Many access control systems still rely just on the UID of the card. It is a unique number, generated during manufacturing, read-only and impossible to change. There are however special, unofficial “Magic UID” cards (like my business card) that allow to set any UID - clone it from other cards. It takes just a few seconds with the new “one click” cloning feature that I have contributed to free Mifare Classic Tool Android application.
During upcoming Confidence conference in Krakow, we will celebrate 15 years of SecuRing. On this occasion the we will share with you several NFC “research toolkits” hardware sets - that among other things allow to clone card UID and crack Mifare Classic. Come meet us at our booth and solve the NFC challenges to win one!
Also be sure to attend my introductory talk on NFC security “A 2018 practical guide to hacking RFID/NFC” track 1 Jun 4th 11:50am.
