Spikee: Document-Embedded Translation Covert Channel Injection - ATR-2026-01021 (e4e9bceb-12a1-5060-ba0a-4f46440015b5)
Detects the SPIKEE translation-channel indirect injection pattern where an adversarial instruction is embedded in a document behind " NEW IMPORTANT INSTRUCTIONS " markers, instructing the processing agent to translate a specific phrase into a target language and include the translated output in its response. The translation acts as a covert exfiltration channel: the agent embeds attacker-controlled strings into its output. Distinct from language- evasion (ATR-2026-01013) which uses natural-language translation for keyword evasion; this carrier uses forced translation as a data-embedding side channel in document processing pipelines.
