More than 75,000 computer systems hacked in one of largest cyber attacks, security firm says
The attack, which began in late 2008 and was discovered last month, targeted proprietary corporate data, e-mails, credit-card transaction data and login credentials at companies in the health and technology industries in 196 countries, according to Herndon-based NetWitness. News of the attack follows reports last month that the computer networks at Google and more than 30 other large financial, energy, defense, technology and media firms had been compromised. Google said the attack on its system originated in China.
