Hi,
Am a beginner here, anyway here's the scenario.

There are a bunch of financial POS servers running a system called Radi**t which logs EMV Tracks, in a Derived User Key Per Transaction DUKPT format.

I could read the tracks which is on filenames with extension .emv, .log, .dmp, which are 201 and 221 formats, but not the pin.

I have FULL Administrator access on the server as of today i checked; got my ex-girlfirend to cough out the access username and password (she has left the company though).

The pinpads are connected on serial and lan connection from the financial server, which brings to my question;

How can i sniff the pin in cleartext format?
 
Impossible , PINpad encrypt it and then it go to computer already encrypted.
