: Remove any unapproved copy of arqc-gen.exe from your network, report it, and verify that no unauthorized EMV key material has been exposed. Stay safe.

In a live production environment, ARQCs are only created by physical smart cards and validated by secure Payment Cryptography systems like AWS or physical Thales/Atalla HSMs. However, physical infrastructure is difficult to test programmatically.

Legitimate software from reputable financial software vendors is almost always digitally signed.

If you have found arqc-gen.exe on your system, it is advisable to treat it as a threat. How to Identify It: arqc-gen.exe
