Attack path

Expanded Definition

An attack path is the connected route an attacker can use after gaining trusted access, moving through identities, permissions, services, and data stores until higher-value impact becomes possible. In NHI security, the term is broader than a single compromised account because it captures how privilege chains, trust relationships, and weak segmentation combine into a usable path.

Definitions vary across vendors when the term is applied to cloud security, identity graphs, or agentic systems, but the operational meaning is consistent: a path exists only when traversal is possible, not merely when a vulnerability is present. That distinction matters because an exposed secret, an over-permissioned service account, and an admin API are often separate issues until they connect into one reachable route. NHI Management Group treats attack paths as a governance problem as much as a technical one, especially where service accounts can pivot into infrastructure, CI/CD, or sensitive data stores. For adjacent context, see the Ultimate Guide to NHIs — Key Challenges and Risks and the OWASP NHI Top 10. A useful external reference for path-based defense is the CISA cyber threat advisories.

The most common misapplication is treating a compromised credential as the full incident, which occurs when teams stop at the initial foothold and ignore the downstream privileges it can reach.

Examples and Use Cases

Implementing attack path analysis rigorously often introduces graph complexity and response overhead, requiring organisations to weigh clearer exposure visibility against the cost of continuous mapping and prioritisation.

• A leaked API key from a CI system is not the endpoint; the attack path may continue into artifact storage, deployment permissions, and production data access.
• A service account with broad RBAC rights can pivot from a low-sensitivity application to a secrets manager, turning a minor compromise into a major breach route.
• A compromised AI agent token may let an attacker invoke tools, read connected files, and trigger workflows, creating an agentic attack path that is still evolving across the industry.
• An exposed cloud credential can be chained into lateral movement if the identity is trusted by multiple workloads, as highlighted in the LLMjacking: How Attackers Hijack AI Using Compromised NHIs research from Entro Security.
• Identity teams may use external graphs and standards guidance such as the MITRE ATLAS adversarial AI threat matrix to model how tool access and credentials combine into reachable abuse paths.

When analysing paths, practitioners should trace not only permissions but also trust inheritance, token reuse, secret location, and cross-environment connectivity. The Ultimate Guide to NHIs and the 52 NHI Breaches Analysis both show how weak visibility makes those connections easy to miss.

Why It Matters in NHI Security

Attack paths matter because NHI compromise rarely stays local. A single exposed secret can become a route to production systems, cloud control planes, and sensitive data if the identity behind it has standing privilege or unreviewed trust links. NHI Management Group research shows that 97% of NHIs carry excessive privileges and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, which is exactly the condition that turns a foothold into a reachable path.

That is why path reduction belongs in governance, not just incident response. Teams need to identify where secrets are stored, where service accounts are trusted, and where one workload can impersonate another. The Top 10 NHI Issues and the 52 NHI Breaches Report both reinforce that visibility gaps and excess privilege turn isolated mistakes into breach chains. External threat reporting from CISA cyber threat advisories and the Anthropic report on AI-orchestrated cyber espionage show how quickly trusted access can be abused once it is reachable.

Organisations typically encounter attack paths only after a credential theft, lateral movement, or production disruption, at which point the term becomes operationally unavoidable to address.
