Anthem: Hackers tried to breach system as early as Dec. 10

SAN FRANCISCO (AP) — The hackers who stole millions of health insurance records from Anthem Inc. commandeered the credentials of five different employees while seeking to penetrate the company’s computer network — and they may have been inside the system since December.

Anthem said this week that hackers stole names, Social Security numbers and other sensitive information for up to 80 million Anthem customers, in a breach that was first detected on Jan. 27. That’s when an Anthem computer system administrator discovered outsiders were using his own security credentials to log into the company system and steal data.
