CISA Launches Initiative to Improve Critical Infrastructure Resilience During Geopolitical Conflicts
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has announced a new initiative aimed at improving critical infrastructure cyber resilience during geopolitical conflicts, and is urging critical infrastructure operators to improve their defenses against disruptive and destructive cyberattacks through proactive isolation and recovery planning. CISA warns that adversaries have already embedded themselves in critical systems and are positioning themselves to cripple operational technology in the event of a wider geopolitical conflict. During geopolitical conflicts, critical infrastructure entities face an increased risk of cyberattacks, where nation-state actors may attempt to disrupt and destroy the operational technology running the United States. Attacks may target healthcare providers to disrupt patient care, telecommunications infrastructure to damage phone and internet services, food production facilities, and energy and wastewater entities. At all times, critical infrastructure entities must continue to deliver crucial services to Americans. They must therefore...
Healthcare Organizations Exposing Patient Data Via Poorly Secured DICOM Servers
Healthcare organizations are exposing a vast amount of patient data by failing to implement even basic security measures for DICOM servers, according to a recent Trend Micro TrendAI analysis. TrendAI identified thousands of internet-facing DICOM servers belonging to hundreds of entities. The lack of security protections puts patient privacy at risk and gives hackers the opening they need for lateral movement and ransomware attacks. Medical images generated from X-rays, MRI, CT, and ultrasound scans are captured, stored, processed, transmitted, and viewed using the Digital Imaging and Communications in Medicine (DICOM) standard. Work on a standard for communicating medical imaging information started in the early 80s and culminated in the DICOM standard. DICOM defines a file format for medical images and a network protocol for communicating those images between different devices and systems, including equipment such as scanners, workstations, and printers, software, network hardware, and Picture Archiving and Communication Systems (PACS). DICOM enables interoperability across...

Why Medical Couriers Are Always Classified as HIPAA Business Associates
Other than when they are directly employed by a covered entity, medical couriers are always classified as a HIPAA business associate due to the nature of the work they are contracted to do and their “operational access” to Protected Health Information (PHI), even when access only consists of a visible name, reference number, or address. Medical couriers play an important role in the healthcare system by transporting specimens, medications, lab results, and other items that support patient care. Because deliveries often involve sealed packages, it could be assumed that medical couriers do not qualify as business associates under the HIPAA conduit exception. This exception applies to entities that transmit PHI on behalf of a covered entity or business associate without storing it and without having anything more than transient, incidental access to PHI. Examples include the US Postal Service, UPS, FedEx, and Internet Service Providers who simply act as channels through which information flows. Why the Conduit Exception Does Not Apply to Medical Couriers Medical couriers, by contrast,...
Settlement Resolves FTC Lawsuit Against Kochava Over Sale of Geolocation Data
A settlement has been reached between the Federal Trade Commission (FTC) and the Idaho-based data broker Kochava and its subsidiary Collective Data Solutions to end long-running litigation over the sale of precise geolocation data. Kochava sells a range of data to its customers, which includes comprehensive consumer profiles and geolocation data. Kochava claims to be able to pinpoint an individual’s precise location to around 10 meters through GPS coordinates and other signals, which could be tied to an individual through a unique ID associated with their mobile device. Shortly after the Supreme Court decision that overturned Roe V. Wade and removed the federal right to an abortion, the FTC launched an investigation. The investigation prompted an August 2022 lawsuit, in which the FTC alleged that Kochava was selling consumers’ precise geolocation data that was collected without consumers’ knowledge or consent. The FTC alleged that the data provided by Kochava could be used to track the movements of individuals visiting sensitive locations such as reproductive healthcare facilities,...
