A computer hacker accessed names and Social Security numbers of about 1.4 million Californians after breaking into a University of California, Berkeley, computer system in perhaps the worst attack of its kind ever suffered by the school, officials said Tuesday.
"The investigation is continuing but we have no idea if the (personal) information has been compromised," said Carlos Ramos, assistant secretary at the California Health and Human Services Agency. He said state agencies and the FBI were investigating, but the hacker had not been found. The names accessed by the hacker were being used by a UC Berkeley researcher who had collected data on elderly people and individuals who provide in-home care to seniors to study the impact of wages on in-home care, Ramos said.
