Anthem Data Breach: 6 Key Points to Understand

In a significant cybersecurity incident, Anthem, the nation’s second-largest health insurance provider, disclosed on Wednesday that cybercriminals have compromised the personal information of more than 80 million individuals. This breach surpasses the scale of the infamous Target data breach in 2013, which involved stolen payment card data for 40 million customers.

The leaked information encompasses a wide array of sensitive data, including residential addresses, birth dates, medical identification numbers, Social Security numbers, email addresses, and some income details pertaining to both current and former customers as well as employees, including leadership personnel.

To put the impact into perspective, 80 million is almost equal to the combined populations of California, Texas, and Illinois. As of now, no evidence has surfaced indicating that financial or medical information was specifically compromised, according to Kristin Binns, Anthem’s vice president.

In response to the attack, which originated at its Indianapolis headquarters, Anthem has engaged Mandiant, a cybersecurity firm under FireEye, to determine the scope of the breach and the identities of affected customers. However, the attackers remain unidentified, underscoring a significant failure in the company’s cybersecurity measures.

The question arises: What vulnerabilities allowed an organization like Anthem to expose 80 million customers to such a massive cybersecurity attack? Experts suggest that the breach may be rooted in insufficient security measures, specifically a lack of data encryption that could have adequately protected sensitive information stored in the company’s databases.

While Anthem has not attributed the attack to a specific group, some security analysts have raised concerns that it reflects a pattern, as Chinese hackers have shown a history of targeting major health insurance companies. The method of intrusion likely involved a sophisticated malware application that garnered unauthorized access to user credentials, thus facilitating the breach of sensitive customer data.

Following this incident, Anthem issued warnings to current and former customers regarding potential email scams capitalizing on the breach, urging vigilance against malicious actors attempting to solicit personal information under the guise of offering credit protection services. The insurer emphasized that official communications would only be conducted through traditional mail and that no representatives will solicit sensitive data via phone or email.

Despite Anthem’s assurances that hackers did not appear to obtain medical data, the compromised information still opens doors to potential medical identity theft and fraud, particularly as medical identification numbers can be detrimental in the hands of cybercriminals. Security analysts have noted alarming trends, with over 90 percent of healthcare organizations having confronted data breaches in the past two years, as reported by the Ponemon Institute, highlighting a systemic issue within the sector.

In light of these repeated breaches involving major companies like Target, Home Depot, and Anthem, there are intensified demands for legislative action aiming to establish robust cybersecurity frameworks. Experts such as Waldo Jaquith advocate for federal legislation mandating stronger security protocols, including more sophisticated password requirements and multi-factor authentication processes that could mitigate future risks until systemic changes are implemented.

As this situation continues to evolve, affected customers are urged to remain proactive in monitoring their accounts and utilizing available identity protection services. They must stay vigilant against any signs of identity theft, as the risk from this breach is not confined to a short-term window. Individuals should consult Anthem’s dedicated resources for further guidance relating to this breach and ensure they are informed of any updates pertaining to their personal data security.
