Most third-party breaches end with a dataset for sale on a forum. The RBS WorldPay breach ended with people standing in front of ATMs in 280 cities.
RBS WorldPay was the US payment processing arm of the Royal Bank of Scotland. Among its product lines was a payroll card platform that allowed employers to load wages onto reloadable prepaid cards instead of issuing paper cheques or running bank transfers. The cards were used by workers to draw their wages at ATMs.
Between Christmas Eve and Christmas Day 2008, attackers who had been inside RBS WorldPay's processing environment for weeks pushed their plan into operation. They raised the balance ceilings on a small set of compromised payroll card accounts to seven-figure US-dollar values, distributed cloned cards to a cash-out crew of more than 100 people, and triggered a synchronized withdrawal spree across 280 cities. The whole operation completed in under twelve hours. By the time RBS WorldPay's anti-fraud systems converged on a coherent picture, the cash was gone.
