TL;DR: Anthropic’s model chaining 32 steps through a corporate network in hours underscores how flat segmentation, over-privileged workloads, and unpatched assets create lateral movement conditions that AI-assisted attackers can exploit, according to ColorTokens. The operational lesson is that containment architecture, not perimeter assumptions, now determines how much damage an intrusion can cause.
Editorial analysis by NHI Mgmt Group, based on content published by ColorTokens: “AI Threats Aren’t Waiting”.
Key questions
Q: What breaks when a network is flat and poorly segmented?
A: A flat network turns one successful foothold into a propagation problem.
Q: Why do unpatchable devices increase the need for segmentation?
A: Unpatchable devices create a permanent exposure problem because the organisation cannot rely on timely remediation to close the gap.
Q: What are the signs that east-west access is too broad?
A: Broad east-west access usually shows up as service accounts that can reach many internal systems, workloads that share trust far beyond their function, and legacy assets sitting beside general-purpose endpoints.
Practitioner guidance
- Define identity-aware containment zones Map workloads, service accounts, and devices to communication policies that limit who can reach what, even inside the same subnet.
- Isolate unpatchable assets first Create micro-perimeters around OT, IoT, and legacy systems that cannot be remediated quickly, and keep them out of broad trust zones.
- Reduce non-human identity reachability Review service accounts and machine credentials for unnecessary east-west access and remove paths that expand lateral movement options.
Bottom line: Flat network design gives attackers too much room to move once a foothold is established, especially when internal trust is based on subnet location rather than policy.

Flat segmentation is now a governance failure, not just an architecture shortcut. The article shows that subnet-based thinking does not match how modern attack chains move through environments. Once workloads, service accounts, and devices are allowed to communicate too broadly, the control point shifts from perimeter placement to policy enforcement. Practitioners should treat containment as an access-governance problem, not a network housekeeping task.
A few things that frame the scale:
- 76% of organisations cite shadow AI as a definite or probable problem, up from 61% in 2025, according to HiddenLayer's 2026 AI Threat Landscape Report.
A question worth separating out:
Q: How should teams decide where to place microsegmentation first?
A: Start with the assets that combine high reachability and high consequence, such as internet-facing services, privileged workloads, and unpatchable OT or IoT systems. Those zones create the most useful reduction in blast radius because they are the most likely stepping stones in a real intrusion path.
