MANILA, Philippines – Hackers attacked Anthem, the US’ second-largest health insurer, gaining access to a database that reportedly housed records for 80 million people.

According to a Wall Street Journal report, Anthem said the hackers were able to obtain names, birthdays, addresses, and Social Security numbers from the database. It did not not appear, however, that medical information or financial details were taken.

Anthem said it discovered the security breach only a week ago, when a systems administrator noticed a database query being run under his name without his knowledge.

The company said it is unsure how many records were taken, though it added the data has not yet reached the black market.

David Damato, managing director at the company that Anthem hired to investigate the breach, said the attack was “sophisticated” and took advantage of advanced custom tools.

The Verge added that the Anthem breach was the latest in a string of attacks targeting large corporations, such as eBay, Home Depot, and Adobe. – Rappler.com
