Dispel joins White House-backed Project Lifeline 250 to secure remote access at rural hospitals
Dispel, a secure remote access vendor, is participating in Project Lifeline 250, a White House-backed six-month pilot launched October 26 to strengthen cybersecurity at rural hospitals in South Carolina. The program aims to secure network-connected medical and building systems that third-party vendors service remotely, addressing a gap where many devices cannot run security agents or enforce multifactor authentication (MFA) locally. Dispel will provide zero-trust remote access controls, session monitoring, and device isolation to help rural hospitals with limited IT staff govern vendor access and maintain operations after cyberattacks.
Why it matters: Rural hospital IT teams and biomedical staff need to reduce third-party access risk: third parties were involved in 32 percent of healthcare breaches according to Verizon's 2026 report, and many legacy medical devices lack native security controls, making remote access the critical control point.

Monitoring AI agent sessions: Leveraging embedding models to aid threat hunting and attack discovery workflows
A security researcher describes using embedding models stored in Elasticsearch to search and hunt across artificial intelligence (AI) agent sessions for anomalous behavior, comparing this deterministic approach to the probabilistic costs of running large language models (LLMs) for the same task. The method embeds each turn of an agent conversation into vectors across four channels (user input, agent reasoning, agent response, and tool calls), then performs semantic similarity searches to identify sessions needing triage. The approach surfaces one in seven sessions as review-worthy while scaling to organizations with thousands of engineers and millions of annual agent turns.
Why it matters: Security teams adopting AI agents need a scalable way to audit what agents actually do beyond keyword matching; this embedding-based method provides deterministic, reusable threat hunting that costs less than LLM-per-session evaluation and lets defenders ask new questions of historical data without expensive re-analysis.

When trust becomes the payload: Inside the threats, etc quarterly report
Elastic Security's quarterly threat report covering April through September 2026 finds that attackers increasingly abuse legitimate, trusted software such as remote monitoring and management tools, artificial intelligence (AI) coding assistants, and Microsoft applications to gain persistent access rather than deploying traditional malware. The report identifies three attack patterns: zero-malware intrusions using signed legitimate products, AI agent-driven attacks compressing thousands of actions into days, and exploitation of identity and consent flows to compromise cloud and software-as-a-service (SaaS) tenants in as little as eight minutes. Defensive strategies relying on signature-based detection fail against signed software abuse, requiring instead behavioral analytics, cross-domain visibility, and automation to detect unauthorized system-level activity.
Why it matters: Security teams and incident responders must shift detection and hunting from signature-based methods to behavioral monitoring of trusted applications, because attackers now routinely hide inside pre-approved tools and legitimate user workflows with attack chains completing in seconds to minutes.
