Orphaned Non-Human Identities: The Silent Attack Surface Hiding in Your Stack

Non-human identities - service accounts, API keys, OAuth tokens, machine credentials - now vastly outnumber human users in most enterprise environments, and a growing share of them are orphaned. They belong to deprecated services, departed developers, or one-off integrations nobody documented, yet they retain live permissions against production systems. Attackers know this, and credential-based intrusions increasingly trace back to forgotten machine identities rather than phished employees.

The Hacker News is hosting a webinar focused on discovering these orphaned NHIs, mapping their entitlements, and decommissioning them without breaking dependent workloads. The pitch centers on inventory-first approaches: you cannot rotate or revoke what you cannot see, and most identity governance tooling was built around humans, not workloads.

The broader signal here is that NHI sprawl has crossed from niche concern to mainstream identity risk. Organizations treating service accounts as set-and-forget infrastructure are accumulating standing privilege debt that compounds with every cloud migration, CI/CD pipeline, and SaaS integration.
