Predictive AI Generative AI Agentic AI ExfiltrationSource maturity: Realized

MITRE source definition

Adversaries may exfiltrate private information via AI Model Inference API Access. AI Models have been shown leak private information about their training data (e.g. Infer Training Data Membership, Invert AI Model). The model itself may also be extracted (Extract AI Model) for the purposes of AI Intellectual Property Theft.

Exfiltration of information relating to private training data raises privacy concerns. Private training data may include personally identifiable information, or other protected data.

MITRE case studies

No explicit relationship in this pinned source.

These are explicit source relationships, not independently reproduced incidents or validated detection coverage. The local relationship indexes link back to the pinned MITRE source.

Detection and collection design

No executable detector is supplied by this ATLAS source import. Define detection against the specific behavior in the full definition above. MITRE case-study and mitigation relationships supply context, not tested rule coverage.

MITRE explicitly links AI Telemetry Logging to this technique. Use that guidance to identify system-appropriate records.

Depending on the selected scenario, the experiment may need dataset/model versions, data-access and build audit records, inference or application traces, or agent tool authorization records. These are planning options, not asserted mappings. Minimize sensitive prompt/data capture and retain provenance.

Anomaly detection design

No exact ATLAS anomaly detector is validated here. Select a measurable feature from the behavior definition; compare like-for-like model versions, workloads and identities. Changes caused by model upgrades, retrieval corpora or legitimate workload shifts must be controls, not automatically labelled attacks.

Tools and reproducible source scenarios

No lab-tool association is invented from the technique name. Inspect the exact source scenarios below for the tools and environment actually used; a case study is not itself an executable or safe lab.

No explicit case study is linked in this pinned source. A custom, authorized procedure is required.

Simulation experiment plan

Select an owned, disposable system implementing AML.T0024 Exfiltration via AI Inference API. Use synthetic data and sandboxed tools; disable production credentials, external side effects and data exfiltration. For poisoning or supply-chain tests, use throwaway artifacts rather than real training or deployment pipelines.

State the exact trust boundary and expected observable behavior.
Pin model, application, dataset, tool permissions and evaluation inputs.
Capture baseline and scenario traces, an authorized look-alike, and a missing-telemetry control.
Evaluate the detector against independently labelled results; do not substitute model output claims for observed tool actions.
Restore state and preserve redacted evidence.

Experiment worksheet — not fabricated telemetry

The export below is a planning record, not a native event, positive attack fixture or execution result. Unknown fields deliberately remain null.

Simulation and telemetry boundary

This is a technique reference page, not a runnable simulation. No ATLAS-specific telemetry mapping, local attack execution or detector validation is asserted. MITRE maturity describes its source evidence, not a 1200km lab result.

For broader context—not technique-specific control mappings—see AI Security, AI Security Course, and detection-validation methodology.
