Chinese government and freelance hackers are the primary culprits behind as many as several hundred daily attacks against U.S. government, electric-utility and financial computer networks, a senior congressman said. "Sophisticated hackers could really wreak havoc on our financial systems if they were successful," House Homeland Security Committee Chairman Bennie Thompson (D-Miss) said. The threat is "primarily from China." While cyber plots to disrupt U.S. computer networks have been thwarted, significant vulnerabilities exist, said Rep Thompson.
