Weak security is being blamed for the mammoth hack of one of the nation's largest health insurance providers, which has put the private data of 80 million people at risk. Investigators are focused on weak security for login credentials, as the hackers are believed to have accessed Anthem Inc.'s information by stealing the company system administrator's access information. "Anthem's primary security sin may not have been the lack of encryption, but instead improper access controls," security researcher Ken Westin wrote in a blog post. Hackers were able to get the credentials of five different Anthem tech workers, the country's second-largest health insurer, The Associated Press reported Saturday.
