NEW YORK — A bloodless bank heist that netted more than $45 million has left even cybercrime experts impressed by the technical sophistication, if not the virtue, of the con artists who pulled off a remarkable, internationally organized attack.
“It was pretty ingenious,” Pace University computer science professor Darren Hayes said Friday.
Seven people were arrested in the U.S., accused of operating the New York cell of what prosecutors said was a network that carried out thefts at ATMs in 27 countries from Canada to Russia. Law enforcement agencies from more than a dozen nations were involved in the investigation.
