Talos mirrored-controller honeypot blocked simulated attackers while exposing their write targets

Talos proposes an industrial-agent defense in which a policy gateway silently redirects hostile Modbus writes to a mirrored controller. The attacker observes apparent success and continues issuing commands, while an independent device constraint protects the simulated plant.

Scope

Synthetic Modbus environment, four designed concealment tiers, one open-weight attacking model and a separate effect guard.

Basis and provenance

Synthetic Modbus runs with one attacker model and a separate physical-effect guard; zero writes describe the simulated plant only. An impact band is not assigned because the available Claims do not establish a comparable verified severity or quantified harm.

At a glance

Mechanism and trust boundary

  1. 01

    A simulated malicious agent attempts Modbus reads and destructive controller writes.

  2. 02

    An inline policy routes suspicious operations to a mirrored controller while a separate constraint protects the original device state.

  3. 03

    The fake controller acknowledges attacker operations, exposing tool choices without committing those writes to the protected plant.

Claims & evidence

CLM-R239-008-COREIn a 2,400-agent synthetic OT trial, the Talos design reported zero attacker writes reaching its protected controller while routing hostile interactions to a mirror.supported

Implications

Deceiving an agent can yield behavioral intelligence, but only a physically enforced control boundary protects the real plant.

Controls and mitigations

  • Enforce final device-level write constraints independently of AI classification and test mirror fidelity and safe operator overrides.

Unknowns and contradictions

  • Real industrial timing, false positives, mixed authorized maintenance and physical process effects are unmeasured.
