University Medical Center of Southern Nevada Suffers REvil Ransomware Attack
University Medical Center of Southern Nevada (UMC) has suffered a ransomware attack in which patient data was stolen. The medical center confirmed it identified suspicious activity within the hospital network in mid-June and took immediate action to contain the threat and restrict access to its servers. The investigation into the cyberattack is continuing and law enforcement has been notified. At this stage it appears that the attackers targeted a server that was used to store patient data. The investigation is still in the early stages, but UMC said it appears that clinical systems were not affected. UBM said it is working with the Las Vegas Metropolitan Police Department, the FBI, and third-party cybersecurity experts to determine the exact origin and scope of the breach. Any cyberattack that causes disruption to hospital operations has potential to result in considerable harm to patients. This is especially true for an attack on UMC, which runs the only Level 1 trauma center in Nevada. UMC said the fast action of its IT department helped to contain the breach, but that response...
CISA Publishes Catalog of Cybersecurity Bad Practices That Must Be Eradicated
The DHS’ Cybersecurity and Infrastructure Security Agency (CISA) has published a new resource that lists cybersecurity bad practices that are exceptionally dangerous and significantly increase risk to critical infrastructure. There are many published resources that provide information about cybersecurity best practices that should be adopted to improve security, but CISA felt an additional perspective was required as it is equally, if not more, important to ensure that bad cybersecurity practices are eliminated. “Ending the most egregious risks requires organizations to make a concerted effort to stop bad practices,” explained CISA. CISA is urging leaders of all organizations to engage in urgent conversations to address technology bad practices, especially organizations that support national critical functions. One of the foundational elements of risk management is “focus on the critical few”, explained CISA Executive Assistant Director Eric Goldstein in a blog post announcing the launch of the new website resource. Organizations may have limited resources to identify and mitigate...
OIG Survey Reveals Lack of Oversight of Cybersecurity of Networked Medical Devices in Hospitals
The HHS’ Office of Inspector General (OIG) has conducted a review to determine the extent to which the Centers for Medicare and Medicaid Services (CMS) and Medicare Accreditation Organizations (AOs) require hospitals to have implemented a cybersecurity plan for networked devices and the methods used to assess the cybersecurity of networked medical devices. Cybersecurity controls are required to protect medical devices that are connected to the Internet, other medical devices, or internal hospital networks. Without those controls, the devices could be accessed by unauthorized individuals and patients could be at risk of harm. Networked medical devices include MRIs, computed tomography, ultrasound, nuclear medicine, and endoscopy systems, as well as systems that communicate with clinical laboratory analyzers such as laboratory information systems. OIG cited an estimate that a large hospital may have around 85,000 medical devices connected to its network. These devices are usually separated from other systems, they may connect to the same network as the electronic health record (EHR)...
NIST Publishes Critical Software Definition for U.S. Agencies
President Biden’s Cybersecurity Executive Order requires all federal agencies to reevaluate their approach to cybersecurity, develop new methods of evaluating software, and implement modern security approaches to reduce risk, such as encryption for data at rest and in transit, multi-factor authentication, and using a zero-trust approach to security. One of the first requirements of the Executive Order was for the National Institute of Standards and Technology (NIST) to publish a definition of critical software, which the Cybersecurity and Infrastructure Security Agency (CISA) will use to create a list of all software covered by the Executive Order and for creating security rules that federal agencies will be required to follow when purchasing and deploying the software. These measures will help to prevent cyberattacks such as the SolarWinds Orion supply chain attack that saw the systems of several federal agencies infiltrated by state-sponsored Russian hackers. The Executive Order required NIST to publish its critical software definition within 45 days. NIST sought input from...
Government Watchdog Makes 7 Recommendations to HSS to Improve Cybersecurity
The Government Accountability Office has published a report following a review of the organizational approach to cybersecurity of the U.S. Department of Health and Human Services (HHS). The study was conducted because both the HHS and the healthcare and public health sector are heavily reliant on information systems to fulfil their missions, which include providing healthcare services and responding to national health emergencies. Should any information systems be disrupted, it could have major implications for the HHS and healthcare sector organizations and could be catastrophic for Americans who rely on their services. “A cyberattack resulting in the disruption of IT systems supporting pharmacies, hospitals, and physicians’ offices would interfere with the approval and distribution of the life-saving medications and other products needed by patients and healthcare facilities,” said the GAO in the report. The HHS must implement safeguards in place to protect its computer systems from cyber threat actors looking to obtain sensitive data to commit fraud and identity theft,...
