Their said eight out of ten networks from hackers had taken last year in the line of fire.
Most likely source of attacks was from China, followed by Russia and the United States.
The number of reported incidents was higher than in 2009, when just over half the respondents said that she had fallen victim.
Denial-of-serviceThe form of distributed denial-of-service (DDOS) has most of the reported security breaches-attacks.
These include overwhelming a company typically a network of computers under the control of criminals, Internet connected systems.
While such incidents affect websites and corporate networks, researchers said it was unlikely that they were intended to cut off energy supply.
However, it remained a possibility that DDOS attacks according to Stewart Baker, a former U.S. National Security Advisor for President George W Bush and one of the authors of the report in the future could do more harm.
"We asked what was the likelihood of a major attack, caused the significant failure."
"This is one that causes severe loss of services for at least 24 hours, loss of life or personal injury or failure of a company."

"It probably obvious interference with the systems do not, because it was not designed to do this," said Mr Baker.
"But the fact that it so far as to spread and could have done if it had different designed is very, very disturbing, if you are concerned about cyber attacks by hostile Nations or blackmail attempts by well organized criminal gangs."
State aidSurveyed were also questioned, about how much involvement they had with their Governments to the fight against the cyber-security issues.
Japan came to the top, along with China and the United Arab Emirates, although the survey not questions, whether working voluntarily or was forced.
