Largest Healthcare Data Breaches in 2020
2020 was the worst ever year for healthcare industry HIPAA compliance data breaches. Some 616 data breaches of 500 or more records were reported to the HHS’ Office for Civil Rights. 28,756,445 healthcare records were exposed, compromised, or impermissibly disclosed in those breaches, which makes 2020 the third worst year in terms of the number of breached healthcare records. The chart below clearly shows how healthcare industry data breaches have steadily increased over the past decade and the sharp rise in breaches in the past two years. The Largest Healthcare Data Breaches in 2020 When a breach occurs at a business associate of a HIPAA-covered entity, it is often the covered entity that reports the breach rather than the business associate. In 2020, a massive data breach was experienced by the cloud service provider Blackbaud Inc. Hackers gained access to its systems and stole customer fundraising databases before deploying ransomware. Blackbaud was issued with a ransom demand and a threat that the stolen data would be released publicly if the ransom was not paid. Blackbaud...
More Than 114,000 Patients Affected by Wilmington Surgical Associates Ransomware Attack
In October 2020, the NetWalker ransomware gang claimed responsibility for a ransomware attack on the North Carolina-based surgical center, Wilmington Surgical Associates. The gang claimed to have stolen around 13GB of data prior to deploying NetWalker ransomware and encrypting files. The stolen batch of data included thousands of documents containing sensitive information. HIPAA Journal has not yet been able to obtain a copy of the breach notification; however, the ransomware attack has now appeared on the HHS’ Office for Civil Rights breach portal and shows the PHI of 114,834 patients was compromised in the attack. The NetWalker ransomware gang targets healthcare providers and the gang has stepped up its attacks in 2020. The gang was behind the ransomware attack on the University of California San Francisco and stole sensitive and valuable research data. The University felt it had no alternative other than to pay the $1.14 million ransom to recover the encrypted data. Other healthcare providers attacked with NetWalker ransomware this year include the Crozer-Keystone Health System...
CISA Launches SolarWinds Supply Chain Compromise Website and Free Malicious Activity Detection Tool
The DHS’ Cybersecurity and Infrastructure Security Agency has launched a website providing resources related to the ongoing cyber activities of the advanced persistent threat (APT) group responsible for compromising the SolarWinds Orion software supply chain. The threat actors behind the attack gained access to the networks of federal, state, and local governments, critical infrastructure entities, and private sector organizations around the world. In addition to compromising the software update mechanism of SolarWinds Orion, the hackers also exploited vulnerabilities in commonly used authentication mechanisms to gain persistent access to networks. According to Microsoft, the main goal of the attackers appears to be to gain persistent local access to networks by delivering the Sunburst/Solarigate backdoor, then pivoting to victims’ cloud assets. Recently it has become clear that more than one threat group is conducting cyber espionage after the discovery of a different malware variant that was introduced through the SolarWinds Orion software update feature. Microsoft and Palo Alto...
Two Florida Healthcare Providers Attacked with Ransomware
The Tampa, FL-based Agency for Community Treatment Services, Inc. (ACTS) is alerting certain patients that some of their protected health information has potentially been compromised in an October 21, 2020 cyberattack. The security breach was detected on October 23 when ransomware was deployed. The hackers gained access to parts of the ACTS server and data infrastructure and encrypted files to prevent access. Systems were taken offline to prevent further unauthorized access and third-party computer forensic experts were engaged to assist with the investigation and determine the scope of the breach. While unauthorized data access was possible, the investigation did not uncover any specific evidence to indicate patient data had been accessed or exfiltrated. ACTS explained that this was due to the extensive efforts made by the attackers to conceal their malicious activity. The attackers may therefore have accessed or stolen information stored on the breached systems. The review of the compromised systems revealed they contained patient names, dates of birth, Social Security numbers,...
484,000 Aetna Members Impacted by EyeMed Phishing Incident
Aetna has announced more than 484,000 of its members have been impacted by a data breach at a business associate that provides services for members of its vision benefits plans. In July 2020, an unauthorized individual gained access to an email account of an employee of Cincinnati-based EyeMed and used the email account to send further phishing emails to individuals in the address book of the mailbox. EyeMed investigated the breach and determined the mailbox contained the protected health information of 484,157 Aetna members, 60,545 members of Tufts Health Plan, and 1,340 members of Blue Cross Blue Shield of Tennessee. No evidence of data theft or misuse of PHI was identified, although it was not possible to rule out data theft with a high degree of certainty. Affected health plans were notified about the breach in September. The compromised email account contained information such as members’ names, dates of birth, vision insurance ID numbers, health insurance ID numbers and, for a limited number of individuals, Social Security numbers, birth certificates, diagnoses, and...
