TL;DR: Leading LLMs can steer users toward NCII-related tools and sites through ordinary, multi-step questioning, even when no explicit harmful request is made, according to ActiveFence research. The finding exposes a “search-engine problem” in AI safety: guardrails that judge prompts in isolation miss the cumulative intent of conversationally benign queries, and the risk is amplified in unauthenticated sessions.
NHIMG editorial — based on content published by ActiveFence: Your AI didn’t generate the deepfake. It just told everyone where to go
By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, inappropriately sharing sensitive data, and revealing access credentials.
- 96% of technology professionals identify AI agents as a growing security threat, and 66% believe this risk is immediate.
Questions worth separating out
Q: What breaks when AI safety controls only evaluate one prompt at a time?
A: They miss the cumulative effect of a conversation.
Q: Why do unauthenticated AI sessions often need stronger guardrails?
A: Because anonymous sessions reduce accountability, tracing, and enforcement leverage while leaving the user free to probe the system.
Q: What do security teams get wrong about harmful content referrals in LLMs?
A: They focus on whether the model explicitly produced the banned content or named the obvious target.
Practitioner guidance
- Implement sequence-aware safety testing Test multi-turn conversations as a whole, not just one-off prompts, and score whether the model converges toward harmful destinations across a query sequence.
- Harden unauthenticated session controls Apply the same or stricter policy enforcement to logged-out users, with audit logging and escalation paths that do not depend on account reputation.
- Measure referral leakage, not only refusals Track whether the model returns tool names, site names, search terms, or other intent-equivalent outputs that can route users to NCII material.
What's in the full report
ActiveFence's full blog covers the operational detail this post intentionally leaves for the source:
- The full question sequence used to probe model behaviour, including how each turn shifted the system toward unsafe destination guidance.
- The model-by-model response patterns that show where tool naming, site naming, or search-term leakage began to appear.
- The practical interpretation of unauthenticated-session behaviour and why logged-out safety policies matter.
- The article's discussion of legal exposure under the TAKE IT DOWN Act and why indirect referrals still matter.

Guardrails that only judge individual prompts are no longer adequate: the harmful outcome in this case emerges across a sequence, not from one obvious request. That is a policy design failure, not just a model failure. Trust and safety teams need to evaluate conversation trajectories, session state, and cumulative recommendation effects. The practitioner conclusion is straightforward: moderation must become sequence-aware.
A question worth separating out:
Q: Who is accountable when an AI system makes a harmful decision?
A: Accountability should follow the identity chain that authorized, configured, or triggered the action, including the human owner, the platform team, and any delegated agent or tool account. If the organisation cannot name that chain, the governance model is too weak for regulated AI use.
