It looks like a Mifare Classic, which will be good news and normally pretty straight forward.
Lets first do a TagInfo scan to confirm what you are dealing with.
As you have a Proxmark, let’s focus on that primarily.
There are many places we can start, but let’s make sure the firmware is upto date
cd proxmark3git pullmake clean && make allORmake -j(it will allow for parallel compiling and goes faster. - Thanks @ Iceman) ORmake -j4(for compiling in parallel on all cores - Thanks @ equipter)./pm3-flash-bootrom./pm3-flash-fullimagepm3
That should be you all updated
Then we will test the hardware antennas, make sure they return as good
hw tune
Then when that’s done, lets do a
hf search
