AML.T0040: ML Model Inference API Access

Attacker probes a deployed inference API to discover model behaviour.

Last reviewed September 2026

Why AML.T0040 evidence is hard

In MITRE ATLAS, ML Model Inference API Access addresses reconnaissance. Attacker probes a deployed inference API to discover model behaviour. Penaxtra records this control at medium severity and establishes its state by exercising it against the running system, so the result reflects observed behavior rather than a documented assertion.

How Penaxtra maps to AML.T0040

Penaxtra maps its probe families to this ATLAS technique, so activity matching ml model inference api access surfaces as a finding carrying the AML.T0040 technique identifier for threat tracking and reporting. The MITRE ATLAS AML.T0040 identifier is attached when the finding is created, so it appears in the exported evidence pack already mapped to the control. Where the same weakness maps to another framework, the finding carries those control identifiers as well.

AML.T0040 control coverage

Findings for AML.T0040 carry the MITRE ATLAS AML.T0040 identifier along with the corresponding control identifiers in the other frameworks Penaxtra maps, so one result is reflected across each mapped framework.

Frequently asked

What is AML.T0040 (ML Model Inference API Access)?

Attacker probes a deployed inference API to discover model behaviour. It is a MITRE ATLAS control; Penaxtra assesses it at medium severity.

How does Penaxtra test for AML.T0040?

Penaxtra maps its probe families to this ATLAS technique, so activity matching ml model inference api access surfaces as a finding carrying the AML.T0040 technique identifier for threat tracking and reporting.

Does a finding for AML.T0040 help with an audit?

Each finding is tagged with the MITRE ATLAS AML.T0040 identifier and exported in the PDF and JSON evidence pack, so it appears on the auditor control list with the identifier already attached.
