About 120,000 Oregonians who are customers of Health Net are receiving letters about a data breach that may put their personal information at risk. Cheryl Martinis at the Oregon Insurance Division says they first heard about it in February, but the breech occurred in January. Health Net is working to help customers protect their personal information. Martinis says in addition to the credit monitoring service the letter outlines other steps customers can take to protect their information. Martinis says they don’t believe Health Net is in violation of any law.
