Comprehensive LockBit Ransomware Cybersecurity Advisory Issued by CISA & Partners
The Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Multi-State Information Sharing and Analysis Center (MS-ISAC), and its international cybersecurity agency partners have issued a cybersecurity advisory about the LockBit ransomware operation, which has extorted $91 million from organizations in the United States since 2020 across 1,700 attacks. “This joint advisory on LockBit is another example of effective collaboration with our partners to provide timely and actionable resources to help all organizations understand and defend against this ransomware activity,” said CISA Executive Assistant Director for Cybersecurity, Eric Goldstein. “As we look to the future, we must all work together to evolve to a model where ransomware actors are unable to use common tactics and techniques to compromise victims and work to ensure ransomware intrusions are detected and remediated before harm can occur.” The LockBit ransomware-as-a-service operation is the most prolific RaaS group, having listed more victims on its data leak site than any other...
Ransomware Attack Key Factor in Decision to Close Rural Illinois Hospital
Ransomware attacks can cause healthcare facilities to temporarily close and small healthcare practices have made the decision not to reopen after a ransomware attack, but hospitals and health systems are usually financially resilient enough to remediate the attacks and recover, but not St. Margaret’s Health. Like many rural hospitals and health systems, St. Margaret’s Health has been struggling to maintain operations in the face of increasing financial pressures, then fell victim to a ransomware attack that sent it into a downward financial spiral. The attack, in combination with several other factors, resulted in the decision to permanently close its 44-bed Spring Valley location in Illinois. St Margaret’s Health also operates a 49-bed hospital in Peru, IL, which was under a temporary suspension that was announced in January this year. All operations at the two hospitals will permanently end on Friday, June 16, 2023. The Sisters of Mary of the Presentation founded St. Margaret’s Health in 1903, and in 2021, St. Margaret’s Hospital – Spring Valley and Illinois...
HPH Sector Urged to Make FIN11 Threat Group a Priority for Security Teams
The Health Sector Cybersecurity and Coordination Center (HC3) has compiled a profile of the FIN11 threat group (TA505/Lace Tempest/Hive0065) which is known to target organizations in the healthcare and public health (HPH) sector. Historically, FIN11 has conducted phishing campaigns but has now migrated to other attack vectors against companies in North America and Europe. The group is financially motivated and often engages in data theft for extortion, with or without ransomware. Recent attacks include the exploitation of zero day vulnerabilities in file transfer solutions to gain access to sensitive data, which is stolen and threatened to be released if a ransom is not paid. FIN11 often deploys CLOP ransomware in its attacks, although it is unclear exactly how many CLOP ransomware attacks FIN11 has conducted. The ransom demands in these attacks vary based on the perceived ability of the victim to pay and typically range from a few hundred thousand dollars to $10 million. FIN11 phishing and spear phishing campaigns have used a combination of malicious attachments and hyperlinks,...
Ransomware Attack Triggers Multiple Lawsuits Against Harvard Pilgrim Healthcare & Point32Health
Harvard Pilgrim Health Care and its parent company, Point32Health, are facing multiple class action lawsuits after hackers gained access to the protected health information (PHI) of more than 2.5 million individuals in an April 2023 ransomware attack. Point32Health is the second largest insurer in Massachusetts and serves more than 2.4 million customers. Point32Health was formed following the merger of Harvard Pilgrim Health Care and Tufts Health Plan in 2021. According to Point32Health, hackers gained access to Harvard Pilgrim’s systems on March 28, 2023, and maintained access to those systems until April 17, 2023, when the intrusion was detected and blocked. The attack was detected when ransomware was used to encrypt and prevent access to files. The forensic investigation confirmed the affected systems contained PHI such as names, addresses, phone numbers, birthdates, health insurance account information, Social Security numbers, provider taxpayer ID numbers, and clinical information and that information was in the files exfiltrated from its systems. Credit monitoring and...
320,000 Patients Affected by Ransomware Attack on Onix Group
The Pennsylvania-based business administration service provider, Onix Group, was the victim of a ransomware attack on March 27, 2023. When the incident was detected, its network was immediately taken offline to prevent any further unauthorized access; however, the attackers were able to encrypt files on certain systems. The forensic investigation confirmed that access to its systems was gained 7 days before ransomware was deployed and files were encrypted, and during those 7 days the cyber actors exfiltrated files containing sensitive data. The review of the files confirmed they contained the data of patients of healthcare clients Addiction Recovery Systems, Cadia Healthcare, Physician’s Mobile X-Ray, and Onix Hospitality Group. The protected health information in the stolen files varied from individual to individual and may have included names, Social Security numbers, dates of birth, and scheduling, billing, and clinical information. Some of the files contained client information that was stored for HR purposes, including employees’ names, Social Security numbers, direct...
