The attack, originating from a crime ring based in Eastern Europe, shows that criminal groups are becoming as sophisticated in their cyberattacks as nation states such as China and Russia, the Washington Post reports. The attack, which began in late 2008 and was discovered last month, tricked unsuspecting computer users at the targeted companies into downloading infected software or opening emails with infected attachments. A malicious software intrusion called the Kneber bot then trolled users' computers for log-in information and passwords, which it used to get into other users' systems, multiplying its attack exponentially. The log-in data the hackers gathered has monetary value in the criminal world.
