2026 Cybersecurity Threats: Identity-Based Attack Vectors
Summary
Hide ▲
Show ▼
BeyondTrust predicts that identity-based threats will dominate the 2026 cybersecurity landscape. Key threats include agentic AI vulnerabilities, account poisoning in financial systems, and dormant 'ghost' identities in identity and access management (IAM) systems. These threats exploit weak identity verification, privilege sprawl, and unmanaged identity debt. Organizations must adopt an identity-first security posture to mitigate these risks. Agentic AI, integrated into various technologies, will create new attack surfaces due to the confused deputy problem. Account poisoning will exploit automated financial systems, while historic identity compromises will be uncovered during IAM modernization efforts.

Identity-Based Threats Predicted to Dominate 2026 Cybersecurity Landscape
BeyondTrust's annual cybersecurity predictions highlight three critical identity-based threats for 2026: agentic AI vulnerabilities, account poisoning in financial systems, and historic identity compromises. These threats exploit weak identity verification, privilege sprawl, and unmanaged identity debt. Organizations must adopt an identity-first security posture to mitigate these risks. The confused deputy problem in AI, automation in financial fraud, and the uncovering of dormant identities during IAM modernization are key areas of concern.
