Updating the taxonomy of failure modes in agentic AI systems: What a year of red teaming taught us

Research page generated from configured evidence sources. Treat this as an analyst workbench: facts are sourced, gaps are labelled, and low-confidence chatter is separated from confirmed evidence.

Executive judgement

  • Priority score: 25
  • Confidence: low
  • Exploit status: none — No public exploitation signal captured by the configured pipeline yet.
  • CISA KEV: No CISA KEV match captured in configured source data at generation time.
  • Published/observed: 2026-06-04

What happened

A surge in real-world attacks against agentic AI systems is reshaping how we think about risk. Based on 12 months of red teaming, this update introduces seven new failure modes, from supply chain compromise to goal hijacking, and the practical mitigations teams need now. The post Updating the taxonomy of failure modes in agentic AI systems: What a year of red teaming taught us appeared first on Microsoft Security Blog.

Why it matters

  • The item was promoted because the pipeline observed: priority score 25, exploit status none, confidence low.
  • No CVE was extracted from the source story yet, so this should be treated as a news/campaign cluster until primary technical identifiers are found.
  • No PoC signal was detected by the current pipeline unless shown elsewhere on this page.

Evidence collected

Exploitation and PoC status

  • Current automated assessment: No public exploitation signal captured by the configured pipeline yet.
  • Public exploit/PoC: No PoC source captured yet by the configured pipeline.
  • Exploited in the wild: Not confirmed by configured sources at generation time.
  • Ransomware association: No ransomware association captured at generation time.

Dark web / low-confidence chatter

  • No matching OTX/URLhaus/MalwareBazaar item found in configured low-confidence feeds at generation time.
  • This is not proof of absence. It means the current automated sources did not capture relevant underground or malware-feed chatter.

Defender actions

  • Review Microsoft’s published mitigations for agentic AI systems and assess if any apply to internal AI deployments (e.g., prompt injection protections, sandboxing).
  • No immediate CVE or product-specific action; this is a research summary.

Exposure validation ideas

  • Search asset inventory for affected vendor/product names and any CVE reference.
  • Check internet-facing exposure through approved tools only: Shodan/Censys/GreyNoise links below are research starting points, not proof of exposure.
  • Prioritise management interfaces, edge devices, identity/control-plane systems, and OT/ICS assets where relevant.

Detection / hunting ideas

  • Review vendor logs for authentication failures, privilege changes, unexpected admin activity, and anomalous management-plane access.
  • Search SIEM/EDR telemetry for product-specific process names, network services, and newly published indicators from primary sources.
  • Monitor for scanner traffic or nuclei/metasploit module references once public exploit tooling appears.

Open questions

  • Is there a primary vendor advisory with exact affected versions and fixed versions?
  • Has CISA KEV, Shadowserver, GreyNoise, or a trusted vendor confirmed exploitation?
  • Are there credible PoC repositories or only secondary reporting mentioning PoC?
  • Is there underground/forum/leak-site discussion, or only public reporting?
