, because default number of probes for a key recovery for one sector is 20. whole cracking cocould take from 30 minutes to 30 hours. You can also use the-K key parameter, to add a key to the list of known keys, which is being tried against your card in the initial phase. the-K option somehow didn't work for me, so I always compile my known keys directly into mfoc. c search for "array with default Mifare classic keys" not sure about other countries, but in country where I live keys are the sa

Two days ago, I saw an article about RFID security in TSRC. RFIDAttack Simulation1Card data sniffingThe so-called "sniffing" mentioned in this article is analyzed based on the context analysis (whether the reader can be read successfully depends on the communication distance of the RF card) and the original video of the author. The success condition of such a method depends only on the distance, and there is no other encryption mechanism. This is just a UID read. The title of the author is "card

audit and monitoring mechanisms, there is a big difference with the blacklist mechanism of the bank card system: The bus card uses an offline blacklist, and the capacity is limited by terminal devices, it is also a lagging processing (generally effective and the processing cycle is not less than t + 1 day); bank cards are blacklisted online, and the capacity is basically unlimited, and it is a real-time processing (immediate effectiveness and processing ). 3. Possible Mifare card system attack

, which would require a second device--proxmark, worth $300, simple operation and low cost.Tech Insider says: "Redteam Security has revealed to us a well-known problem with RFID or radio frequency identification, and is also the most commonly used method for many enterprise certified employees to access devices. Employees verify their identities through the RFID badge and gain access to a door. However, the problem is that in many cases, the
