*SUPPORTED TAGS: pyramid, awid, fdx, jablotron, noralsy, presco, visa2000, 14a, hid

|
|
|
This script uses the proxmark3 implementations of simulation to bruteforce given ranges of id.
|
|
It uses both LF and HF simulations.

-- Author note
|
|
-- I wrote this as i was doing a PACS audit. This is far from complete, but is easily expandable.
|
|
-- The idea was based on proxbrute, but i needed more options, and support for different readers.
|
|
-- I dont know LUA, so I used Brian Redbeards lf_bulk_program.lua script as a starting point, sorry if its kludgy.
