A 30-year-old Ukrainian man has been arrested in Greece on suspicion of being a member of an international ring that stole Internet user bank details to withdraw money from their accounts, the electronic crimes squad said yesterday. The unnamed man allegedly worked for a gang based in St Petersburg, Russia. The gang attaches a Trojan horse program to e-mails that it sends to potential victims. If the messages are opened, the program installs itself on the user’s computer and gives the sender access to personal information, including the victim’s bank details. Police did not indicate how many people the 30-year-old had targeted but said that he had managed to steal 6,000 euros from a man in Germany. The suspect would keep a percentage of the money he stole and send the remainder to the gang in Russia, police said.
