anti copy, Mifare Sector0 / block0 should be locked #38
Comments
I am not sure I understand what I'm reading... |
Enable / Disable FUID ? UID for slot.. I'm not sure either but that could be of the french way of expressing things. There seem to be a wish for FUID to be optional per slot. What I'm curious is what functionality FUID stands for? use once? magic? ... |
|
Hm, this firmware as it is shouldn't allow for uid (block0) re-writing. Aha, I see in the source code there is no limit for block0 writes. ok. Fair enough, I agree. |
Now I get it and I agree |
the reader must understand that writing block 0 is impossible, he must just read the chameleon. I do not know which command the reader sends to do the test or detect a tag copy. apparently, new readers are not blocked only in France, but also in other countries. see you |
French readers implemented a 'magic check' where they send 0x43 0x40 to weed out magic tags. |
By "magic", you mean Chinese backdoor command ? |
Correct.
Also - it seems that this behaviour has now been removed by default.
|
@iceman1001 to be closed I think. |
@ShinHub double check in code that block0 doesn't allow for Write commands... |
@iceman1001 you were right... I took quantum-x answer as clue of a previous patch. |
keep in mind for your patch, that the support-chinese-magic command macro defines, at compilation time, should allow for updating block0 etc.. |
I swear won't hurt any chinese. |
You do have a sense of humor. Excellent. |
Fix #38: block0 was always writable
Now, new reader, fuck the chameleon, with anti-copy tag system.....
Please implement enable / disable fuid uid...for slot..... if is possible, right. ???
Thank you iceman1001.
