Russian phishers managed to steal 800,000EUR (roughly $1 million) from Swedish bank Nordea by tricking users into downloading and installing a Trojan horse on their PCs that steals their account login details:
Hackers targeted the bank's customers with emails purporting to be from Nordea that told them to download an anti-spam tool. But those who downloaded the attachment were infected by the Trojan 'haxdoor.ki'.
The malicious software activates itself when the customer tries to log on to Nordea's internet banking service and displays an error message asking the customer to re-enter their login information, which is then recorded and sent to servers belonging to the hackers.
Swedish police have traced the attacks to Russia, via servers in the US, and have arrested more than 100 middlemen in Sweden already, the bank said.
Nordea Bank compensated all customers in full and is looking to improve the security of their online banking service.
