The Federal Bureau of Investigations has arrested over 100 members of a gang of cyber-crinminals who collectively stole £44.4 million by hacking into computers in the US.
Nineteen members of the gang have also been arrested in the UK and five in the Ukraine.
The fraud came to light after the FBI noticed suspicious trends in bank transactions in Omaha.
It is believed that those arrested were ‘mules’ who provided bank accountants.
These were used by hackers in Eastern Europe who infected US computers with Zeus financial malware via spam email.
This gave them access to passwords and bank details, allowing them transfer money into the bank accounts created by the go-betweens.
The international operation which led to the arrest of the criminals was known as “Operation ACHing Mule”, referring to the use of Automatic Clearing House fraud to transfer the money, as well as the use of the mules.
