
I was always keen to know about the inner workings of all those door closing / access systems that I ran across in mostly all of my pentests. You know, the ones that you also have like in hotels, for train rides etc., where you get a creditcard look-a-like and can access certain areas with it, or pay in your canteen.
But where to start? Ofcourse I asked Iceman, because when you only enter stuff like Proxmark, RFID hacking, Chameleon mini, there will be no way around him. He pointet me to his Discord, after reaching out.
But there is a catch: I don’t feel comfy with Discord. Always a pain in the ass, because everything is so fast. Searching stuff is a pitty, and everything is full of noise. I tried to find answers to:
- Where should I start?
- What hardware is sufficient for a beginner?
- and so on …
But guess what - either nothing or so much it wouldn’t help.
So back to some old school google-fu and try & error, and blog about it.
This was also a good justification to buy myself a Flipper Zero, because you know I needed it for my research :)
Additionally, the NFC Magic Flipper can also be used to automate various actions on the user's smartphone. By assigning specific actions to the device, such as opening a particular app or adjusting settings, users can simply tap the Magic Flipper to instantly perform these actions. This saves time and effort, making daily tasks more efficient and streamlined.
Terminology And Technical Background
First things first. What are we talking about in general?
RFID
RFID is an abreviation for R adio F requency Id entifikation.
It’s a technology that uses electromagnetic fields to transmit data that a receiver catches from an RFID tag. It is mostly one-way: tag -> reader .
The reader is also refered to as interrogator.
A tag at least consists of a chip or circuit and an antenna. There are active, passive and semi-passive tags, where the active version has it’s own powersource (so this adds to the components), the passive one is completely powered by the reader and the semi-passive one has a powered chip or circuit, but data transmission is powered by the reader.
Tags can be read-only or read-writeable.
RFID can operate on a variety of frequencies, like low-frequency (LF), high-frequency (HF), ultra-high-frequency (UHF), microwave etc., ranging from 120 kHz upto 24,125 GHz. For further info see here.
The used frequency as well as the type of tag play a role when it comes to the range a tag can be read from. We are talking about 10 cm - 200 m.
Usecases are inventory management, asset / personal tracking like ID tags in animals, etc.
NFC
NFC stands for N ear F ield C ommunication.
It’s a transmission standard derived from RFID, so also based on electromagnetic induction.
Unlike RFID communication happens bi-directional: tag reader .
NFC uses the HF of RFID, which is 13,56 MHz, and as such is limited to a very close range of operation of about 10 cm max.
We are again dealing with passive and active tags. Think of your smartphone or credit card.
Usecases are wireless payment, door locking systems, student IDs, transportation, etc.
MIFARE World
MIFARE is a contacless chipcard technology developed by NXP Semiconductors and residing inside the NFC cosmos. The evolution of the tags somehow looks like this, where each step introduced new (security) features:
- MIFARE Classic 1k & 4k (EV1)
- MIFARE Ultralight (no security, more cost effective cheap tag)
- MIFARE DESFire
- MIFARE Plus
The tag’s data is stored in blocks, and these are aggregated to sectors.
For a MIFARE Classic 1K tag this looks like this:
Sector 0 block 0 always holds the UID of the tag.
The last block of each sector stores the access keys A and B , as well as the access bits for this specific sector.
Both keys can be tied to different access rights, like read-only or write. To carry out certain actions on these blocks you need to know the “password” in terms of the key(s).
Pic thankfully stolen from here
Sectors can be assigned to applications, so that you could e.g. store data for multiple access systems on one tag. The information about which application is assigned to what sector is stored in the so called M IFARE A pplication D irectory, see here.
Hardware
I personally started just with the Flipper Zero. It could read tags, emulate them (turns out not completely) and attack them with wordlists. But I ran into the situation that I was not able to get all keys with the attacks available from the Flipper (or where is simply failed the attacks), and it also lacks support (as of now) to be used with nfc-tools or pm3.
So I also bought myself a Proxmark3 easy, to carry out some more attacks.
Getting started
Furthermore, the NFC Magic Flipper can also be used to enhance security measures. It can be programmed to act as a digital key, allowing users to securely access their devices or specific applications. By requiring a physical touch with the Magic Flipper, it adds an extra layer of protection and ensures that only authorized users can gain access. Overall, the NFC Magic Flipper is an innovative and practical device that makes use of NFC technology to provide a convenient and versatile user experience. Its compact size and ease of use make it a valuable tool for a variety of applications, from file sharing to security measures. As NFC technology continues to evolve and become more widespread, devices like the NFC Magic Flipper will become even more integral in simplifying our everyday lives..
Reviews for "Transforming the Retail Experience with NFC Magic Flipper"
1. John - Rating: 1 star
I was really disappointed with the Nfc magic flipper. The app constantly crashed on my phone and it was really frustrating. The flipper itself did not work as advertised and I couldn't get it to connect with my devices. The design also felt cheap and flimsy. Overall, it was a waste of money and I do not recommend it.
2. Sarah - Rating: 2 stars
I had high hopes for the Nfc magic flipper, but it ended up being quite mediocre. The app was difficult to navigate and the instructions were not clear. I struggled to set it up and when I finally did, the flipper did not consistently perform the desired actions. The range of the NFC signal was also disappointing, making it impractical for daily use. I do not think it is worth the price.
3. Michael - Rating: 1 star
The Nfc magic flipper was a complete letdown. It worked for a short period of time and then suddenly stopped. I reached out to customer support, but they were unresponsive. The lack of durability and poor customer service were major drawbacks for me. I regret purchasing it and recommend looking for alternative NFC products in the market.
