On Monday, February 23, 2015, Anthem, Inc. released its Cyber attack State Impact Report. Anthem's initial analysis indicates that approximately 13.5 million consumers in California were affected by this cyber attack.

Blue Shield of California members affected Preliminary figures suggest that approximately 59,000 of Blue Shield of California's 3.4 million members were affected by the breach. There remains a small subset of affected Blue plan members who have not yet been identified. Should we find out that any of those members are current or former Blue Shield of California members, they will be notified as soon as possible.

  • They are current or former Blue Shield of California members who received healthcare services over the past 10 years in any of the areas that Anthem's Blue Cross Blue Shield companies serve.

  • They are current or former Anthem or Anthem Blue Cross members.

The information accessed may have included names, dates of birth, Social Security numbers, healthcare ID numbers, home addresses, and email addresses. Anthem has advised Blue Shield of California that no credit card or banking information was compromised, nor is there evidence that medical information such as claims, test results, or diagnostic codes were targeted or obtained. Anthem reports no evidence that any of this information was misused in any way.

According to Anthem, broker information was not affected by this breach.
