Note, for the nested attacks - if you don’t have a known key, these can be sniffed from the access control reader, and then cracked (MFKey32/64). Constructive collaboration and learning about exploits, industry standards, grey and white hat hacking, new hardware and software hacking technology, sharing ideas and suggestions for small business and personal security. As it says your card is not vulnerable to default nested attack and requires hard nested attack, which isn't implemented at this moment on CU.
