Output Integrity Attack

A security attack where the attacker changes or interferes with the final output of a machine learning model

The Explain card

Plain English
An output integrity attack changes or interferes with the final output of a machine learning model after it has been produced, so consumers receive a result the model never actually gave.
Example
Malware on an inference server rewrites fraud-detection verdicts in transit, flipping "suspicious" to "approved" for selected transactions, while the model itself remains untouched.
Why it matters
A perfect model is useless if the pipe after it is tampered with. Defenders sign or authenticate model outputs, protect the inference path, and monitor for verdicts that disagree with expected patterns.
Hook
The oracle spoke the truth; the messenger rewrote it.
