Default administrative credentials -- username and password were both "root" — gave full Telnet access to one machine, and it was possible to brute-force weak administrative credentials on the same model's remote web interface.

In both cases, it would be possible to send bogus processor-server responses to the machines, resulting in a cash jackpot. Some ATM models put the Ethernet port on the outside of the cabinet, making it possible to disconnect the cable and plug in a laptop that spoofed a processing server and told the ATM to spit out cash.

Known security flaws in the ATM's network hardware or software could also be exploited, as not all the ATMs had patched known flaws. Granted, it's not always easy to hang around an ATM and have enough time to pull off an attack. But the report noted that a crook would need only 15 minutes to access the ATM network connection to the processing center — something that might not be as conspicuous at three in the morning. Once you open up the cabinet and get access to the computer's input ports, there isn't much between you and a cash jackpot.

When you use an ATM, it's in "kiosk mode" and you can't switch to another application. But if you plug in a keyboard, or a Raspberry Pi set up to act like a keyboard, you can use the ATM like a regular computer. Exiting kiosk mode won't cough up the cash, but using a keyboard makes it a whole lot more convenient to run malicious commands on the ATM. Since more than half the machines examined ran Windows XP, the operating system with lots of known vulnerabilities, this wasn't always hard.

The researchers also found that two machines ran digital video recorder applications in the background to record customer activity. Once out of kiosk mode, the Positive Technologies team brought up the hidden DVR windows by moving a mouse cursor to a corner of the screen. Then they could use the DVR application to erase security footage. Most of the ATMs ran security appications to prevent installation of malicious software.

Four of those applications themselves, including two made by McAfee and Kaspersky Lab, had security flaws of their own. Another security application stored an administration password in plaintext. Also worth nothing is that although there are 10, possible four-number combinations between zero and nine, the report found more than 10 percent of all bank accounts can be hacked with just one guess.

So what was the least common combo? Knowing this does us no good now that the information is public, but what cues can we take from it?
