The Secrets of SUBE NFC Card Hacking: What You Need to Know


How to Hack a SUBE NFC Card and Travel for Free in Argentina




SUBE is a contactless smart card used for public transportation in Argentina. It uses NFC (Near Field Communication) technology to communicate with the readers installed in buses, trains and subways. The card stores the balance and the transactions history in an encrypted form. However, some hackers have found ways to hack the SUBE NFC card and travel for free or even make money by selling cloned cards.

In this article, we will explain how to hack a SUBE NFC card using some tools and techniques. We will also discuss the risks and consequences of this illegal practice. Please note that this article is for educational purposes only and we do not encourage or condone any illegal or unethical activity.


What Do You Need to Hack a SUBE NFC Card?




To hack a SUBE NFC card, you will need the following tools and devices:


  • A smartphone with NFC capability. You can use any Android phone that has NFC enabled. You can check if your phone has NFC by going to Settings > Connected devices > Connection preferences > NFC.



  • An app that can read and write NFC tags. There are many apps available on Google Play Store that can do this, such as NFC Tools, MIFARE Classic Tool, or NXP TagWriter.



  • A Proxmark3 device. This is a powerful tool that can read and write RFID and NFC tags. It can also clone and emulate cards, crack keys, and perform other advanced functions. You can buy a Proxmark3 online from various sources, such as AliExpress, eBay, or Amazon.



  • A computer with a USB port. You will need a computer to connect your Proxmark3 device and run some commands. You can use any operating system, such as Windows, Linux, or Mac OS.



  • A SUBE NFC card. You will need a valid SUBE card that has some balance on it. You can buy one from any authorized point of sale or recharge it online.



How to Hack a SUBE NFC Card Using Your Smartphone?




One of the easiest ways to hack a SUBE NFC card is using your smartphone and an app that can read and write NFC tags. Here are the steps to do it:


  • Download and install an app that can read and write NFC tags on your smartphone. For example, you can use NFC Tools.



  • Open the app and tap on Read. Then, place your SUBE card on the back of your phone near the NFC antenna. The app will scan the card and show you some information about it, such as the UID (Unique Identifier), the type of card (MIFARE Classic 1K), and the sectors and blocks of data.



  • Tap on Write and select Write dump (MIFARE). Then, choose a file name and location to save the dump of your card. This will create a backup of your card data on your phone.



  • Now, you can edit the dump file using any text editor on your phone or computer. You can change some values in the file, such as the balance or the timestamp of the last transaction. However, you need to be careful not to change anything else that may corrupt the file or make it invalid.



  • After editing the file, you can write it back to your card using the same app. Tap on Write and select Write dump (MIFARE). Then, choose the file that you edited and place your card on your phone again. The app will overwrite the data on your card with the modified data.



  • Congratulations! You have successfully hacked your SUBE card using your smartphone. You can now use it to travel for free or with a lower fare until it gets blocked by the system.



How to Hack a SUBE NFC Card Using Your Proxmark3?




Another way to hack a SUBE NFC card is using your Proxmark3 device and some commands on your computer. This method is more advanced and powerful than using your smartphone, but also more complicated and risky. Here are the steps to do it:


  • Connect your Proxmark3 device to your computer using a USB cable. Make sure you have installed the drivers and software for your device before doing this.



  • Open a terminal or command prompt window on your computer and navigate to the folder where you have installed your Proxmark3 software.



  • Type "proxmark3 comX" where X is the port number of your device. For example, if your device is connected to COM3 port, type "proxmark3 com3". This will launch the Proxmark3 client software.



  • Type "hf search" to identify if your card is a high frequency (NFC) card or not. If it is, you will see some information about it, such as the UID, the type of card (MIFARE Classic 1K), and the keys for each sector.



  • Type "hf mf dump" to dump all the data from your card to a file called dumpdata.bin on your computer. This will create a backup of your card data on your computer.



  • Now, you can edit the dump file using any hex editor on your computer. You can change some values in the file, such as the balance or the timestamp of the last transaction. However, you need to be careful not to change anything else that may corrupt the file or make it invalid.



  • After editing the file, you can write it back to your card using your Proxmark3 device. Type "hf mf restore" to restore all the data from dumpdata.bin file to your card. This will overwrite the data on your card with the modified data.



  • Congratulations! You have successfully hacked your SUBE card using your Proxmark3 device. You can now use it to travel for free or with a lower fare until it gets blocked by the system.



What are the Risks and Consequences of Hacking a SUBE NFC Card?




Hacking a SUBE NFC card may seem like an easy and tempting way to save money on public transportation in Argentina, but it also comes with some risks and consequences that you should be aware of before doing it:


  • Hacking a SUBE NFC card is illegal and unethical. You are breaking the law and violating the terms and conditions of use of the service. You are also stealing from other users who pay their fares honestly.



  • Hacking a SUBE NFC card is risky and unreliable. The system may detect that you are using a hacked or cloned card and block it automatically or manually at any time. You may lose all your balance or even get fined or arrested by the authorities.
