Healthcare Organizations Struggling to Implement Primary Method of Blocking Lateral Movement
A study of security leaders from the healthcare and manufacturing industries found that while there is an almost universal desire to deploy modern microsegmentation, more than 90% of respondents said they had protected fewer than 80% of critical systems, despite almost half admitting to falling victim to lateral movement attacks in the past year. In healthcare, fewer than 6% of respondents said that their organization had implemented microsegmentation across 80% or more of their critical systems. Microsegmentation is a cybersecurity technique that divides networks into small, distinct, and isolated zones to secure workloads, applications, or devices. Traditional network segmentation, such as Virtual Local Area Networks (VLANs), creates broad segmented zones, whereas microsegmentation applies security policies at the individual workload or application level. Microsegmentation allows organizations to implement East-West traffic control within their data center, rather than only North-South traffic controls for identifying traffic leaving the network. It provides deep visibility into...
SAG-AFTRA Health Plan Settles Lawsuit Over 2024 Phishing Incident
SAG-AFTRA Health Plan has settled a class action lawsuit over a September 2024 email data breach for $950,000. Hackers gained access to the health plan’s email systems between September 17 and September 18, 2026, after employees responded to phishing emails. The attack exposed sensitive personal and protected health information, which was potentially copied by the hackers. Data compromised in the incident included names and Social Security numbers and, for some individuals, health information, claims information, and plan participant identification numbers. The breach was reported to the HHS’ Office for Civil Rights initially as affecting 35,592 individuals, although that total was later increased to 98,474 individuals.

Former FBI Deputy Cyber Chief Calls for Terrorism Classification for Healthcare Ransomware Actors
At a recent joint hearing by the Subcommittee on Border Security and Enforcement and the Subcommittee on Cybersecurity and Infrastructure Protection, a former FBI cyber chief called on the U.S. government to consider applying terrorism designations to ransomware actors who attack hospitals and other critical infrastructure entities that put lives or safety at risk. Ransomware attacks on hospitals typically result in cancelled appointments and surgeries, and ambulances are often put on divert, causing emergency patients to travel further to alternative facilities. These delays to patient care put patient safety at risk, and studies have shown that mortality rates increase at hospitals following ransomware attacks. Ransomware actors conduct attacks on hospitals in the full knowledge that patient care is threatened, as it increases the probability of a ransom being paid. The subcommittee members heard testimony from Cynthia Kaiser, the former deputy assistant director of the FBI’s Cyber Division from 2022 to 2025 and the current senior vice president of the Halcyon Ransomware Research...
