Chinese Hackers Viewed White House E-Mail
The White House computer network has been penetrated several times by Chinese hackers who viewed e-mails between officials, a senior U.S. official says.
The cyber attackers got into the White House system for brief periods that allowed theft of information before U.S. government experts patched the system, the Financial Times was told.
The government official stressed that the hackers got into the unclassified computer network and not the more secure classified network.
Experts say they suspect the Chinese government sponsored the intrusion but had no proof of that.
. The United States has increased efforts to improve cyber security, especially since Chinese hackers penetrated the Pentagon system last year.
Further, investigations have determined that a cyber attack this summer on the Obama and McCain campaign computer networks originated in China.
