USAGE:
|
|
script run brutesim -r rfid_tag -f facility_code -b base_card_number -c count -t timeout -d direction
|
|
option argument description
|
|
------ -------- -----------
|
|
-r *see below RFID Tag: the RFID tag to emulate
|
|
-f 0-999 Facility Code: The facility code (dfx: country id, 14a: type)
|
|
-b 0-65535 Base Card Number: base card number to start from
|
|
-c 1-65536 Count: number of cards to try
|
|
-t .0-99999, pause Timeout: timeout between cards (use the word 'pause' to wait for user input)
|
|
-d up, down Direction: direction to move through card numbers
|
|
-h Show this
|
|
|
|
*SUPPORTED TAGS: pyramid, awid, fdx, jablotron, noralsy, presco, visa2000, 14a, hid
|
|
|
|
EXAMPLE:
|
|
script run brutesim -r pyramid -f 10 -b 1000 -c 10 -t 1 -d down
|
|
(the above example would bruteforce pyramid tags, starting at 10:1000, ending at 10:991, and waiting 1 second between each card)
