Premera Blue Cross (WA/AK) reported to HHS OCR on 2015-03-17 a Hacking/IT Incident affecting 11,000,000 individuals, with breached information located on Network Servers. Attackers used a phishing email in May 2014 to install malware enabling unauthorized access for ~9 months until January 2015 (advanced persistent threat). Exposed PHI included names, addresses, dates of birth, email addresses, SSNs, bank account information, and health plan clinical data for 10.4M+ individuals. PBC settled with OCR for $6.85M — the second-largest HIPAA resolution in OCR history — and agreed to a corrective action plan with two years of monitoring.
