#Running the nested attack using the known key: pm3 -> hf mf nested 1 0 A A0A1A2A3A4A5 d Testing known keys. However even in the worst scenario tested (32 fully random keys) it still takes only about 5 minutes to get all keys. This process is very quick in our case, since most of our keys are default and the nested script checks for them before doing any actual calculations. As such we use the nested attack, which uses a single valid key to discover the other 31 keys. With one key we’re not able to do much though, we need all 16 A/B keys to fully dump the card contents.
In our case its pointless since we already know almost all valid keys however if you want to test it out here’s the command: pm3 -> hf mf darkside This takes a few seconds (usually about 5). This attack aims to recover one key from the card.

The first attack on Mifare cards is called Darkside attack, which exploit the weak pseudo-random generator on the card to discover a single key. But leaving risk aside, lets see what attacks we can carry out using the Proxmark.

Mifare Classic cards have been cracked years ago, yet are still in widespread use all around the world and most integrators simply ignore this security risk.

This is where Proxmark starts to shine, since most of what we’ve done so far can be done with a simple Android App ( MIFARE Classic Tool). Sectors 2–15 are empty, meaning that all the crucial data that allows the user to enter the building is in Sector 1. After reading Sectors 2–15 using: pm3 -> hf mf rdsc Sector 0 is a read-only sector with the UID (a unique card ID number that normally is not changeable) and manufacturers data. Surprisingly, all sectors except for sector 1 use a default key.

After confirming they were Mifare Classic fobs (the most widespread 13.56MHz RFID chip) the first step was to simply try reading the card using default keys, that conveniently Proxmark already has built-in. The most obvious implementation of RFID were the key fobs used to enter my residential building.

Proxmark3 RDV4 Verification and testing for default keysĪfter installing all the software/drivers and flashing the Proxmark with the latest firmware ( GitHub), all of which was quite straightforward thanks to well documented installation guides it was time to choose my target.
