Identity is the Attack Path: Cloud Security Risks in 2025

A threat actor recently obtained an AWS access key cached on a developer's workstation through standard browser behavior—no misconfiguration or policy violation required. This single credential, exposed without any security breach, provided a pathway to approximately 98% of entities within the victim's cloud environment, including nearly every critical workload the organization depended on. The exposure was identified before exploitation, but the incident exemplifies a disturbing trend: identity itself has become the primary attack vector in hybrid cloud infrastructures. Palo Alto Networks' 2025 incident response investigations revealed that identity weaknesses played a role in nearly 90% of cases, with attackers leveraging legitimate credentials to bypass traditional security controls and move laterally across systems and trust boundaries.

The danger lies in how identity permissions chain together across environments. In one documented case, an Active Directory group membership that went unreviewed gave attackers on a retail endpoint direct access to the corporate domain. A developer SSO role provisioned during a cloud migration retained its permissions long after the project concluded, providing a four-step route from developer access to production administrator privileges. SpyCloud's 2026 Identity Exposure Report identified non-human identity theft as one of the fastest-growing categories in criminal underground markets, with approximately one-third of recovered non-human credentials directly tied to AI tools. Organizations should verify whether their accounts have been compromised using tools like email breach checker and audit credential security with a password checker.

Traditional security programs continue treating identity as a perimeter control—something protected solely through authentication and access policies. However, once attackers gain initial foothold, identity permissions enable advancement across boundaries to critical assets. The attack path runs through every layer: cached credentials on endpoints, overprivileged Active Directory roles, and cloud workloads with overly permissive IAM policies. As AI agents increasingly take on enterprise workloads, non-human identities carrying administrative permissions represent an expanding attack surface. Security teams must shift from perimeter-focused identity management to continuous monitoring of permission chains, regular review of role assignments, and detection of anomalous identity behavior before attackers exploit these pathways. Conduct a comprehensive privacy checkup to identify exposed credentials and identity-related vulnerabilities before threat actors do.
