"1" is mode to a 1k card,
"2 A" is we need find key for block 2 and that it is a A key

Tag isn't vulnerable to Nested Attack (random numbers are not predictable).But I got a negative result using the nested method and then I started using the hardnested method

Re: Proxmark3 (edit and copy mf classic 1k tag)
you are trying to run a command that doesn't exist in offical repo.
Try hf mf chk instead

Re: Proxmark3 (edit and copy mf classic 1k tag)
Hello, iceman!
I have previously run command - hf mf chk * ?
I found one key, then I found all the other keys using the hardnested method
How can I now dump the original tag and copy it to another new tag (make a copy of the tag)?

Re: Proxmark3 (edit and copy mf classic 1k tag)
I think there is a autopwn script in RRG repo, which can generate a key file which then can be used to dump a card. In general, the RRG repo the better choice für cloners.
