Mifare Classic emulation / sim

Hello smile

I'm trying to make some Mifare classic emulation / sim with the latest PM firmware

When interacting with the reader on my PC / ACR89, no problem at all smile
But when interacting with the real access reader:

Is the fact that Reader is sending HALT command just after SELECT can make the PM3 to be disappointed?
If yes, any idea to help the simulator to react like a normal/china badge ?

Thank you in advance for ideas smile

Re: Mifare Classic emulation / sim

Did you do hf 14a sim or hf mf sim? I am currently working on improving the latter. See https://github.com/Proxmark/proxmark3/pull/419. Please try this and report the results.

I cannot remember to have seen a reported issue about snoop on github or in this forum. Did you ever mention it?

How good/bad is your antenna? Please run hw tune and post the results.

Re: Mifare Classic emulation / sim

Both sniff commands below needs a great antenna (voltage only?) and precision placement with the involved reader antenna and tag antenna.  Placements like:  [r] - [pm3] - [t]  OR  [r] - [t] - [pm3]

hf mf Snoop/sniff
hf 14a snoop/sniff


My experience is that its never the same. Trial and error until you get a good sniff output.  For me I tend to keep the pm3 antenna very close to the tag antenna,  since that is the weakest signal I need to sniff and a bigger distance to the reader.

Re: Mifare Classic emulation / sim

Thank you guys, and sorry for the delay.

Just compiled from tonight with piwi code inside... simulation start, but without any success against this real reader (still OK on the PC one).
Will make more tests with differents placements from iceman's suggestions.

Re: Mifare Classic emulation / sim

Please tell us if you are using hf mf sim or hf 14a sim.

For further analysis please provide traces from both sim and snoop against the problematic reader.

And don't edit the output.

Re: Mifare Classic emulation / sim

Hey smile

I do a "hf mf sim" (after a "hf mf eload ..." of my backup)
=> "hf 14a sim" only simulate a UID for a Mifare Classic, no data inside, isn't it ? (I also tested after a "hf mf eload ..." of my data without success)

"hf mf sniff" does not seems to record any data... maybe I don't use it in the good way :s

Re: Mifare Classic emulation / sim

Your hf 14a snoop still doesn't show tag answers. This is probably the reason for hf mf sniff showing nothing useful. Still room for improvement with your antenna.

However I can see from your snoop trace that the time between the tag's answer and the next reader command is quite short. Probably too short for the simulator. Looks like we need to speed up the simulation even more...

Re: Mifare Classic emulation / sim

Ok guys, I made other tests with the FOB and snoop / sniff.
Both are now working smile

The distance between the card/fob and the reader is VERY important.
As a FOB can be smaller than the antenna, it was very important to let a small distance between reader and FOB roll.

But as I've presented in first message, it was "another problem". Any idea on the "too slow" simulation?
