TL;DR: Healthcare breaches, vendor compromise, and identity abuse continue to turn trusted systems into attack paths, with incidents ranging from patient data theft to operational disruption and downstream exposure, according to ColorTokens’ threat advisory. The practical lesson is that blast radius control, not perimeter confidence, is now the decisive test of breach readiness.
NHIMG editorial — based on content published by ColorTokens: When Trusted Systems Become Attack Paths
Questions worth separating out
Q: What fails when trusted internal systems become attack paths?
A: What fails is the assumption that internal trust is safe after the first login.
Q: Why do identity systems and service accounts make breaches spread faster?
A: Identity systems and service accounts are built to transfer trust efficiently, which is exactly why they can accelerate breach spread.
Q: How do security teams know if blast radius controls are actually working?
A: They should test whether a compromised account, session, or integration can still reach management planes, production workloads, and third-party connections.
Practitioner guidance
- Map trusted control points Identify directory services, management consoles, remote administration tools, and vendor integrations that can expand access after one login.
- Separate human and non-human trust scopes Inventory service accounts, API tokens, and automation credentials as distinct risk classes.
- Reduce east-west movement paths Apply microsegmentation to management planes, directory dependencies, and business-critical workloads so one compromised system cannot freely traverse the environment.

ColorTokens' full threat advisory covers the operational detail this post intentionally leaves for the source:
- Per-incident timelines and exposure details for the hospital, benefits administrator, and manufacturer cases.
- The advisory's expanded vulnerability discussion, including the management and identity paths that let attackers spread.
- Operational impact notes on order processing, manufacturing, shipments, and downstream notification scope.
- ColorTokens' broader breach-readiness framing for microsegmentation and containment planning.

Blast-radius control is now the core breach-readiness metric. The advisory shows that the central question is no longer whether a control exists, but whether an attacker can use it to expand into identity systems, management tools, and third-party pathways. That shifts governance away from simple access approval toward containment design. Practitioners should judge trust relationships by the damage they can propagate, not by the convenience they provide.
A question worth separating out:
Q: Who is accountable when a vendor or business associate widens breach impact?
A: Accountability should be shared across the system owner, IAM or PAM owner, and supplier risk team because third-party access is part of the trust architecture. If a partner account can reach core systems, the relationship has become an attack path and should be governed like one. Contracts, access reviews, and segmentation decisions all belong in the accountability chain.
