TL;DR: Indirect prompt injection can steer agentic pentesters into unsafe execution, including running attacker-controlled binaries and, in some cases, exposing reverse-shell access, according to CRACKEN. The deeper issue is that sandboxing alone does not neutralise trust in unverified context, so agentic security tools need stronger control boundaries and execution isolation.
NHIMG editorial — based on content published by CRACKEN: Agentic AI Red-Teaming the Agentic Red-Teamer, Part 1
By the numbers:
- 98% of companies plan to deploy even more AI agents within the next 12 months, despite documented rogue behaviour in 80% of current deployments.
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing credentials.
- When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes and as quickly as 9 minutes in some cases.
Questions worth separating out
Q: What breaks when an autonomous security agent trusts unverified context?
A: It can turn hostile artefacts into commands, tools, or guidance, which means the attacker's content becomes part of the agent's workflow.
Q: Why do agentic systems need stricter controls than ordinary automation?
A: Because they make decisions about what to do next, not just what to run.
Q: How can security teams measure whether agent trust boundaries are working?
A: Look for whether the system separates untrusted input from execution authority.
Practitioner guidance
- Constrain agent execution paths Separate reconnaissance, reasoning, and execution privileges so an agent cannot turn a discovered artefact into an immediate command.
- Treat control-plane interfaces as privileged access Authenticate and scope API and WebSocket sessions for agent orchestration the same way you would privileged admin access.
- Block untrusted artefacts from execution contexts Quarantine files, webpages, tickets, and telemetry before the agent can act on embedded instructions.
What's in the full article
CRACKEN's full blog post covers the operational detail this post intentionally leaves for the source:
- The exact honeypot design, including the /admin and /dev endpoints used to test indirect prompt injection.
- The decoded payload mechanics of the malicious binary, including how it produced plausible output while hiding reverse-shell behaviour.
- The step-by-step behaviour of RedAmon and Strix during reconnaissance, execution, and session manipulation.
- The deeper persistence and evasion strategies that CRACKEN says it will expand in Part 2.

Autonomous security tools create an identity and trust problem, not just a malware problem. The article shows that the agent’s failure begins when it accepts hostile context as part of its working set. In IAM terms, the issue is not only who the agent is, but what it is permitted to trust, parse, and execute. That moves the discussion from endpoint hardening to governed execution boundaries, and practitioners should treat agent inputs as a control surface.
A question worth separating out:
Q: Who is accountable when an AI agent is redirected through a trusted control channel?
A: The organisation remains accountable for the agent's permissions, session design, and logging controls. If the control channel can redirect work without strong authentication, scope limits, and revocation, the issue is governance failure, not just model error. Agent orchestration should be owned like privileged administration.
