7 Major Cyber Security Incidents Targeting the Healthcare Industry

Nowadays, the target of cyber attackers is money and information from as many people as possible. Therefore, the areas where the most personal information is collected become the target. Each person's data is unique to him, and people cannot easily change some of this information, such as credit card, phone number, and identity information.

This article will list and tell you the most significant cyberattacks in the health sector. Good reading.

 

1.Anthem Medical Data Breach

A company that makes health insurances called Anthem BlueCross BlueShield was exposed to a massive cyberattack in February 2015. Attackers stole the data of 78.8 million people in this attack. In a statement made by the company's CEO, he stated that we faced a very sophisticated attack. Attackers gained unauthorized access to the IT system. They leaked many personal data, such as names, birthdays, medical IDs / social security numbers, open addresses, e-mail addresses, and income data of current and former members.

After the investigation, it is stated that the data breach began on February 18, 2014, when a user at one of an Anthem-working subsidiary opened a malicious phishing e-mail.

Opening the e-mail initiated the download of malicious files to the user's computer and allowed attackers to gain remote access to this computer and dozens of different systems from Anthem, including Anthem's data center.

Attackers used at least 50 accounts in the Anthem corporate network, and eventually, at least 90 different systems were compromised, including the data center. Attacks on this data center caused 78.8 million users to leak.

After the data breach, Anthem implemented more penetration tests on its network and systems, allowing users to reset all their passwords. Also, they added a two-factor authenticator to their system.

AMCA stated that it was subject to a massive cyberattack in an estimated period from August 1, 2018, to March 30, 2019. The number of people affected by this attack is approximately 25 million people and 18 healthcare providers.

Premera Blue Cross has become one of the biggest breaches in the healthcare industry, announcing the theft of personal, financial, and medical information of more than 11 million customers. Research on this attack revealed that the first attack started on May 5, 2014.

 

The attack started with the opening of phishing e-mails and then downloading the malware in the contents of these e-mails, just like the attack on Anthem Medical. This malware was an advanced threat that cannot be detected. Attackers stone many personal information such as customers' names, addresses, birth dates, e-mail addresses.

After this attack, a federal district judge approved a proposed $ 74 million deal to settle a consolidated class action for 11 million records against Premera Blue Cross. According to the agreement, Premera Blue Cross will allocate $ 32 million for people affected by the breach, and $ 10 million of this $ 32 million will be spent to cover the costs of the violation.

Investigations about the attack indicated that the attackers first started the attack on December 23, 2013, but since then, the attack has been working unnoticed. It was emphasized that the attackers had unauthorized access to the company's Information Technology Office and obtained data from there.

As a result of this attack, there are class actions brought against the company by the violation victims. The reason for filing these class action lawsuits stems from the leak of personal and health information. After the lawsuits, Excellus reported that it lost around 100,000 customers in 2015. At the same time, the cost of the attack is stated as 17.3 million dollars.
