Chinese hackers attack computer systems of White House, US presidential candidates

Technical experts in the Obama camp later speculated that the hackers could be Russian or Chinese.

According to Sami Saydjari, CEO of the Cyber Defense Agency, a company that provides security consulting to governments, it is high time the US government took these cyber attacks seriously as they compromise the nation's security.

"I think we haven't made the proper investments in technology over the past few years," Saydjari said, adding that US may be behind countries such as China or Russia.

Agrees Michael Markulec, COO of Lumeta, a company that provides network security solutions to enterprise and government agencies. According to Markulec, hackings into government systems are not uncommon. "The threat is real, this is not the first time we've seen this and I would argue that in some cases, it's state-sponsored," Markulec said.

Meanwhile, the Chinese government has rubbished the allegations, claiming that it is as much a victim as a perpetrator in this cyber conflict.
