The recent cyberattack on Anthem, Inc., one of the largest health insurance companies in the United States, illustrates the persistence and severity of the risk of data breaches. On February 4, 2015, Anthem confirmed that one of its databases had been hacked. The data breach exposed personal information of approximately 80 million Anthem customers and employees—including names, birthdays, member health ID and Social Security numbers, street addresses, telephone numbers, e-mail addresses, and employment information—potentially the most damaging cyberattack to date on a health insurer.
Noting a pattern of medical data thefts from health insurers by foreign intelligence organizations, the FBI concluded that the attack was likely the work of Chinese hackers attempting to gain access to the networks of defense contractors and government workers. Moreover, while hackers have targeted healthcare providers, similar attacks on companies like Target, Sony, JP Morgan Chase, and Home Depot, signify the risk to all types of businesses.
One obvious implication for businesses that fall victim to these attacks—beyond negative press—is the exposure to liability for the resulting invasion on individuals’ privacy. For instance, individuals have already begun filing class action lawsuits for this particular breach, asserting that Anthem should be held responsible given its inadequate security measures—namely, its failure to employ encryption to prevent unauthorized access to their personal information.
