RFID cards could turn into a global security mess after discovery of hardware backdoor | TechSpot
Security researchers at Quarkslab have discovered a backdoor in millions of RFID cards developed by Shanghai Fudan Microelectronics (FMSH). When properly exploited, this backdoor could be used...
These chips are compatible with the proprietary Mifare protocol developed by Philips spin-off NXP Semiconductors and are inherently "intrinsically broken," regardless of the card's brand. When properly exploited, this backdoor could be used to quickly clone contactless smart cards that regulate access to office buildings and hotel rooms worldwide. Customers should be aware that RFID cards based on FM11RF08 and FM11RF08S chips are also used outside the Chinese market, with numerous hotels in the US, Europe, and India employing this significantly insecure technology.
