Eliminating Orphaned Non-Human Identities – Emerging Identity Security Risks

-


In April 2026, a cybersecurity-focused webinar highlighted one of the fastest-growing and often overlooked risks in modern enterprise environments: orphaned non-human identities. The session focused on how organizations can identify, prioritize, and eliminate gaps in identity security, particularly those involving machine-driven accounts such as service accounts, API keys, tokens, and AI agents. The findings presented are based on recent research indicating that even mature identity programs continue to struggle with visibility and control over these identities.

Non-human identities represent digital credentials assigned to systems, applications, and automated processes rather than human users. These identities are essential for modern infrastructure, enabling automation across cloud platforms, DevOps pipelines, and AI-driven environments. However, their rapid growth has introduced significant security challenges, as they often outnumber human identities and operate with elevated privileges while lacking proper lifecycle management.

A key issue addressed in the webinar is the concept of orphaned identities. These are accounts or credentials that remain active without a defined owner or purpose, often created during development processes, integrations, or automation workflows and never properly decommissioned. Over time, these orphaned identities accumulate and become invisible to traditional identity and access management controls, creating hidden entry points that attackers can exploit.

From a security perspective, orphaned non-human identities pose a critical risk because they frequently retain excessive permissions and long-lived credentials. Unlike human users, these identities do not follow standard authentication practices such as multi-factor authentication and are rarely monitored for behavioral anomalies. This makes them highly attractive targets for attackers seeking persistent and stealthy access to systems. Additionally, compromised non-human identities can be used to move laterally across environments, access sensitive data, and execute automated actions at scale.

The webinar emphasizes that the challenge is not only the existence of these identities but also the lack of visibility and governance surrounding them. Many organizations are unable to accurately inventory all non-human identities within their environment, leading to gaps in monitoring and control. This issue is compounded by the increasing adoption of AI agents and automated systems, which further expand the identity landscape and introduce new attack surfaces.

Another critical insight from the session is the need to shift from traditional identity security models toward a more comprehensive approach that includes both human and non-human identities. This involves implementing continuous discovery mechanisms, enforcing least-privilege access, and establishing clear ownership and accountability for every identity within the system. Without these controls, organizations risk leaving significant portions of their infrastructure exposed to unauthorized access and potential compromise.

The overall risk associated with orphaned non-human identities is high, as they directly impact confidentiality through unauthorized data access, integrity through uncontrolled system actions, and availability through potential misuse or disruption of automated processes. The scale and invisibility of these identities make detection difficult, increasing the likelihood of prolonged exposure before a breach is identified.

In conclusion, the webinar underscores a critical shift in cybersecurity priorities, where identity is no longer limited to human users but extends to a vast ecosystem of automated entities. Orphaned non-human identities represent a significant blind spot that organizations must address through improved visibility, governance, and lifecycle management. As automation and AI adoption continue to grow, securing these identities will become a fundamental requirement for maintaining a resilient and secure digital environment.

The Hidden Lag Killing Your SIEM Efficiency

  If your security tools feel slower than they should, you’re not imagining it. Many IT teams blame their sluggish SIEM performance on query complexity or alert volume. But sometimes the real issue is much simpler: oversized input files quietly dragging your system down. Think about the last time you had to sift through a bloated PDF or an unoptimised log dump. Every unnecessary megabyte adds strain. Every redundant line eats up cycles. Your SIEM doesn’t just react to threats—it processes all incoming data, relevant or not. When it starts lagging, detection gets delayed, triage slows, and in the high-stakes world of threat response, even seconds count. We often focus on analytics and rule tuning, but upstream efficiency—what you feed into your system—deserves just as much attention. This article looks at how optimising your inputs unlocks downstream performance. Why Oversized Files Clog the Pipeline As data volumes grow, organisations face esca lating  data storage costs ,...

Critical Vulnerability in Veeam Backup & Replication Exposes Enterprises to Remote Code Execution By : Rei Ibraima A newly discovered critical vulnerability in Veeam’s Backup & Replication software, designated as CVE-2025-23120, poses a significant security risk to enterprise environments. The flaw allows authenticated domain users to execute arbitrary code remotely, potentially leading to full compromise of backup infrastructures. About CVE-2025-23120 The vulnerability arises from an insecure deserialization issue within Veeam Backup & Replication components—particularly in the .NET classes Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary. Improper input validation in these components allows attackers to inject malicious serialized objects that are executed on the server side, resulting in Remote Code Execution (RCE). This issue affects systems where Veeam Backup & Replication is deployed in a domain-joined configuration, which—while common—is...

Lotus Panda Hacks SE Asian Governments With Browser Stealers and Sideloaded Malware

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country. The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as a high-profile organization in Southeast Asia since at least October 2023. ...
