A new report shows that hackers have exposed the personal information of 110 million Americans - nearly half the country's adults - in the past year, CNNMoney reported.

 

The research was conducted for CNNMoney by Ponemon Institute.

 

The number of accounts hacked is estimated to total 432 million, according to data tracked by the Identity Theft Resource Center and CNNMoney's own review of corporate disclosures.

 

Researchers at the IT company Unisys assert that hacks are becoming so commonplace that we're experiencing "data-breach fatigue," or becoming numb to the risk.

 

But "the damage is real," the article says. Stolen records typically include a person's name, credit card information, telephone number and passwords.

 

The increase in security breaches is likely a factor of people moving more information online and hackers getting more sophisticated, the article says.

 

Another survey released today offers additional sobering information. In a survey of 500 U.S. businesses, law enforcement services and government agencies, three out of four respondents said they had detected a security breach in the past year, Daily Finance reported.

 

Perhaps more disconcerting, 28 percent of the respondents said the attacks were coming from the inside, either from contractors, current or former employees, or service providers.

 

The survey was co-sponsored by San Jose-based business consulting firm PwC, the U.S. Secret Service, the CERT Division of Carnegie Mellon University's Software Engineering Institute and CSO security news magazine.
