Re: Advant Scan

Legic is not part of hf search. (well, since you are using Iceman's build I'm not certain of that...)

Use legic specific cmds if you know what it is.  (But the legic cmds are in early development still.)

Re: Advant Scan

Hi marshmellow,

I know about Legic prime being supported but Advant is the "new" legic technology, as opposed to prime which is working ok-ish in current proxmark (lack of proper protocol support-> bitbanging).
Advant is claimed to be ISO14a compliant ( and supposedly secure ! )

I'm still working on having mosci's lua working with my advant tags, all CRC are wrong smile

Re: Advant Scan

Proxmark can not read Leagic advant media. The one u got is a type of advant card based on a DESfire chip. This is special EAL4 certified card. It has nothing to do with the other advant chip types. They are not limited to ISO14441A, the are also support ISO15693 variants.
So in any way the legic LUA script will not work with advant media, since proxmark can not read any data from it.

Re: Advant Scan

Hi Jason,

May I ask you to contact me ? either on IRC or by email. Working on legic.lua ad I'm pretty sure you are one of the knowledgeable persons on this area.

Re: Advant Scan

well,  on iceman fork,  "hf legic reader" is connected with "hf search".. Nevertheless,  the whole Legic Advant documents etc is much sought after.

Re: Advant Scan

I have all documents available, the problem is the watermarking of this documents. Last year I started to remove it and encountered there are watermark fragments inside, so by knowing where the fragments are, someone could reassemble them easily (e.g. Legic).
So I stopped there and thought about createing a thread with advant specifications... but the massive amount of data is really hard work to be written by hand... than I was very busy also, so I dropped that at this point.

If anyone knows how to remove such watermarks from a PDF really completely I try. But the watermark removing of the PDF tool itself is useless. They don't used the embedded function, they added a background text layer with this informations.

Re: Advant Scan

I already done it with other Kaba documents that had the "confidential" marking. Open PDF in word, find&replace worked fine for me. Also save as RTF removes most of the formatting if not relevant.
Edit: Not sure if relevant, are you in Switzerland ? Maybe we can meet.

That was my first attempt. But by edititing the RTF file in raw format, I noticed the branding-fragments inside. Lets say if the name is "Microsoft" you can find encapsulated text objects names "Mi", "cros", "oft" and so on in different combination. This makes ist simply impossible to do just a quit finde&replace.
And maybe theres more inside (possibly a non visible watermark in pictures). My attemps than was to remove the brandings how are visible, than convert every page to grayscale pictures and than convert it back to PDF with OCR. I tried this for a few pages: Time consuming... sad

Re: Advant Scan

Tested works flawlessly here :

Download qpdf  - http://qpdf.sourceforge.net/

Run :

\qpdf-6.0.0\bin\qpdf.exe --linearize --stream-data=uncompress source.pdf  dest.pdf

Open with notepad, find & replace watermark.
You can repair the file :

\qpdf-6.0.0\bin\qpdf.exe --linearize --stream-data=uncompress dest.pdf  repaired.pdf

If now working please provide a sample of your and will do a custom Python script to remove it.

Re: Advant Scan

The tool didn't work as well (still fragments)... I used a different way, since I tries to un-brand the files again. It took some time to convert, but now the files are clean.
Some of you got a Mail.

Re: Advant Scan

Thanks, still trying to make a valid badge on my side. The lua isn't of any help keep generating dumps that won't read after.
Edit: Tried with the CRc change in segment Zero. Will try on monday smile
