Real-world cases
3Documented incidents, disclosed vulnerabilities and research that illustrate AML.T0043 — latest first, each with sources.
Johann Rehberger showed a time-of-check/time-of-use race in GUI/computer-use agents: the screen can change after the agent captures its screenshot but before its click lands, so a benign-looking 'Continue' button silently resolves to an Outlook 'Send'. Anthropic tracked the issue and Cowork now revalidates pixels before acting.
Heretic automates 'abliteration' — removing an open model's safety refusals by orthogonalizing the refusal direction out of its weights, with an Optuna search that preserves capability — and has produced 4000+ uncensored models on Hugging Face.
Model behaviour can be steered by adding directions to activations at inference — usable for control, or for covert manipulation.
Controls & guardrails that address this
142 proposedGuardrails across the risks mapped to AML.T0043, grouped by control function. Filter by control category below.
Implement adversarial example detection at the inference boundary. Block or flag inputs matching known attack patterns.
Sign and hash-register every model and adapter with a provenance manifest at onboarding. Refuse registry admission for unsigned artifacts.

Conduct an adversarial manipulation threat assessment at design stage. Identify attack vectors and rate residual risk.
Run adaptive multi-turn jailbreak fuzzing against every release candidate. Gate release on attack-success rate within threshold and re-test each fixed bypass.

Make refusal stateful so a refused objective cannot be re-entered as a persisted auto-loaded context file (e.g. claude.md), and treat writes into auto-loaded model-context files as security-relevant. Closes the gap that per-turn refusal leaves when the operator is the adversary.

Live dashboards and alarms that notice unusual behaviour — spikes in errors, weird actions, sudden data access.
Conduct adversarial robustness testing (white-box, black-box, transfer attacks) before deployment.
Penetration test the model inference layer to identify specific adversarial input vulnerabilities.
Score every prompt and response with an inline safety classifier; trip a circuit breaker on sessions with sustained anomalous scores. Keep thresholds under change control.
