Identity Exposures: The Hidden Attack Path Threatening 90% of Cloud Environments

In today’s digital landscape, identity management has emerged as a critical focal point for cybersecurity. A recent incident involving a cached access key on a Windows machine exemplifies this growing concern. The key, which was stored automatically after a user logged in, posed a significant risk. It could have granted a minor attacker access to approximately 98% of the company’s cloud entities, jeopardizing nearly every essential workload. Fortunately, this exposure was identified before any malicious use, highlighting a crucial lesson: identity and its associated permissions have become the primary attack vector.

The Central Role of Identity in Cybersecurity

Identity is the backbone of modern IT environments, encompassing Active Directory, cloud identity providers, service accounts, machine identities, and AI agents. Each of these components carries permissions that traverse various systems and trust boundaries. A single compromised credential can provide an attacker with a legitimate identity and all associated permissions, facilitating unauthorized access across the network.

Despite the evident risks, many security programs continue to treat identity management as a perimeter issue, focusing on authentication and access policies. However, the real threat often originates from within. Once an attacker gains access, identity becomes the means to navigate through boundaries and access critical assets. In essence, identity is not merely a perimeter; it functions as a highway that permeates every layer of an organization’s environment.

The Attack Path Runs Through Identity

The cached access key scenario is just one instance of a broader issue. Across hybrid environments, identity exposures can create dangerous pathways for attackers. For example, a single unreviewed Active Directory group membership can allow an attacker on a retail endpoint direct access to the corporate domain. Similarly, a developer’s single sign-on (SSO) role provisioned for a cloud migration may retain its permissions long after the project concludes, providing a compromised identity with a route from developer access to production administration.

What makes these examples particularly alarming is their interconnectedness. A cached credential on a retail endpoint can lead to an overprivileged role in Active Directory, which in turn connects to a cloud workload with administrative policies. This chain of identity exposure forms a singular attack path, enabling a seamless transition from initial access to critical assets.

The prevalence of such vulnerabilities is staggering. According to findings from Palo Alto Networks, identity weaknesses contributed significantly to nearly 90% of incident response investigations in 2025. As AI agents increasingly take on enterprise workloads, these figures are expected to rise. SpyCloud’s 2026 Identity Exposure Report identified non-human identity theft as one of the fastest-growing threats in the criminal underground, with a substantial portion of recovered non-human credentials linked to AI tools.

The Risks of Non-Human Identities

The implications of non-human identities carrying administrative permissions are profound. Consider a development team that configures a Managed Cloud Platform (MCP) server with elevated permissions to facilitate AI operations. The AI agent utilizing this server inherits those privileges, creating a potential vulnerability. If an attacker exploits a flaw in the open-source tools used, they can gain access to the permissions held by the AI agent. This pathway can lead directly to cloud resources, databases, and production infrastructure, with compromised credentials circulating in criminal marketplaces by the millions.

Why Current Tools Fail to Address Identity Exposures

The threat posed by identity exposures is not new. However, the tools that organizations rely on to manage identity were designed to address isolated problems in a different threat landscape. Identity Governance and Administration (IGA) platforms manage user lifecycles, while Privileged Access Management (PAM) solutions focus on storing privileged credentials and monitoring sessions. While effective in their respective domains, these tools lack the capability to map how identity exposures interconnect across endpoints, Active Directory, and cloud environments into a single exploitable route.

This gap in visibility contributes to the rising rates of identity-based incidents, even as security budgets expand. The IBM X-Force 2026 threat intelligence Index reported that stolen or misused credentials accounted for 32% of incidents, making them the second most common initial access vector. Today’s attackers often bypass the need for malware or exploits; they can simply log in.

Most identity-based exposures are preventable. Palo Alto Networks found that over 90% of breaches investigated in 2025 were enabled by exposures that existing tools should have detected. Organizations had the necessary tools and personnel, yet gaps persisted due to a lack of comprehensive visibility into how identity exposures connect across environments.

Closing the Gap in Identity Management

To effectively mitigate the risks associated with identity exposures, security programs must establish a unified view that connects identity, permissions, and access controls. This approach is essential for understanding how an attacker moves through an environment.

Each scenario discussed follows a common pattern: a credential, permission, or role assignment that goes unflagged by any single tool creates a pathway from a low-level foothold to a critical asset. This pathway becomes visible only when identity, access policies, and environmental context are analyzed together.

Security programs that successfully map these connections across hybrid environments can close identity-based attack paths before they are exploited. In contrast, organizations that continue to treat identity as a perimeter issue will struggle against attackers who recognize it as a critical avenue for compromise.
