Anthem Blue Cross

Anthem Blue Cross

The California Office of the Attorney General reported a data breach involving Anthem Blue Cross on November 20, 2013. The breach occurred due to a PDF document posted on the Anthem website from October 23, 2013, until October 24, 2013, which erroneously displayed provider Tax Identification Numbers. The affected information included names, business addresses, and potentially Social Security Numbers, although it was stated that there was no reason to believe the Social Security Numbers had been compromised.
