U.S. authorities announced five new arrests in an alleged US$45 million cyber attack on the financial industry.

The U.S. attorney for the Eastern District of New York, Loretta Lynch, Monday announced the arrests in connection with a so-called “cyber heist” that inflicted $45 million in losses on the global financial system.

It’s alleged that the new defendants in the case — Anthony Diaz, Saul Franjul, Saul Genao, Jaindhi Polanco and Jose Angeley Valerio — were members of an international cybercrime organization that hacked into the systems of financial institutions, stealing prepaid debit card data, and making fraudulent ATM withdrawals.

The indictment unsealed today charges the five with conspiracy to commit access device fraud. They each face up to seven and a half years in prison on the charge, as well as forfeiture and a fine of up to $250,000. They will be arraigned later on Monday. The allegations have not been proven.

Additionally, three of the original defendants were also charged Monday. Four others have pled guilty to charges in the case, and an eighth original defendant has since died.

According to U.S. authorities, on December 22, 2012, hackers penetrated a credit card processor’s computer network, compromised prepaid debit card accounts and operated a coordinated ATM withdrawal campaign. In total, more than 4,500 ATM transactions were conducted in approximately 20 countries around the world, resulting in approximately $5 million in losses. Then, in February 2013, the hackers again compromised prepaid debit card accounts and operated another coordinated ATM withdrawal campaign. Over the course of approximately 10 hours, cybercells in 24 countries withdrew about $40 million from ATMs, they report.

“This case is another example of the ability of cybercriminals to inflict significant damage to world financial systems,” said Steven Hughes, special agent in charge, U.S. Secret Service, New York Field Office. “This investigation and the resulting indictments should serve as a reminder to cybercriminals that law enforcement will continue to utilize cutting-edge investigative techniques, traditional tactics and hard work to thwart complex transnational cybercriminal activity.”
