Personal information of 18.5 million California residents, almost half of the state's total population, suffered from a data breach due to hacking, theft or other personal data exposure in 2013. Up to one-third of the total suffered from some form of fraud, California Attorney General Kamala Harris said - with the 167 significant breaches and 18.5 million number six times higher than 2.5 million accounts stolen in 131 reported breaches one year earlier.
Not surprisingly, the Target breach contributed to the significant increase, but as cybersecurity experts warned, a number of companies are suffering from large scale data breaches.
"Data breaches... threaten the privacy, the security and the economic well-being of consumers and businesses," Harris said. Cybercriminals don't prefer residents in California over other states, but the California Data Breach Report forces businesses and government agencies to publicly disclose breaches of more than 500 people.
