Hackers got into the data of a major health insurer in June 2014. Perhaps a million customers affected. Breach was just announced, having gone undiscovered for more than 9 months.
“Hackers Accessed Data From Insurer CareFirst,” Wall Street Journal, May 21, 2015 B2. Third health insurer breach reported this year. This one in the DC area. Were federal employees affected? Don’t know. Yet. Looks like Chinese hackers.
How quickly would you like to know that your name, email, address, and other information had been hacked? I assume 11 months is “too long.” The information that was hacked was the information the customers used to access services at the insurer.
