So they just plugged it directly into the same network switch the ATM is on? That sounds incredibly dumb. The only ATMs I've seen the inside of had the network switch locked inside with the vault.
Also our bank had some kind of port security so if it wasn't a recognized MAC address, the port just switched off.
And serious company will have this as basic security. It's a fundamental function even available on your consumer grade router at home. While it's overkill for that use, it's basic security for a company.
That's why it's not surprising at all that a bank didn't bother to do that. Banks have some of the most egregious security issues.
And really shitty auditors apparently. A good one would have at least spot checked for unsecured ports.
