Anthem Hack May Have Involved Millions Who Aren’t Customers

Social Security numbers, names and addresses for millions of people who aren’t customers of Anthem Inc. may have been breached in a massive cyberattack disclosed by the health insurer earlier this month.

Anthem, which runs Blue Cross and Blue Shield plans in 14 states, believes information on 78.8 million people was accessed by hackers. Of those, about 60 million to 70 million were customers of the Indianapolis, Indiana-based insurer, spokeswoman Kristin Binns said in an e-mailed statement Tuesday.
