This is not the first time this has happened with the ATM. previously there were many ATM got compromised.
Since automated teller machines (ATMs) made their grand entrance in the country, scams like the matchstick trick, glue stick trick, thermo-cam trick, skimmer trick, shoulder surfing trick, sleek trick at pouch, and sleek trick at the cash dispenser unit began surfacing as conmen used all kinds of methods to obtain cash fraudulently from the machines.

Hackers may have use the skimmer trick in this PNB HACK as it is most widely used technique in the recent days. Anybody can be the victim of this technique bcoz hackers place the fake card terminal in place of original one
What is a card skimmer, exactly?
A skimmer is a device that thieves attach to an ATM or a payment machine to trick people who are swiping their credit cards or debit cards.
The device attaches to (or over) the space where your card is normally inserted, and reads the information — which thieves then can use to compromise your accounts.
Often, if the target is debit cards, the skimming device is set up on the ATM, along with a nearby camera or person watching you enter your PIN
Shoppers can also victimized, with fake “overlay” pieces fitted over real payment machines at stores.
If they steal your debit card information and your PIN, fraudsters have everything they need to wipe you out — or make their money by selling your data to the next thief down the line
What does a card skimmer look like?
One giveaway that you might be at risk is if a terminal looks especially wide — since any overlay skimmer piece will inevitably take up extra space.
Indoor ATMs within your bank are not impervious to skimmers, but given the constant presence and supervision of bank employees, they are less likely to become compromised or remain compromised for an extended period of time.
