Overview[]
Operation High Roller was a 2012 cyberattack against high-value commercial bank accounts, rich individuals, credit unions and large global banks and regional banks. It was reported that the attack siphoned around $78 million to $2.5 billion from bank accounts in Europe, the U.S. and Latin America. The attack located a victim's highest value account and transferred money to a prepaid debit card (which can be cashed in anonymously). The target's bank statement was then altered to hide the theft.
