Mifare Classic Card Recovery Tools Beta V0 1 Zip


Mifare Classic Card Recovery Tools Beta V0 1 Zip




Mifare Classic is a type of RFID chip that is widely used for various applications such as access control, public transportation, payment, and identification. However, Mifare Classic has a serious security flaw that allows its encryption keys to be cracked by using a technique called nested authentication. This means that anyone with a compatible NFC reader and some software tools can read and write data on Mifare Classic cards without knowing the original keys.

One of the software tools that can exploit this vulnerability is called Mifare Classic Card Recovery Tools Beta V0 1 Zip. This is a ZIP file that contains two Windows applications that work with the ACR122U NFC reader. The first application is called mfocGUI, which stands for Mifare Offline Cracking GUI. This application can perform a dictionary attack on Mifare Classic cards and recover the keys for all sectors. The second application is called Card Recovery Tool, which can write data to Mifare Classic cards using the recovered keys.


The ZIP file was uploaded to the internet by an anonymous user in 2018. It is not clear who created these applications or whether they are safe to use. There is no source code provided for either of these applications, so they may contain malware or other hidden functions. Therefore, users are advised to use these tools at their own risk and only on a fresh virtual machine that can be deleted later.


The ZIP file can be downloaded from [this link], but users have to go through a lot of ads, pop-ups, and fake virus alerts before they can get the actual file. Alternatively, users can download the ZIP file from [this mirror link], which does not have any ads or redirects.


How to use mfocGUI




mfocGUI is an application that can crack the keys of Mifare Classic cards using a dictionary attack. A dictionary attack is a method of breaking encryption by trying many possible keys until finding the correct one. mfocGUI uses a file called keys.txt as the dictionary, which contains a list of common or default keys for Mifare Classic cards. Users can edit this file and add more keys if they know them.


To use mfocGUI, users need to follow these steps:



  • Connect the ACR122U NFC reader to the computer and install the PC/SC drivers for it.



  • Run mfocGUI.exe and select the reader from the drop-down menu.



  • Place a Mifare Classic card on the reader and click on "Read data".



  • The application will try to authenticate with each sector using the keys from the dictionary file. If successful, it will display the data of each sector in hexadecimal format.



  • If some sectors cannot be authenticated with the dictionary keys, the application will try to crack them using nested authentication. This may take some time depending on the card and the reader.



  • When all sectors are authenticated, the application will display a message saying "Dumping done". Users can then save the data as a dump file by clicking on "Save data".




Note that mfocGUI can only crack Mifare Classic S50 1k and S70 4k cards that use the old version of the Crypto1 algorithm. It cannot crack Mifare Classic EV1 1k cards that use a fixed version of Crypto1 algorithm. Also, mfocGUI cannot write data to Mifare Classic cards, even if it has cracked their keys. For writing data, users need to use another application called Card Recovery Tool.


How to use Card Recovery Tool




Card Recovery Tool is an application that can write data to Mifare Classic cards using the keys obtained by mfocGUI or other methods. It can also format a card back to its factory state or write the manufacturer block (block 0) of special Mifare Classic cards.


To use Card Recovery Tool, users need to follow these steps:



  • Connect the ACR122U NFC reader to the computer and install the PC/SC drivers for it.



  • Run CardRecoveryTool.exe and select the reader from the drop-down menu.



  • Select one of the options from the radio buttons: "Write data to card", "Format card", or "Write manufacturer block".



  • If the option is "Write data to card", users need to select a dump file that contains the data and the keys for the card. This can be a file generated by mfocGUI or any other compatible format.



  • If the option is "Format card", users need to enter the key for sector 0, which is usually FFFFFFFFFFFF. This will erase all data and keys from the card and restore it to its default state.



  • If the option is "Write manufacturer block", users need to enter the data for block 0 in hexadecimal format. This can be used to change the UID or other parameters of special Mifare Classic cards that allow writing to block 0.



  • Place a Mifare Classic card on the reader and click on "Start".



  • The application will try to write the data to the card using the keys provided. If successful, it will display a message saying "Operation completed".




Note that Card Recovery Tool can only write data to Mifare Classic cards that have writable sectors. Some cards may have read-only sectors that cannot be changed. Also, Card Recovery Tool cannot crack the keys of Mifare Classic cards, even if it can write data to them. For cracking keys, users need to use another application called mfocGUI.


Conclusion




Mifare Classic Card Recovery Tools Beta V0 1 Zip is a ZIP file that contains two Windows applications that can exploit the security flaw of Mifare Classic cards. These applications are mfocGUI and Card Recovery Tool, which can crack and write data to Mifare Classic cards using the ACR122U NFC reader. However, these applications are not official or verified, and they may contain malware or other hidden functions. Therefore, users should use these tools at their own risk and only on a fresh virtual machine that can be deleted later.


Mifare Classic Card Recovery Tools Beta V0 1 Zip can be downloaded from [this link] or [this mirror link]. Users also need to have the PC/SC drivers for the ACR122U NFC reader installed on their computer. To use these tools, users need to have some basic knowledge of Mifare Classic technology and hexadecimal number system. Users should also be aware of the legal and ethical implications of cracking and cloning RFID cards.
