Manipulating HID card numbers.

Hi Guys. I remember there being some kind of HID bruteforce script around.
Can one of you point me to that script?

All i really want to play with is changing the number on a tag to see of the next few numbers in sequence also work.

HID Prox TAG ID: 3709cb6331 (45464) - Format Len: 36bit - FC: 0 - Card: 0

So i would like to try  (45465) etc. (I assume they usually are in sequence? or are they random numbers, and I should not bother?)

I am not sure how to calculate these out, so any info would be great.

Thanks guys.

A

Re: Manipulating HID card numbers.

does your tag have 45464 printed on it?  the pm3 didn't fully recognize the format (thus the FC: 0 - Card: 0) so the 45464 may not be correct either.

I believe iceman and others had a bruteforce, but it was only the 26 bit format as I recall.

This is from a keyscan transmitter so no tag ids are printed on the fob.. I have noticed they always scan like that. but a clone works.

Re: Manipulating HID card numbers.

What other purpose does the fob serve? (What do the buttons do?)

Re: Manipulating HID card numbers.

I'd forgotten to add the Bruteforce in the commandtable,  but now its there in the fork.  No script and untested.
I'm pretty sure you figure it out and can provide some feedback on it.
