SNOOP SNIF AND COPY RFID CARD ...WHATEVER PURPOSE, BANKING, PASSPORTS, BUT SPECIALY SECURITY DOORS

Emulate and sniff Legic Prime cards with Proxmark 3

 

we have to investigate our university system, which used the Legic Prime chip and is now changing to Legic Advant. So for our seminar we have to attack the old system which we succeed by writing valid values to the card. The next step would be to emulate "own" cards with the proxmark3 and it would be nice to sniff to the traces.
So first: Emulating: Proxmark has already a function: "hf legic sim" [phase drift [frame drift [req/resp drift]]] Start tag simulator (use after load or read)
Which we used after reading a valid card but it didn't worked. Maybe someone can help us with that.
Second: Sniff traffic: We'd like to sniff the traffic between card and reader. But proxmark has no function to sniff legic traffic. We can only sniff 14a traffic without annotations but that didn't worked neither.
 

 

 ou can use the "hf snoop" to sniff the traffic between reader and card. Use the latest source from GitHub, compile & flash your proxmark3.

Good morning everybody!!!! welcome back to war!!! Because I never tried to robb a bank, concerning that they might stuck me between security doors, by remote action...and then, you get the money, and they get you :) And the next topic is the vault trucks locks, the sliding chit and etc etc...I have a trick here, so when you get inside the bank, and you want to make sure they won't lock you inside the facility, for those who are ready for the security vault, and want to go in the midlea of the night, also very profit trick :) : " (using tape) a piece of rigid plastic on the outside of a door, in such a position that, when the door would be opened, the plastic would be pushed and fall in between the door and its enclosure. The door, closing automatically, would then be prevented to lock fully."
