Officers from the Metropolitan Police's Central E-Crime Unit (PCeU) have arrested a man and woman in their twenties in an investigation of an online Trojan virus called ZeuS, which threatened to compromise thousands of UK computers.
The ZeuS or Zbot Trojan enabled the distributors to harvest millions of lines of data from affected machines. Once installed, ZeuS recorded users' online bank account details and passwords, credit card numbers and other personal information, including passwords for social networking sites, before causing the computer to forward the data to servers under the control of the distributors.
The pair were arrested for offences under the 1990 Computer Misuse Act and the 2006 Fraud Act.
Both suspects were interviewed by PCeU detectives and have been bailed while further enquiries are completed.
Detective Inspector Colin Wetherill of the PCeU said, "The ZeuS Trojan is a piece of malware used increasingly by criminals to obtain huge quantities of sensitive information from thousands of compromised computers around the world. The arrests represent a considerable breakthrough in our increasing efforts to combat online criminality."
