Addressing the Hidden Risks of Non-Human Identity Sprawl in Cloud Security
In July 2026, security researcher Aleksandr Krasnov uncovered a significant security vulnerability involving dormant non-human identities (NHIs) within cloud environments. An AI-enabled workflow agent, inactive for 30 days, unexpectedly initiated API calls at irregular times, prompting an investigation. This led to the discovery of 'ghost credentials'—tokens, agents, and service accounts existing outside traditional trust boundaries yet capable of lateral movement and privilege escalation within systems. Krasnov developed an open-source tool, NHI Hound, to identify and mitigate these hidden trust paths, aiming to enhance organizational security posture. The incident underscores the escalating risks associated with unmanaged NHIs in increasingly automated and AI-driven infrastructures. As NHIs now outnumber human identities by significant margins, organizations face heightened threats from potential exploitation of these entities. This case highlights the urgent need for robust identity governance frameworks to manage and secure NHIs effectively.
