–Online Crime Gang Steals US $13 Million in One Day
(August 26)
A security breach at a Florida based debit card processing company,
Fidelity National Information Services Inc. (FIS), resulted in criminals
using cloned prepaid debit cards to withdraw US $13 million from ATMs
around the world over a 24 hour period. The criminals had previously
gained access to Fidelity National Information Services Inc.'s prepaid
debit card database and cloned 22 cards which were sent to conspirators
in different countries. At the close of business on Saturday May 5, the
criminals coordinated to withdraw the money over the next 24 hours from
ATMs in countries such as Greece, Russia, Spain, Sweden, Ukraine and the
United Kingdom. When the prepaid balance on each debit card reached its
limit, the criminals remotely updated the balance on each card. It is
not clear who was behind the attack, but journalist Brian Krebs, who
investigated the breach in detail, said the attack has the
characteristics of Russian or Easter European based criminal gangs
