The California Department of Insurance has released its examination findings and a settlement agreement concerning the cyber security breach of health insurer Anthem Inc., which compromised 78.8 million consumers' records.

Anthem has agreed to make a number of enhancements to its information security systems and also has agreed to provide credit protection to all consumers whose information was compromised.

Anthem also is paying more than $260 million for security improvements and remedial actions in response to the breach.

“This was one of the largest cyber hacks of an insurance company's customer data,” said California Insurance Commissioner Dave Jones, one of seven insurance commissioners leading the national investigation of the Anthem cyber breach. “Insurers have an obligation to make sure consumers' health and financial information is protected. Insurance commissioners required Anthem to take a series of steps to improve its cybersecurity and provide credit protection for consumers affected by the breach.

“In this case, our examination team concluded with a significant degree of confidence that the cyber attacker was acting on behalf of a foreign government. Insurers and regulators alone cannot stop foreign government assisted cyber attacks. The United States government needs to take steps to prevent and hold foreign governments and other foreign actors accountable for cyber attacks on insurers, much as the president did in response to Russian government sponsored cyber hacking in our recent presidential election,” Commissioner Jones added.

The cyber breach first was discovered by Anthem on January 27, 2015. In early February 2015, Anthem and its affiliates announced the company had suffered a major breach, which compromised 78.8 million consumer records, including records of at least 12 million minors.

An investigation by the insurance commissioners' examination team and a separate internal investigation by Mandiant, an information security firm hired by Anthem, revealed the data breach began on February 18, 2014, when a user within one of Anthem's subsidiaries opened a phishing email containing malicious content. Opening the email permitted the download of malicious files to the user's computer and allowed hackers to gain remote access to that computer and at least 90 other systems within the Anthem enterprise, including Anthem's data warehouse.

The lead insurance commissioners employed an examination team composed of the cybersecurity firm CrowdStrike and Alvarez & Marsal Insurance and Risk Advisory Services, LLC.

The team determined with a high degree of confidence the identity of the attacker and concluded with a medium degree of confidence that the attacker was acting on behalf of a foreign government. Notably, the exam team also advised that previous attacks associated with this foreign government had not resulted in personal information being transferred to non-state actors.

Within two weeks of discovering the breach and following discussions with the lead states, Anthem hired AllClear ID, a consumer credit protection company, to offer credit protection services to all breach-affected consumers for a two-year period. Additionally, as a result of the multi-state settlement, Anthem has agreed to offer a credit protection solution to all minors who were under age 18 when the security breach occurred.
