Hello! New to it all, Proxmark3 RDV4.0 arrived today!

Hi guys,

I am human, can confirm beep boop beep...

New to RF and Proxmark and reading like crazy to try and wrap my head around this complex world. My Proxmark3 RDV4.0 arrived today, got the firmware and software installed successfully but yet to understand:

How to 'arm' the device for standalone emulating.

I tried to clone my work badge as a test but it's a HF Mifare DESFire 4k card...from what I gather these are hard to crack? Anyone know if it's possible? Code from searching card below:

 UID : 5f 1f f3 43
ATQA : 00 04
 SAK : 20 [1]
TYPE : NXP MIFARE DESFire 4k | DESFire EV1 2k/4k/8k | Plus 2k/4k SL3 | JCOP 31/41
 ATS : 0a 78 80 70 02 20 63 cb b7 80 8b 30
       -  TL : length is 10 bytes
       -  T0 : TA1 is present, TB1 is present, TC1 is present, FSCI is 8 (FSC = 256)
       - TA1 : different divisors are NOT supported, DR: [], DS: []
       - TB1 : SFGI = 0 (SFGT = (not needed) 0/fc), FWI = 7 (FWT = 524288/fc)
       - TC1 : NAD is NOT supported, CID is supported
       -  HB : 20 63 cb b7 80
No chinese magic backdoor command detected
PRNG data error: Wrong length: 0
Prng detection error.

Valid ISO14443A Tag Found - Quiting Search

I am going to be using this for Red Teaming.

welcome to the forum, you can repost qour question after you have full access...
just for now, your work badge does not seem to be a MF DESFire card, it's only one of the possible options listed by the proxmark ...
for reference: ATS of a MF desfire: 75 77 81 02 80
