On February 20th, 2013, a group of criminals stole $40 million from ATMs across the world.
The heist came in two parts: first, a quiet hack of a payment processor to raise withdrawal limits on specific cards, then a mad dash to withdraw as much cash as possible before the processor caught on.
By the time the processor fixed the hack, criminals had made 26,000 withdrawals across 24 different countries.
Not all of the cashers knew each other, but they were brought together by the economics of the criminal marketplace.
Stealing ATM card information is a major business, and thieves are eager to get as much money as possible for each card.
