- NDEF data layout.
- size 144bytes.

Protection:
------------------------
PWD, PACK for reading tag data.
Tag data doesn't seem to be encrypted out of the box.  Maybe when it used in the game. to be verified.


Dump:

Re: [FINISHED] a popular toy Lego Dimensions

Iceman - Figured out my token recognition issue - I cant rest the tag on the antenna, I need to hold it slightly above to get a read, so I have looked at 5 Tokens - (4) in the Starter kit and (1) from an Level expansion. 

I have the UIDs, Auth Password, and PACK for each - The PACK is generic for all tokens read so far with a PACK of : AA 55

What else can I do to help out??

nice, if you can make a complete dump of all tokens it will help.

Re: [FINISHED] a popular toy Lego Dimensions

Already on it - I have a complete dump of the base (4) Figures and now all (3) from the Dr Who Level Pack.   Two from the DrWho pack wont ID in the game yet since you need to be at a point in the game to "activate" them, so they are either K9 or the Tardis and I wont know until I play that level smile 

The two new figured from the Dr Who pack also had PACK's of AA 55, so I think after 6 of them we can assume they all use that for the PACK.   I do have more to scan and I will this weekend, so Ill have (6) more to add to it, if they help.

I can zip them up and put them on sendspace.   Do you want any of the Capture information / etc included?   (I have a file, its messy, but has the information in it).   Ill add it to the ZIP just in case, you can delete it if you don't need it.

Ill do that after I catch up on my paying Job.......   So in a few hours Ill have it up there.

Those two tags are vehicle/blank tags so can be set as either. After you have played through the Dr Who level you can use him to program any vehicle tags into tardis/k9 or use Batman to make a bat mobile.

Re: [FINISHED] a popular toy Lego Dimensions

Cool - Makes sense, first time I ever saw that in the game (But it was my first level pack).   I also have the Simpsons and Back to the Future.   I'm hoping we can get some others to contribute some of the team packs / fun packs and Jurassic World Level pack.

Re: [FINISHED] a popular toy Lego Dimensions

You can email me the link or publish it here.  That decision is up to you.
My email is littered all over this forum.

And yes,  PACK is fixed.  The pwd gen is known. I have a lua script for it.

The data mapping process is been worked on by some talented ppl.  There is where your dumps will come in handy.

Re: [FINISHED] a popular toy Lego Dimensions

Oh wow ... Yeah, I must have just missed it - I was up way too late when I was fighting the dump issue I had until I started to change the distance from the tag to the antenna - and once that worked, I had to dump the tags - So I was tired....  Thanks for the link and sorry for the dump question.

Are there magic cards that can do NTAG213's?   Using the PM3 to sim sim is one way, but you often need more than one tag on the game at a time.   

What I found interesting (at least for me since I'm new to NFC hacking) once the original figure is authenticated, I used a UL tag emulator (doesn't support UL-C) with the token dump taking out all the empty memory addresses with all 00's so it would fit on the EMU and it would work great, but of course that's only due to the system not authenticating the token since it was authenticated once before.  Not sure if tats common or not?

Re: [FINISHED] a popular toy Lego Dimensions

the distance between reader and tag is a common fault to make.

I haven't heard of any magic NTAG213 tags. Use your google-foo and see if there is some out there.

I don't have the Lego setup, so I don't know too much about its behavior.

Re: [FINISHED] a popular toy Lego Dimensions

Yeah - that distance was a killer, Just annoying when I know it should work and I just try it figuring it my be noise / too strong and bam it read (That was 3 hours and frustration but all part of the experience....)

I appreciate the replies and education - Only been 2 days of playing and its a blast - needed something to toy with since I'm in a hotel suite for 2 months as we wait for house to get built.   I need to get marshmellows fork, I think that has the hf mfu sim command in it from reading.

Did some goole searches Tuesday for some emus, seems theres one that has 1Meg of ram and allows for multiple tags in a single space - Main thing I find is they mention UL-C's but never NTAG's - So Ill have to reach out to them to verify.  Too bad you cant make a classic 1k emulate NTAGs somehow...  have those around for Skylander playing around - I want to toy with Infinity as well, but I think you guys have that all figured out already?   I saw one post on it, but didn't see the full information anywhere in the forum...

Re: [FINISHED] a popular toy Lego Dimensions

@Marshmellows fork and seperate branch,  or mine fork has the same UL stuff.  wink

if you had a joop card maybe you could make it act like a ntag, but if there no market for it the chinese will not make it.
You can order a magic ntag if you want to pay up for it to be made.  There is some other threads for magic desfire/15693 tags.  Where the minimun order to create is 10000€ / 1000pieces or something like that.  I didn't hear more about it. The was a magic 15 tag on taobao,  i'm curios to buy it to see what it does and of course a magic iclass would be nice.

DI, well, yes,  there is some ppl who has all info,  same goes with Sky, amiboo etc etc. There enormously much done which isn't public since everyone doesn't want to get a cease and decease letter. If you get somewhere with your research may you get in touch with ppl.

Re: [FINISHED] a popular toy Lego Dimensions

belette - smile   Would a regular 213 tag work since you cant change the UID on it? 

Iceman - Good point on the market, and makes logical sense.   The classic magic cards had a big market, I cant see the NTAG (depending on which variant) having a huge market right now (Not a legit one at any rate).    For now Ill stick with the Lego to see what we can figure out - This one is more intriguing to me that sky and the others.    Totally understand the down low on this, I'm not a fan of the vendors losing money either, so a huge public release of most of this stuff isn't on my list either (One reason I asked about emailing you the tags rather than a public post).   

I thought I had your latest fork and the hf mfu eload wasn't in it, probably something on my side - Now that I had some sleep, I need to look over my environment some to make sure I'm setup correctly.

Awesome forum for knowledge, I thank you guys for all the answers / etc ...  If theres a chance to keep me in the loop on anything the dumps helped with, I would appreciate it.

Re: [FINISHED] a popular toy Lego Dimensions

if you figure out wether the data is encrypted and be able to decrypt it..  then you should be able to clone ..
if you figure out some of the data mapping, like where the toytype is stored, you might be able to not only clone but try all different toytokens on a empty ntag card...    many ifs but still...

I can get some 231 tags cheap to play around with ... Might just to see what I can / cant do....  I have all regular M1 Classic, or UL-C tags.... Nothing for NTAG's at all....  So Ill have to grab a few and some 215's just to have them to toy with.

Re: [FINISHED] a popular toy Lego Dimensions

I took the liberty of comparing sllabgib's dumped with mine. The writable tags do not have much secrets. Vehicle/Gadget IDs as well as Enhancements are static. The data has no CRC/signature. I've attached a screenshot for illustration. Unfortunately, the dynamic lock bits are set correctly. Hence, there is no chance of repurposing a vehicle/gadget tag for a figure tag.

Codes start at   ED03  through til FF 03 and  0004 to 65 04   . They are grouped in the 3 variants ee03 ef03 ff03 are the bat mobile and it's two rebuilds.

Re: [FINISHED] a popular toy Lego Dimensions

That's a lot of typing lol

Have you got any hints for the uid to pwd algorithm? I wanted to try abs work it out for myself, but haven't found a single link yet.

Re: [FINISHED] a popular toy Lego Dimensions

as far as the pwd-gen-algo the status is not so good.  lack of huge dataset of uid/pwd is missing to do proper analyse on.

Re: [FINISHED] a popular toy Lego Dimensions

It probably uses a pseudorandom generation algo; collectiong UIDs from ...00000, 00001, 00002, 00003 and correspective password is the only way to try to find it.

Re: [FINISHED] a popular toy Lego Dimensions

Hi,

I have made 16 dumps here with password for each tag.
What is the best way to share with you ? Something like sendspace ?

Re: [FINISHED] a popular toy Lego Dimensions

Sendspace is nice,  but dumps is not needed so much. 
If you make a list with  UID|PWD|PACK|TOKENNAME   and share it,  that would be good to have.

Re: [FINISHED] a popular toy Lego Dimensions

So, here it is :

UID|password|Pack|Name

CHARACTERS:

046050bcca704080|712810eb|aa55|batman

046a6e8832544281|04fc476d|aa55|chell
044bd4130a9a4081|219ee4cd|aa55|gandalf

VEHICLES:

04120f911a5c4985|a759dc0b|aa55|TARDIS
04c3da951a5c4980|de7a2f7b|aa55|K9
04ed00619a6d4084|97b7672e|aa55|HomerCar
0432ec52daa24081|a963d6ce|aa55|Batmobile
043c8e3e82b93f80|ddf1bf02|aa55|Taunt-o-Vision

044965a062a34080|0615215a|aa55|Delorean

PWD is generated from UID ?

What about NDEF data ?
I have "en9575748S2315" for Gandalf, but sllabgib have "en9537910R1115". This is perhaps used for password generation, no ?

Re: [FINISHED] a popular toy Lego Dimensions

The assumption is that the pwd is generated from UID.   If you sniff the communication between token and portal (good exercise)  you'll see it never reads no blocks before authenticating.

As mentioned earlier in this thread,  we would need to collect uid|pwd via simulation.  Some specific cases of uid is needed to start figuring it out.

Re: [FINISHED] a popular toy Lego Dimensions

Looking at the first pairs in your list and seeing such huge difference when changing one bit,  makes me thinking that they are using a CRC- or HASH- algo on the uid.  Or it may even be a crypto algo...

Assuming the portal has the pwd-gen-algo in its firmware (and not in game software),  and transaction speed is quite normal I would lean on CRC or Hash.

Re: [FINISHED] a popular toy Lego Dimensions

Great sim ! Can you start with 00000000000000 and not 0400000000000 ? Thank you for your support !
