Re: MAGIC ISO15693 tags

I suspect the magic iso15 is just magic,  ie uid changeable.

Re: MAGIC ISO15693 tags

The magic card i have is reacting to the commands of the privacy mode. e.g. sending random numbers for the xor generation of the password.

Thats why i think that these cards can handle the privacy mode.

Is there a way that someone could ask the manufactor?

Re: MAGIC ISO15693 tags

@Iceman: within your iso15_magic.lua script there iss an option "-a" for using it with the official repo. Therefor I copied the iso15_magic.lua script and the read15.lua lib from your Repo into the official Repo, because I couldn't find these in there.
After using the magic script my ISO15693 Magic Card has an UID of "00 00 00 00 00 00 00 00". It looks like that the last two commands of your script do not work in this constellation which should write the two half of the UID.
With your Repo it was not a problem at all to change the UID back to a correct value (if the position of the tag is correct towards the proxmark3, which is kind of a hassle.).

What needs to be done, do get the magic script working within the official Repo?

Regards,
Gambrius

Re: MAGIC ISO15693 tags

dunno really,  I haven't used that lua-script with offical repo for quite some time.
Its usage is outdated in RRG/Iceman repo since its been incorporated into the client.

Re: MAGIC ISO15693 tags

@iceman: thanks for your reply. Got the answer (from you) within the other post, that it is done by csetuid now, because of the overheating issue in the RDV4.

Re: MAGIC ISO15693 tags

almost correct, buggy code on Offical repo leads to unwanted behavior like not shutting off rf power field.  As I said, once Piwis code becomes stable, we have a look at what is reusable.  Offical repo has been slacking off in being stable the last years.

Re: MAGIC ISO15693 tags

The "magic" commands are just write block commands to blocks 0x3e, 0x3f, 0x38, 0x39. The latter two write the UID (and the tag responds like to any other write block command). The tag however doesn't answer on the first two write block commands and the UID can be changed without them. Any idea what their purpose is?

Re: MAGIC ISO15693 tags

@piwi:
Because I am away from home (from my hardware) right now i am not 100% sure, but i think one of the first two comands  is zeroing the uid. I had an incident where I ended up with a uid filled just with 00 and my script did not run the ...38 and ...39 comand.
You could give it a try.

Re: MAGIC ISO15693 tags

Hallo,
The magic cards I have tested so far (e.g. from RFx) are all iso15693 SLIX cards. Because SLIX is not supporting PRIVACY MODE at all, i am looking for SLIX2 or SLIX-L cards with changeable UIDs.

Does anyone know wether there are any other cards available?

Regards,
Gambrius
