The employees at the solutions center did not follow established guidelines for password reset requests and successfully changed the passwords for the hacker. The PHI involved included names, member identification numbers, claims and health insurance information, and other treatment information. The CE notified HHS, affected individuals, and the media. In response to the breach, the CE sanctioned the responsible employees, implemented additional technical safeguards, updated its policies and procedures, and retrained its staff.
