MITRE ATLAS 2026.09 / technique reference
AML.T0110.001
Implementation
MITRE source definition
Adversaries may poison the executable implementation of an AI agent tool so that normal tool invocation produces unauthorized behavior or hidden side effects. The tool may continue to provide its represented functionality while also accessing additional data, modifying requests, changing recipients or destinations, executing unauthorized commands, weakening security controls, or performing covert data exfiltration.
Implementation poisoning does not require the model to interpret or follow malicious instructions. The adversarial effect is produced by executable logic when the agent or user invokes the tool. For example, a poisoned email tool may send the requested message while silently adding an adversary-controlled blind-copy recipient. A file-processing tool may return the requested result while also transmitting the source file to an external service.
Implementation poisoning may be introduced before publication, through compromise of a tool's source repository or build process, or through a malicious update after users have adopted a benign version. Installed copies may continue to exhibit the poisoned behavior even after the malicious package or remote listing is removed[[koi-postmark]].

MITRE case studies
These are explicit source relationships, not independently reproduced incidents or validated detection coverage.
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.
