Abstract
This paper describes deliberately exposing decoy API credentials and returning intentionally harmful
responses to parties attempting misuse. The intended objective is to inflict the maximum amount of
harm on the opposing system through counterattacks delivered via the response itself. This states
intent, not an established technical result, an endorsement of retaliation, or a claim of novelty. The
discussion covers conceptual categories of poisoned and harmful responses, including prompt-
injection content, outputs designed to induce an adversarial AI to exfiltrate its tooling to a
government or security-researcher destination, token-wasting or resource-exhausting replies, and
other adverse effects on automated consumers. It distinguishes these from merely misleading decoy
data and considers safeguards for good-faith users, including security scanners and neutral
credential-validity inquiries. Caller intent cannot reliably be inferred from an API request. Existing
Amazon and IBM disclosures already describe deceptive returned information and artificial or masked
responses; whether those disclosures encompass deliberately harmful content, prompt injection, or
maximum-harm objectives remains unresolved. This is a conceptual publication draft, without an
implementation or evidence of safe or lawful operation.
Keywords: decoy credential; API counterattack; poisoned response; prompt injection; token waste;
malicious honeypot; intended harm; good-faith validation; attribution uncertainty; patent scope.
