Hackers, believed to be Russian nationals, stole around $2.2 million from ATMs in Taiwan. Police say they used a connected device, but no bank card, to work several ATMs of First Bank. Three malware strains reportedly showed up on the breached machines. Several banks in Taiwan have suspended their ATM operations while investigation continues. The hackers may have used a weak wireless service to access ATMs, says security expert Craig Young of security tools firm Tripwire, who says it was likely they had installed malware ahead of time.”]
